       BACKGROUND OF THE INVENTION 
       [0003]    Exercise is important to maintaining a healthy lifestyle and individual well-being. Accordingly, many individuals want to participate in an exercise program. The most successful exercise programs are ones tailored to a fitness level of an individual and aimed at assisting the individual to achieve one or more specific fitness or exercise goals. 
         [0004]    Sports trainers, as well as other exercise and fitness professionals, are available to assist individuals in developing exercise programs appropriate for their individual fitness levels and their specific fitness or exercise goals. Hiring such professionals, however, can be expensive. Furthermore, the busy schedules of many individuals make it difficult for these individuals to set aside time to meet with an exercise and fitness professional on a routine basis. Thus, many individuals forego using the services of exercise and fitness professionals, and they never achieve the benefits that can be obtained from an exercise program tailored, for example, to one&#39;s fitness level. 
         [0005]    Technology has resulted in the development of systems capable of transferring performance information obtained from a user during a workout to a remote computer for further analysis. These systems often provide a user interface that allows the user to review their past performance data. 
         [0006]    What is needed are improved program products, methods, and systems for providing fitness monitoring services that will allow athletes to, among other thing, better use data generated from past performances to gauge their improvement, to set goals for the future, to share their performance data with others, to stay motivated, and/or to enable them to exercise at intensities appropriate for their current fitness level and goals.

The cable connecting the portable fitness monitoring device  102  and the computer  114  may be a USB cable with suitable USB plugs including, but not limited to, USB-A or USB-B regular, mini, or micro plugs. 
         [0070]    Wireless communication between the portable fitness monitoring device  102  and the personal computer  114  may be achieved, for example, by way of a wireless w′de area network (WWAN—such as, for example, the Internet), a wireless local area network (WLAN), or a wireless personal area network (WPAN) (collectively, wireless area networks or WANs). As is well known to those skilled in the art, there are a number of known standard and proprietary protocols that are suitable for implementing WANs (e.g. TCP/IP, IEEE 802.16, and Bluetooth). Accordingly, the present invention is not limited to using any particular protocol to communicate between the portable fitness monitoring device  102  and the various external elements of the fitness monitoring service of the present invention. 
         [0071]    In one embodiment, the portable fitness monitoring device  102  may communicate with a WWAN communications system such as that employed by mobile telephones. For example, a WWAN communication system may include a plurality of geographically distributed communication towers and base station systems. Communication towers may include one or more antennae supporting long range two-way radio frequency communication wireless devices, such as the portable fitness monitoring device  102 . The radio frequency communication between antennae and the portable fitness monitoring device  102  may utilize radio frequency signals conforming to any known or future developed wireless protocol, for example, CDMA, GSM, EDGE, 3G, IEEE 802.x (e.g., IEEE 802.16 (WiMAX)), etc. The information transmitted over-the-air by the base station systems and the cellular communication towers to the portable fitness monitoring device  102  may be further transmitted to or received from one or more additional circuit-switched or packet-switched communication networks, including, for example, the Internet. 
         [0072]    As shown in  FIG. 2 , communication may also occur between the personal computer  114  and a server  112  via a network  110 . In an embodiment, the network  110  is the Internet. The Internet is a worldwide collection of servers, routers, switches and transmission lines that employ the Internet Protocol (TCP/IP) to communicate data. As indicated above, the Internet may also be employed for communication between the portable fitness monitoring device  102  and the personal computer  114 . In one embodiment of the present invention, information may be directly communicated between the portable fitness monitoring device  102  and the server  112  via the network  110 , thus bypassing the personal computer  114 . 
         [0073]    According to embodiments of the fitness monitoring service of the present invention, a wide variety of information may be communicated between any of the athlete  100 , the personal fitness monitoring device  102 , the personal computer  114 , the network  110 , and the server  112 . Such information may include, for example, performance parameters, training advice, training plans, calendar data, route information, music, videos, text, images, voice communications, settings, software, and firmware. 
         [0074]    Communication among the various elements of the present invention may occur before a physical activity is commenced, after a physical activity has been completed, and/or in real time during the physical activity. In addition, the interaction between, for example, the personal fitness monitoring device  102  and the personal computer  114 , and the interaction between the personal computer  114  and the server  112  may occur at different times. 
         [0075]    Information communicated to and stored by the server  112  may be accessible to the athlete  100  at a later time via the network  110 . For example, the athlete could access post-activity performance information communicated to the server  112  from their personal fitness monitoring device  102  at a later time from their personal computer. In another embodiment of the present invention, a third party (e.g. a trainer, coach, friend, or family member) stationed at a personal computer  114  may be able to access real-time or historical performance information regarding the athlete&#39;s performance via the server  112  over the network  110 . 
         [0076]      FIG. 3  is a diagram of an exemplary software configuration of server  112 . The application software of server  112  includes a number of different modules capable of providing fitness monitoring services to athletes  100 .

Each module supports one or more graphical user interfaces (GUIs) capable of being presented to users at one or more remote personal computers  114 . 
         [0077]    As is known by those of skill in the art, a GUI may use a combination of technologies and devices to provide a platform the user  100  can interact with via a computer  114 . A GUI may offer, for example, graphical elements, visual indicators, and text to represent information and actions available to the user  100 . Graphical elements may include, for example, windows, menus, radio buttons, check boxes, and icons. The user  100  may use a physical input device, such as a mouse, to control the position of a cursor  206  on their computer  114  screen. 
         [0078]    Those skilled in the art will appreciate that alternative or additional modules and sub-modules may be implemented within the server  112  system in order to provide or extend the described or additional functionalities. For example, the software configuration of server  112  may include an operating system, which may be one of the commercially available operating systems such as, for example, Windows, UNIX, LINUX, Mac OSX, or AIX. The operating system may also have an associated application programming interface through which middleware and application programs may access the services of the operating system. In addition, a hypertext transport protocol (HTTP) server may run on top of the operating system. As is well known in the art, HTTP server may communicate data over the Internet using HTTP. 
         [0079]    According to one embodiment of the present invention,  FIG. 4  illustrates a GUI window presented by start module  200  to a user of a remote personal computer  114  system. 
         [0080]    As illustrated by  FIGS. 4-7 ,  9 - 37 , and  39 - 47 , the various modules of the fitness monitoring service of the present invention may support GUIs through which a user  100  can interact with the fitness monitoring service. As will be appreciated by those of skill in the art, in one embodiment the GUIs may appear as webpages provided by a server  112  via a website that may be accessible to the user over the Internet  110  using a web browser on their computer  114 . In other embodiments, the GUIs may be generated by a processor based only on information stored on the personal computer  114 , a CD-ROM, a mobile phone, or other computer readable media accessible locally to the user  100 . In embodiments of the present invention, users  100  can, among other things, use data generated from past performances to gauge their improvement, set goals for the future, share their performance data with others, and/or assist themselves in exercising at intensities appropriate for their current fitness level and goals. 
         [0081]    With reference to  FIG. 4 , a menu bar  204  may be present near one of the edges of a GUI window of the present invention. The menu bar  204  may include several icons or indicia corresponding to the start  200 , plan  300 , schedule  400 , track  500 , support  600 , library  700 , and forum  800  modules. In one embodiment, the menu bar  204  may be present on every GUI page presented to the user by the server. After logging in to the server  112 , the user  100  may be able to navigate to areas of the website supported by different modules by selecting their corresponding icons with a cursor  206 . Additional icons corresponding to sub-modules or program wizards associated with a particular module may pop up or otherwise be displayed to the user  100  if the user  100  selects or hovers the cursor  206  over a module icon. 
         [0082]    In order to access the features of embodiments of the present invention, a user  100  stationed at a remote personal computer  114  may log into the server  112  via the interne  110 . As is well known to those skilled in the art, the login process, which may be controlled by a log in wizard  202  run by start module  200 , typically includes the entry by the remote user  100  of a login ID and password or other authentication information to the server  112 , which then authenticates the identity of the user  100  by reference to a user database or the like. Embodiments of the fitness monitoring services of the present invention may be offered to a plurality of athletes  100  or other users  100  forming a user community, may be restricted to users  100  that have been issued login IDs and passwords for accessing the server  112 , and/or may further be offered in exchange for a subscription fee. 
         [0083]    Following the preliminary authentication process via the log in wizard  202 , as illustrated in  FIG. 5 , a social networking wizard  208  run by the start module  200  may invite the user to link their fitness monitoring account to a social networking site, such as, for example, Facebook, MySpace, Twitter, Friendster, LinkedIn, or the like. As explained in further detail below, linking to a social networking site may provide the user  100  with added benefits and features. If the user declines the initial opportunity to link to a social networking site, they may be able to create such a link at a later time. Upon completion of the social networking wizard  208 , start module  200  may present a home page, as illustrated in  FIG. 6 . 
         [0084]    In an embodiment, the user  100  stationed at a remote personal computer  114  may alternatively choose to interact with the server  112  via a software widget. As is known by those of skill in the art, a software widget is a software application including portable code intended for one or more different software platforms. The term “software widget” implies that either the application, user interface, or both, may be relatively simple and easy to use, as exemplified by a desk accessory or applet. 
         [0085]    In one embodiment, the software widget may be a desktop widget that is a specialized GUI widget intended to run on a computer desktop. In another embodiment, the software widget may be a mobile widget that can operate on mobile devices (e.g. smart phones). The widget may present a simplified version of the user interfaces explained in further detail herein, and may provide alternative means for the user to log in to the server  112 . The widget may allow the user to review summary information about their past performance, and may allow the user to view, for example, a calendar of upcoming workouts, as described in further detail below. 
         [0086]    From the home page, the user  100  may be able to navigate to different modules, sub-modules, or wizards by selecting their corresponding icons from the menu bar  204  with the cursor  206 . In one embodiment, by hovering the cursor  206  over the start module  200  icon, the user  100  may be able to select an introductory sub-module  210 , an equipment sub-module  212 , or a device download sub-module  214 . 
         [0087]      FIG. 7  is an exemplary GUI window that may be displayed by the introductory sub-module  210 . The introductory page may contain general information about the fitness monitoring system of the present invention, including a brief description of the system, its intended users, and the potential benefits available to those users. 
         [0088]    For example, the introductory page may contain information about the planning, scheduling, and tracking capabilities of the fitness monitoring system. In one embodiment of the present invention, some aspects of the planning, scheduling, and tracking functions may be tied to a color-coded heart rate zone system. In other embodiments, some aspects of the planning, scheduling, and tracking functions may be tied to color-coded zone systems based on zones of other parameters including, but not limited to, speed, pace, stride rate, calories, respiration rate, blood oxygen level, blood flow, hydration status, or body temperature. A graphical representation and a brief description of such a color-coded system may be provided on the introductory page and in personal settings, as illustrated in  FIG. 7 . 
         [0089]    In an embodiment of the present invention, the color of certain graphical information provided by the server  112  via the various GUIs presented may be dictated by detected or targeted heart rate information. Various modules of the fitness monitoring service of the present invention may be programmed with algorithms for establishing one or more heart rate ranges or “zones.” Each zone may be associated with a particular color. Zones may be defined, for example, as ranges of percentages of an athlete&#39;s  100  maximum heart rate. Accordingly, each zone may be associated with a particular level of effort. 
         [0090]      FIG. 8  is an exemplary illustration of the zone definitions according to one embodiment of the present invention. An energy zone, ranging from 65% to 75% of an athlete&#39;s  100  maximum heart rate, is associated with the color blue. An endurance zone, ranging from 75% to 85% of an athlete&#39;s  100  maximum heart rate, is associated with the color green. A strength zone, ranging from 85% to 90% of an athlete&#39;s  100  maximum heart rate, is associated with the color yellow. Finally, a power zone, ranging from 90% to 95% of an athlete&#39;s  100  maximum heart rate, is associated with the color red. These ranges and color combinations are exemplary only; numerous other ranges and/or colors could be used. 
         [0091]    In an embodiment, an additional zone (for example, a pink zone) may also be provided that overlaps the ranges of the blue, green, and yellow zones. The pink zone may primarily be used for setting intensity goals for beginners. In a further embodiment, the colors may change in character from relatively light or dim colors to relatively dark or intense colors as values associated with the zone colors increase from the lower to upper limits of the zone. 
         [0092]    The zones may be assigned based on predetermined fitness goals. For example, in the embodiment of  FIG. 8 , the energy zone (blue) may be associated with a heart rate range that allows an athlete  100  to build their aerobic base. The endurance zone (green) may be associated with a heart rate range that allows an athlete  100  to build cardiovascular strength and burn calories. The strength zone (yellow) may be associated with a heart rate range that allows an athlete  100  to improve their aerobic threshold, endurance, and metabolism. The power zone (red) may be associated with a heart rate range that allows an athlete  100  to improve their anerobic threshold, endurance, and metabolism. 
         [0093]    For planning purposes, that zones can be presented to the user  100  as an indication of the difficulty of a particular workout. For monitoring and tracking purposes, the zones may be established for a particular user  100  based on a maximum heart rate. An athlete&#39;s  100  maximum heart rate may not be an indication of their fitness level, it usually may not change significantly with training, and it may be set by the athlete&#39;s  100  genetics. An athlete&#39;s  100  maximum heart rate can be provided to the fitness monitoring service of the present invention in a number of ways. 
         [0094]    Returning to the functionality of the start module  200 ,  FIG. 9  is an exemplary GUI window that may be displayed by the equipment sub-module  212 . The equipment page may contain an overview of the different pieces of equipment that are compatible with the fitness monitoring system of the present invention. Such pieces of equipment may include, for example, mobile fitness phones, dedicated portable fitness monitoring devices, non-dedicated portable fitness monitoring devices, sports mode-enabled MP3 players, sports mode-enabled dongles, sports watches, display devices, exercise machines in fitness centers, and sensors (e.g. pedometers or heart rate sensors). A broad overview of each piece of equipment and/or more detailed specifications may be provided. A table or interactive equipment wizard  216  may further be provided to help the athlete  100  select the equipment that best suits the athlete&#39;s  100  needs and fitness goals. 
         [0095]    The equipment wizard  216  may pose a series of questions to the athlete  100  or the athlete&#39;s  100  coach such as, for example, “What are your personal fitness goals?”, “Do you already have a dedicated portable fitness monitoring device?”, “Do you want to receive performance feedback and/or coaching during your activity?”, “Do you want to log performance data during your activity?”, “Would you like to be able to listen to music during your activity?”, “Would you like to monitor your heart rate?”, “Would you like to monitor your speed?”, “Would you like to use GPS-enabled features?”, and “Would you like to be able to transmit and receive data to and from your device in real-time?”, Other interactive questions for determining and/or fulfilling the needs of the user  100  may be included. 
         [0096]    The equipment page provided by the equipment sub-module  212  may further prompt or allow user&#39;s  100  to purchase the equipment through the equipment page, may provide links to other websites where the user  100  could purchase the equipment, and/or may provide information about physical retail outlets where the user  100  could purchase the equipment. 
         [0097]      FIG. 10  is an exemplary GUI window that may be displayed by the device download sub-module  214 . The device download page may contain software and firmware downloads and or updates for users  100 . For example, a synchronizer program could be downloaded to a user&#39;s  100  personal computer  114  that could manage communications between the portable fitness monitoring device  102  and the personal computer  114 . The user  100  could activate the synchronizer program while using their personal computer  114 , and utilize it to transfer software and firmware updates to the portable fitness monitoring device  102  or to update settings or options on the portable fitness monitoring device  102 . Like the application software of the server  112 , the synchronizer program running on the user&#39;s  100  personal computer  114  could also support one or more GUIs capable of being presented to the user  100  at the computer  114 . Thus, the user  100  may be able to, among other things, update settings or options on the portable fitness monitoring device  102  without being connected to the server  112  via the network  110 . In embodiments of the present invention, portable fitness monitoring device  102  settings and options may also be adjustable directly via the portable fitness monitoring device  102  itself, depending on its particular configuration. 
         [0098]    As indicated above, in embodiments of the present invention, the menu bar  204  may be present on every GUI page presented to the user by the server  112 . Accordingly, at any time, the user  100  may be able to navigate to portions of the website supported by different modules, sub-modules, or wizards by selecting their corresponding icons from the menu bar  204  with the cursor  206 . In one embodiment, the user  100  may be able to select an icon corresponding to the plan module  300  from the menu bar  204 . 
         [0099]      FIG. 11  is an exemplary GUI window that may be displayed by the plan module  300 . From the main plan module page, the user  100  may be able to select from one of a plurality of icons corresponding to training plans. Additional icons corresponding to training sub-plans may pop up or otherwise be displayed to the user  100  if the user  100  selects or hovers the cursor  206  over a training plan icon. 
         [0100]    In one embodiment of the present invention, from the main plan page, the plan module  300  may enable the user  100  to select training plan icons with the cursor  206  associated with various training plan sub-modules, such as, for example, a Learn to Run sub-module  302 , a Be Fit sub-module  304 , a Run a Race sub-module  306 , a De-Stress sub-module  308 , a Lose Weight sub-module  310 , and a Finish Faster sub-module  312 . 
         [0101]      FIGS. 12-17  are exemplary GUI windows that may be displayed by the various plan module  300  sub-modules  302 - 312 . Each plan module  300  sub-module may be associated with a different training plan having a different intended athlete user  100  audience and different goals. For example, the earn to Run sub-module  302  may provide a plan where the beginner athlete  100  walks and runs at relatively easy paces in order to build their fitness base. An athlete  100  utilizing the Learn to Run program may be encouraged to master the basics of heart rate training, improve their running form, and/or learn to enjoy running. 
         [0102]    The Be Fit sub-module  304  may provide a plan where the athlete  100  runs at slightly faster paces in order to improve their overall physical fitness. An athlete  100  utilizing the Be Fit program may be encouraged to, for example, increase their cardiovascular capacity and conduct interval training (i.e. sequentially running at different intensities for different periods of time or for different distances). 
         [0103]    One or more of the plan module  300  sub-modules may also be designed for athletes  100  who are interested in physical activities besides—or in addition to—running. For example, the Be Fit sub-module  304  may also provide a plan where the athlete  100  works out in a gym using various machines and pieces of stationary exercise equipment to improve their overall physical fitness. An athlete  100  utilizing the Be Fit program may be encouraged to, for example, increase their cardiovascular capacity and conduct interval training on various machines and pieces of stationary exercise equipment. 
         [0104]    The Run a Race sub-module  306  may provide a plan for athletes  100  interested in preparing for a race. In one embodiment of the invention, the Run a Race sub-module  306  may provide a plurality of different plans depending on the distance of the race the athlete  100  is planning to participate in. Plans may be provided, for example, for 5K, 10K, ½ marathon, and full marathon races. An athlete  100  utilizing one of the Run a Race programs may be encouraged to, for example, conduct interval or other speed work training, take long runs and recovery runs, and generally build their endurance and aerobic capacity so that they are able to successfully complete their race. 
         [0105]    The De-Stress sub-module  308  may provide a plan where the user&#39;s  100  primary goal may be to reduce their overall stress, achieve relaxation, and increase energy. A user  100  participating in the De-Stress program may, for example, be guided through a series of workouts of varying intensities that are regularly scheduled, but of relatively short duration, so that the user  100  is able to de-stress on a regular basis yet will still be able to find time in their schedule to complete their workouts. 
         [0106]    The Lose Weight sub-module  310  may provide a plan for users  100  interested in burning calories, reducing body fat, increasing energy, and improving overall health through aerobic workouts. Again, the particular physical activities performed by the user  100  are not limited. A user  100  participating in the Lose Weight program may, for example, be guided through a consistent workout schedule that starts at a relatively easy level to build the user&#39;s  100  athletic base and establish a regular routine, and that may gradually progress to more difficult workouts. 
         [0107]    Like the Run a Race sub-module  306 , the Finish Faster sub-module  312  may provide a plan for athletes  100  interested in preparing for a race. However, the finish faster module  312  may be more appropriate for athletes  100  who have significant race experience and are looking to improve upon their past race times. An athlete  100  participating in the Finish Faster program may be encouraged to conduct interval training and speed work, and push themselves to the limit by conducting longer and more intense workouts. 
         [0108]    In another embodiment of the present invention, a Recover sub-module may provide a plan for users who need to recover from a difficult race (e.g. a marathon), from an injury, or from any other physically, mentally, or emotionally taxing event. An athlete  100  participating in the Recover program may be given different goals depending on the specific situation. Athletes  100  recovering from a difficult race may only need a short series of relatively easy recovery runs to get their legs back for resumed training. Athletes recovering from an injury may need a much longer recovery period, depending on the severity of the injury. Athletes recovering from mentally or emotionally taxing events may be provided with a variety of goals, some of which may be similar to those provided in a De-Stress plan. 
         [0109]      FIGS. 12-17  are exemplary GUI windows that may be displayed by the various plan module  300  sub-modules  302 - 312 . Each plan sub-module page may include a description of the plan, including its intended athletic users  100  and its goals. Each plan sub-module page may further include a level selector  314  and a plan preview  316 . The particular information displayed by the plan preview  316  may depend on a level selected via the level selector  314 . 
         [0110]    When considering the selection of a particular training plan, the associated plan sub-module may allow the user  100  to select from a plurality of difficulty levels for their prospective program using the level selector  314 . The level selector  314  may be an icon, a drop down menu, a slider, or any other GUI input device known in the art. In one embodiment, the user  100  may be able to choose from one of seven difficulty levels, where level 1 is the easiest and level 7 is the most difficult level. 
         [0111]    In another embodiment, the user&#39;s  100  difficulty level options may be limited based on the particular training plan sub-module selected. For example, as illustrated in  FIG. 12 , the Learn to Run sub-module  302  may only be capable of presenting levels 1 through 3. Because a user  100  who is just learning to run or begin an exercising is not likely to desire a program of high difficulty, such a limitation may be appropriate. On the other hand, as illustrated in  FIG. 17 , the Finish Faster sub-module  312  may only be capable of presenting levels 6 and 7. Because a user  100  who has participated in several competitive races before has likely achieved a high level of physical fitness, such a limitation may also be appropriate. 
         [0112]    In one embodiment, the user&#39;s  100  difficulty level options may be limited based on the particular training plan sub-module selected because of certain filters in place. In an embodiment, the user  100  may be able to deactivate or modify these filters in order to be able to choose from a wider variety of levels for a given plan. Alternatively, such filters may not be present, and a user  100  may be free to chose any level for any plan. 
         [0113]    Once a difficulty level for a prospective plan has been selected via level selector  314 , the particular training plan sub-module provides the plan preview  316  for the plan. The plan preview  316  may include a description of what to expect from the plan, a description of the benefits of the plan, and/or a sample schedule. The plan description may make reference to the particular color-coded heart rate zones that a user  100  may be prompted to exercise at as part of that plan. As illustrated in  FIGS. 12-17 , the sample schedule may include an indication of the number of total workouts in the plan, the number of workouts per week, and the total number of weeks. 
         [0114]    The training plan sub-module may also provide a sample workout list  318  for a given plan. The user  100  may access the sample workout list  318  by selecting an appropriate icon with their cursor  206 . In one embodiment, the icon may be a bar graph representing the relative durations and intensities of the individual workouts of the plan. The durations of the individual workouts may be proportional to the length of the bars displayed, while the intensities of the individual workouts may be indicated by a color corresponding to the heart rate zone at which the user  100  will be instructed to exercise.  FIG. 18  shows an exemplary GUI pop-up window providing the sample workout list  318  provided by the Run a Race sub-module  306  for a user  100  who has selected a level 4 10K race program. 
         [0115]    In one embodiment, for each workout, the list  318  provides the workout number in the series (e.g.  40  of  51 ), a zone bar indicator  320 , the workout duration, calories, or distance targetted (e.g. 28 minutes, 400 calories, or 5 kilometers), and a coaching tip. The zone bar indicator  320  may communicate several pieces of information. It may indicate the number of intervals to be performed. It may also indicate the relative intensities of each interval to be performed, based on a target heart rate zone, as indicated by a color. For example, as illustrated in  FIG. 18 , workout number  41  consists of one time interval of blue training (corresponding to, for example, an energy zone ranging from 65% to 75% of an athlete&#39;s  100  maximum heart rate). Workout  42  consists of three time intervals of training—a long interval of green training (corresponding to, for example, an endurance zone ranging from 75% to 85% of an athlete&#39;s  100  maximum heart rate) preceded and followed by short intervals of blue training. Workout  43  consists of four time intervals of training, including two blue intervals, a green interval, and a yellow interval (corresponding to, for example, a strength zone, ranging from 85% to 90% of an athlete&#39;s  100  maximum heart rate). In this way, the athlete  100  can gauge the relative level of difficulty and suitability of a prospective training plan by examining the zone bar indicators  320  associated with the individual workouts making up a prospective plan. 
         [0116]    The coaching notes included in the workout list  318  may provide motivation, point out a particular area of focus, or otherwise provide guidance to the athlete  100  related to the ultimate goal of their particular plan. 
         [0117]    After determining which plan best suits their needs, the athlete  100  may select an icon that enables plan module  300  to launch a plan personalization wizard  322 . The questions presented by the plan personalization wizard  322  may vary depending on the type of plan selected.  FIG. 19  shows an exemplary personalization wizard  322  GUI window provided by the Run a Race sub-module  306  for a user  100  who has selected a level 4 10K race program. 
         [0118]    The plan personalization wizard  322  may prompt the user  100  to select a start date for their training plan, so that the plan may be built forward from that date. For users  100  who select a race-oriented plan (such as those provided by the Run a Race sub-module  306  or the Finish Faster sub-module  312 ), personalization wizard  322  may prompt the user  100  to select the day of their race, so that the plan may be built backward from the race date. 
         [0119]    The plan personalization wizard  322  may also prompt the user  100  to select which days of the week they want to conduct their workouts on. For example, as illustrated in  FIG. 19 , a user  100  may choose to workout, four days per week on Sundays, Tuesdays, Thursdays, and Saturdays. In other embodiments, users  100  may be able to plan workouts to occur on different days during different weeks. 
         [0120]    Wile personalizing their plan, the user  100  may be able to vary the number of workouts per week by adding removing a workout day from their selection. In an embodiment, the system may then dynamically alter the total number of workout and total weeks of the workout plan, and display this information via the plan personalization wizard  322 . Depending on the overall goals of the plan selected by the user  100 , the system may or may not increase or decrease the total number of workout and/or the total number of weeks of the plan in response to the user  100  adding or removing a workout day from their schedule. For example, if a user  100  personalizes a plan to include workouts on only two days per week, the system may extend the plan over a longer period of time and/or add more total workouts. In contrast, if the user  100  personalizes a plan to include workouts on 6 days a week, the system may reduce the number of weeks of the plan and/or decrease the total number of workouts. 
         [0121]    The plan personalization wizard  322  may further prompt the user  100  to give their plan a name. In one embodiment, the wizard  322  may provide a default name. In this way, a user  100  who wishes to schedule multiple training plans may be able to distinguish one plan from another by the plans&#39; names. 
         [0122]    In one embodiment, after the user  100  finalizes their plan via the personalization wizard  322 , schedule module  400  may populate a GUI calendar  402  with the user&#39;s  100  plan. In addition, at any other time when the user  100  is logged in to the server  112 , the user  100  may be able to navigate to the GUI calendar  402  by selecting the icon corresponding to the schedule module  400  from the menu bar  204 . 
         [0123]      FIG. 20  is an exemplary GU window according to an embodiment of the present invention containing the calendar  402  that may be displayed by the schedule module  400  for a user  100  who has selected a Finish Faster level 7 marathon race program. From the calendar  402  page, the user  100  may be able to view the individual workouts of their training plan populated throughout the calendar  402 . The individual workouts populated into the calendar  402  may be represented by a zone bar indicator  320  similar to that provided by the plan module  300  via the sample workout list  318 . The calendar  402  may also indicate the duration of each workout scheduled for each date. The GUI page containing the calendar  402  may also provide an indication of the number of workouts and/or number of weeks remaining for the current plan. 
         [0124]    In one embodiment, the user may be able to access a workout list  318  containing a listing of all workouts of their currently selected plan by selecting an appropriate icon with their cursor  206 . This workout list may be identical to one of the sample workout lists  318  provided by plan module  300 . The workout list is another way of presenting the workout information populated on to calendar  402 . 
         [0125]    From the calendar  402  page, the schedule module  400  may enable the user  100  to select icons with the cursor  206  associated with various schedule wizards, such as, for example, a plan editor wizard  404  and a custom workout wizard  406 . 
         [0126]      FIG. 21  shows an exemplary plan editor wizard  404  GUI pop-up window, according to an embodiment of the present invention, that may be provided for a user  100  who has selected a Finish Faster level 7 marathon race program. The plan editor wizard  404  may allow the user  100  to, for example, reset their training schedule to start (or end) on a new date, choose a new day of the week for their long run, end their plan entirely, or adjust their schedule and calendar  402  to skip a given number of workouts in the plan. 
         [0127]      FIG. 22  shows an exemplary custom workout wizard  406  GUI pop-up window, according to an embodiment of the present invention. The custom workout wizard  406  may allow a user to add workouts to their calendar  402  regardless of whether or not they are currently participating in a scheduled plan program. If a user  100  is participating in a scheduled plan program, the custom workout feature may be used to supplement the plan with additional workouts, remove workouts, or edit workouts as the user  100  desires.  FIG. 22  shows an exemplary custom workout wizard  406  GUI pop-up window that may be provided for a user  100  who is already involved in a Finish Faster level 7 marathon race program. When a new workout is added, the wizard  406  may allow the user  100  to schedule the workout for a single date or schedule reoccurring instances of the workout on their calendar  402 . For example, the user  100  could select to have the custom workout repeated weekly, or once every other week, on any day of the week. The user  100  may also be able to select a start and end date for any reoccurring workouts. The custom workout may also be named and saved. In one embodiment, while viewing the calendar  402  page, saved custom workouts may appear in a sidebar and the user  100  may drag and drop a custom workout into any date on the calendar  402  using their cursor  206 . 
         [0128]    In an embodiment, the custom workout created by the user may include one or more intervals of varying intensities according to the color-coded zone-based system described above. The custom workout wizard  406  may enable the user  100  to build an individual workout, for example, by assembling a series of zone intervals. The user may indicate the number of intervals to be performed and the relative intensities of each interval to be performed, based on a target heart rate zone (or other parameter-based zone), as indicated by a color. In one embodiment, the user  100  may assemble a custom workout with GU elements that may resemble the graphical representation of the color-coded zone system as illustrated in  FIG. 7 . In an embodiment, the user  100  may originally be presented with a blank screen upon which they can drag, drop, stretch, or otherwise manipulate one or more colored boxes that represent intervals to be performed at specific intensities, as indicated by the color of the box. Stretching or shrinking the boxes may increase or decrease the duration of the interval associated with that box. In another embodiment, the user could numerically specify their desired number of intervals, their associated durations, and/or their associated intensities, and a GUI representation consisting of several colored boxes may automatically be produced. In an embodiment, the user  100  could specify a primary exercise interval and could click check boxes indicating that a warm-up and/or cool-down interval should also be inserted before or after their primary exercise interval, if desired. After a workout is finalized and saved, the workout built by the user  10  may be represented by a zone bar indicator  320 , as described above. 
         [0129]    In addition to creating customized individual workouts, in an embodiment, the user  10  may be able to create an entirely customized training plan from scratch. Via the plan module  400 , the user  100  may be able to create an original plan by specifying, for example, the number of weeks, the number of workouts per week, and the characteristics of the individual workouts, as described with respect to the custom workout wizard above. 
         [0130]    Once the athlete  100  has selected a training plan that has been populated onto the calendar  402 , the athlete  100  may begin to engage in physical activities in accordance with the training plan. As illustrated in  FIG. 1 , the athlete  100  may be equipped with a portable fitness monitoring device  102 . The portable fitness monitoring device  102  may be worn, carried, or otherwise supported by the athlete  100  during the physical activity. The portable fitness monitoring device  102  may also attach to a piece of exercise equipment such as a road bike traveling on a bike path or a stationary bike in the gym. The portable fitness monitoring device  102  may be capable of measuring and/or processing various performance parameters associated with the athlete&#39;s  100  physical activity. The portable fitness monitoring device  102  may communicate with one or more sensors  104 , such as a heart rate sensor, for detecting the performance parameters. As discussed above with reference to  FIG. 2 , communication of performance parameters (such as heart rate or speed) may occur between two or more of the portable fitness monitoring device  102 , the personal computer  114 , and the server  112  via a network  110  (such as the Internet). 
         [0131]    In an embodiment of the present invention, performance parameters for a plurality of athletes  100  may be stored on the server  112  and associated with particular user accounts by reference to a user database or the like. The track module  500  allows the users  100  to review and analyze their past performance data. 
         [0132]    After completing a workout and uploading performance data to the server  112 , the user  100  may log in to the server  112  to review and analyze their past performance data. In one embodiment, by hovering the cursor  206  over the track module  500  icon, the user may be able to select a workout journal sub-module  502  or a history sub-module  504 . The user may also be provided with a link to view data from their latest workout via the history sub-module  504 , as described in further detail, below. 
         [0133]      FIG. 23  is an exemplary GUI window that may be displayed by the workout journal sub-module  502 . In one embodiment, for each completed workout, the workout journal page may list the date the workout was completed, the name of the workout, and one or more performance details about the workout. For example, the workout journal page may list the elapsed time of the workout, the calories burned by the workout, the distance covered by the workout, the user&#39;s  100  average heart rate during the workout, the user&#39;s  100  average pace during the workout, the user&#39;s  100  average stride rate during the workout, a subjective user rating  506  of the workout and/or route, and any other notes  508  the user  100  wishes to record. The particular information displayed on the workout journal page may be set by the system or customized by the user  100 . Various information columns may be added or removed by the user as desired. 
         [0134]    In an embodiment, the workout journal sub-module  502  may provide a listing of all workouts completed by the user  100  using the portable fitness monitoring system. By default, the workouts may be listed in order by date. The user  100  may also be able to sort the displayed workout data by category. For example, if the user  100  wanted to sort all of their workouts by average heart rate, the user might click on the “heart rate” column header with the cursor  206 , causing the workout journal sub-module  502  to sort the workout data accordingly. A user  100  may only want to view workouts from a specific date range. Accordingly, in one embodiment, the user  100  may be able to select a specific week, month, or year for which to view workout data. By selecting a particular listed workout with the cursor  206 , the user  100  may be able to view more detailed data from that workout via the history sub-module  504 , as described in further detail below, with respect to  FIG. 27 . 
         [0135]    The subjective user rating  506  may be assigned by the user  100  immediately after the workout is completed, or at a later time. In one embodiment, the user  100  may rate a workout on a one to five star scale, with a one star workout being a poor workout and a five star workout being an excellent workout. In one embodiment, the user rating  506  may be entirely subjective. Alternatively, the user rating  506  may be assigned by track module  500  (or one of its sub-modules), based on various recorded performance parameters from the workout, historical user  100  performance, and/or user settings and options. 
         [0136]    The user notes  508  may also be assigned by the user  100  immediately after the workout is complete or at a later time. User notes may include, for example, explanations of a user rating  506  assigned to the workout, or other subjective or objective observations about the workout, the user&#39;s  100  condition, the environment the workout was conducted in, or the route traversed. 
         [0137]    In addition to (or in place of) being able to review and analyze past performance data via the workout journal sub-module  502 , the user  100  may be able to select an icon capable of initiating the history sub-module  504 . The history sub-module  504  may be capable of displaying a variety of GUI windows to the user such as, for example, those shown in  FIGS. 24-35 . 
         [0138]    In one embodiment of the present invention, there may be overlap between the information displayed by the workout journal sub-module  502  and the history sub-module  504 . The user  100  may prefer that information be displayed via one module for certain purposes and the other module for other purposes. 
         [0139]      FIG. 24  is an exemplary GUI window according to an embodiment of the present invention that may be displayed by the history sub-module  504 . History pages may include a dashboard  510 , a primary display  512 , and a sidebar  514 . The dashboard  510  may provide icons that are correlated to particular performance parameters. Each icon itself may provide information about the performance parameters, and selecting a specific icon with the cursor  206  may alter the information displayed by the primary display  512 . The sidebar  514  may provide additional information, icons, and/or options. 
         [0140]    The information displayed on the history pages may be for a single workout or for a plurality of workouts falling within a particular date range. Information may be displayed on a yearly, monthly, weekly, or daily basis. The data range selected by the user  100  may affect the information displayed by the dashboard  510  icons, the information displayed on the primary display  512 , as well as the content of the sidebar  514 . 
         [0141]    With reference to  FIG. 24 , for example, the user  100  may select and the history sub-module  504  may provide a history page displaying past performance information on a weekly basis from Jun. 29, 2008, through Sep. 20, 2008. The user  100  may have selected this date range by locating a workout in the workout journal display via workout journal sub-module  501 , selecting that workout, and then selecting a weekly display via the history sub-module. Alternatively, the user  100  may have navigated directly to the history page via the history sub-module  504 . A user  100  viewing a weekly history page may be able to move forward or backward in time to alter their display by selecting and dragging a scrollbar  516  with their cursor  206 . The scrollbar  516  may be included, for example, within the primary display  512 . 
         [0142]    The dashboard  510  shown in  FIG. 26  includes display icons for time, calories, distance, heart rate, pace, and stride rate. The numerical information provided with the dashboard  510  icons corresponds to data associated with workouts from the date range selected. For example, as illustrated in  FIG. 24 , for the selected period of Jun. 29, 2008, through Sep. 20, 2008, the user&#39;s total workout time was 52 hours, 52 minutes, and 16 seconds. This value may also be provided in cumulative and/or average faun over the selected time period. 
         [0143]    While the information provided by the dashboard  510  icons may remain the same for a given date range, the information displayed by the primary display  512  may change depending on which dashboard  510  icon the user  100  has selected. For example, in  FIG. 24 , because the user  100  has selected the time icon in the dashboard  510 , the history sub-module  504  displays time information in the primary display  512 . In  FIG. 25 , because the user  100  has selected the heart rate icon in the dashboard  510 , the history sub-module  504  displays heart rate information in the primary display  512 . Note that in both  FIGS. 24 and 25  the numerical information displayed by the dashboard  510  icons has not changed because the date range remains the same. 
         [0144]    While the figures show the information displayed by the primary display  512  in the form of bar graphs, other suitable graphical displays such as, for example, line graphs, pie graphs, racecourse representations, animations, or videos may be provided in addition to or in place of the bar graphs. Moreover, although only time and heart rate graphs have been illustrated by the figures, any performance parameters listed in the dashboard  510  may be graphically displayed in the primary display  512 . 
         [0145]    As illustrated in  FIG. 24 , when a weekly display is selected, cumulative and/or average data for a plurality of weeks is displayed in the primary display  512 . For example, for the selected period of Jun. 29, 2008, through Sep. 20, 2008, separate bars may be displayed for the weeks of June 29 th  through July 5 th , July 6 th  through July 12 th , July 13 th  through July 29 th , etc. 
         [0146]    As shown in  FIG. 25 , when weekly heart rate information is displayed in the primary display  512  in bar graph form, the heart rate information may be conveyed based on the color-coded heart rate zone system described above with respect to  FIGS. 7 and 8 . Likewise, when weekly pace, stride rate, or other parameter information is displayed in the primary display  512  in bar graph form, the pace, stride rate, or other parameter information may be conveyed based on a color-coded zone system corresponding to these other parameters. 
         [0147]    In one embodiment, as illustrated by  FIG. 25 , a color-coded bar may be provided for each week. The color-coded bar may include, for example, blue, green, yellow, and red regions associated with various heart rate zone ranges, as described above. The y-axis of the graph displayed in the primary display  512  may be time-based, and the total height of each weekly color-coded bar may correspond to the cumulative workout time for a weekly period. The relative heights of the individual color-coded regions within a given bar may be proportional to the amount of time the athlete  100  spent in that heart rate zone corresponding to each color for the weekly period. 
         [0148]    For example, in the embodiment of  FIG. 25 , during the week of August 3 rd  through August 9 th , the athlete  100  worked out for a time period of approximately eight hours and spent time working out in each of the four heart rate zones, but primarily worked out in the green heart rate zone. 
         [0149]    An athlete  100  who wants to obtain more specific information about a period of time displayed within the primary display  512  may hover their cursor  206  over the appropriate graphic to display a GUI pop-up window containing such information. For example, for the weekly time display shown in  FIG. 24 , the athlete  100  has hovered their cursor  206  over the bar representing the week of July 13 th  through July 19 th . The displayed pop-up window may indicate the time, calories, distance, heart rate, pace, an/or stride rate information for only the specific week selected by the athlete  100 . The particular information displayed in the pop-up window may be set by the system or customized by the user  100 . Various information may be added or removed by the user as desired. Note that this information is taken from a smaller period of time than the information concurrently displayed in the dashboard  510 . 
         [0150]    In one embodiment, an athlete  100  who wishes to obtain more specific information about a period of time displayed within the primary display  512  may alternatively select the bar or other indicium representing the appropriate time period with their cursor  206  (e.g. by clicking on the bar or other indicium). For example, if the user  100  viewing the weekly GUI window of  FIG. 25  wanted to obtain more specific information about the week of August 3 rd  through August 9 th , the user  100  could select the bar representing that week, which may result in the history sub-module  504  displaying the daily GUI window shown in  FIG. 26 . The resulting window may show data for only the previously selected range (i.e. the week of August 3 rd  through August 9 th ), or it may show a slightly broader date range, as showing  FIG. 26 , which provides daily information from July 27 th  through August 16 th . 
         [0151]    The history display shown in  FIG. 26  is similar to that shown in  FIG. 25  except that specific workout dates, as opposed to weeks, are displayed in the primary display  512 . Accordingly, the cumulative and/or average information displayed in the dashboard  510  is also from a narrower date range. 
         [0152]    An athlete  100  who wishes to obtain even more specific information about a period of time displayed within the primary display  512  may select the bar or other indicium representing the appropriate time period with their cursor  206  (e.g. by clicking on the bar or other indicium). For example, if the user  100  viewing the daily GUI window of  FIG. 26  wanted to obtain more specific information about workouts conducted on Aug. 9, 2008, the user  100  could select the bar representing that day, which may result in the history sub-module  504  displaying the daily GUI window shown in  FIG. 27 . 
         [0153]    The history display shown in  FIG. 27  is similar to that shown in  FIG. 26  in that the dashboard  510 , primary display  512 , and sidebar  514  are still present. However,  FIG. 27  differs from  FIG. 26  in that information provided in both the dashboard  510  and the primary display  512  is only associated with a single workout day. Additional functionality may also provided by the sidebar  514 . 
         [0154]    In one embodiment of the present invention, as shown in  FIG. 27 , the history sub-module  504  may provide a feedback  518  section in the sidebar  514 . The feedback section may provide feedback from coaches, friends, or other individuals authorized to provide feedback to the athlete  100 . All users of the system of the present invention having similar accounts through server  112  may be authorized to provide feedback to the athlete  100 . Alternatively, only users of the system that are specifically authorized by the athlete  100  may provide feedback to the athlete  100 . In an embodiment, users who are linked to the athlete  100  via a social networking site may also provide feedback to the athlete  100 . Feedback may be provided through a GUI provided by sever  112 , via email, via text message, via voice mail, or by any other suitable means known in the art. Feedback may be listed sequentially in the order that the feedback was posted, much like comments associated with a blog or other web article, as is known by those of skill in the art. 
         [0155]    The history sub-module  504  may also provide a notes section in the sidebar  514 . The notes section may provide a section for a user rating  506  and user notes  508 . These ratings  506  and notes  508  may be similar to those described above with reference to  FIG. 23 . 
         [0156]    The history sub-module  504  may provide a route tools section in the sidebar  514  that may be managed by a route tools sub-module  520 . In one embodiment, the route tools sub-module  520  may allow the user  100  to associate specific routes with a workout when the workout involved the traversal of a particular geographic pathway. In one embodiment, the route tools sub-module may employ a web-based mapping service application, such as, for example, the Google Maps application provided by Google, Inc. of Mountain View, Calif. The mapping service application may utilize an application programming interface that allows the mapping service application, such as Google Maps, to be embedded into the GUI windows of the present invention. 
         [0157]    As illustrated in  FIG. 28 , the route tools sub-module  520  may enable the user  100  to recreate the path they traversed during the workout by clicking, and/or dragging and dropping landmarks and paths over a street map using the cursor  206 . The approximate area of the route may be found by, for example, entering a street address, a well-known landmark, or a zip code into the mapping service application interface. Alternatively, in an embodiment, the athlete  100  could conduct their workout using a GPS-enabled portable fitness monitoring device  102  capable of recording their geographic way points along the route traversed. Either during traversal of the route or after the route has been completed, the GPS data could then be uploaded to the server  112  and associated with other performance monitoring information collected during traversal of the route. Thus, the route tools sub-module  520  could automatically reconstruct the path traversed by the athlete  100 . 
         [0158]    In another embodiment, the route tools sub-module may allow the athlete  100  to create, store, share, and find route plans of interest. The route plan, which may or may not be associated with a particular workout, may be created or selected that specifies a particular route for the athlete  100  to travel. In an embodiment, the route plan may be downloaded to the portable fitness monitoring device  102 . Athletes  100  may use route plans they themselves have created and stored on the sever  112 . In one embodiment, other users  100  may post and share route plans with others. In one embodiment this functionality may be enabled by the forum module  800 . Thus, a plurality of users  100  may be able to create, store, share, find, edit, rate, and comment on route plans of interest. 
         [0159]    In an embodiment, the portable fitness monitoring device  102  may be able to guide the athlete  102  along a route, based on the route plan and, for example, the athlete&#39;s  102  current position based on GPS readings. 
         [0160]    In one embodiment, the user may save and name a route or route plan using the route tools sub-module  520 . In the embodiment of  FIG. 29 , as shown in the sidebar  514 , the user  100  has named and saved a plurality of routes or route plans to the server  112 . In the event that a particular route or route plan has not been automatically assigned to a given workout record, the user  100  may wish to select a route or route plan with the cursor  206  to associate with their workout. 
         [0161]    Saved routes or route plans may be displayed in primary display  512  if the user  100  selects an appropriate icon. Route details such as the route name, distance, and location may be provided in a GUI pop-up window. The user  100  may also be able to assign a subjective rating and include notes about the route. These features are analogous to the user rating  506  and user notes  508  features described above with respect to  FIG. 23 . 
         [0162]    In an alternate embodiment of the present invention, the various route functionalities described herein may be provided through a separate route module of the application software of server  112  at the same functional level as the other primary modules illustrated in  FIG. 3 , such as the start module  200 , the plan module  300 , the schedule module  400 , the track module  500 , the support module  600 , the library module  700 , and the forum module  800 . Accordingly, a route module icon may be provided on the menu bar  204 . 
         [0163]    In another embodiment of the present invention, as illustrated in  FIG. 30 , the history sub-module  504  may further provide a playlist  522  section in the sidebar  514 . If the user  100  conducted a workout while listening to music on a music-enabled portable fitness monitoring device  102  (or with a portable fitness monitoring device coupled to a music device), the playlist  522  section may provide a listing of the musical audio tracks that the user  100  listened to during their workout. 
         [0164]    In an embodiment, a particular play list may be associated with a particular route plan or workout so that the play list may be downloaded to the portable fitness monitoring device  102  simultaneously with the route plan and/or workout. Accordingly, the user  100  may be able to easily perform the same workout and/or traverse the same route while listening to the same play list. The athlete  100  could also fine tune their play list until the athlete felt that the play list provided appropriate entertainment, motivation, or other benefits during the physical activity. 
         [0165]    As illustrated in, for example,  FIGS. 27 and 30 , the history sub-module  504  may be capable of displaying a variety of performance parameter information about a particular workout in the dashboard  510  and primary display  512  areas of a GUI window. As was the case with the weekly and daily summary displays of performance information shown in  FIGS. 24-26 , while the information provided by the dashboard  510  icons may remain the same for a given workout, the information displayed by the primary display  512  may change depending on which dashboard  510  icon the user  100  has selected. For example, in  FIG. 30 , because the user  100  has selected the heart rate icon in the dashboard  510 , the history sub-module  504  displays heart rate information in the primary display  512 . 
         [0166]    In an embodiment, the heart rate information provided with the heart rate icon in the dashboard  510  is an average heart rate in beats per minute over the entire workout. In another embodiment, the heart rate information provided with the heart rate icon in the dashboard  510  is a percentage indicating how often the athlete  100  was exercising at the appropriate heart rate, as indicated by their workout plan for the given workout (i.e. their “percentage in zone”). The percentage in zone may be based on time or distance. For example, an athlete&#39;s  100  plan may call for a 30 minute jog in the blue zone followed by a 30 minute run in the green zone. The athlete  100  may cover 4 miles during the blue zone jog while staying in the proper zone 80% of the time, and 8 miles during the green zone run, while staying in the proper zone 40% of the time. Accordingly the athlete&#39;s  100  percentage in zone for the entire run based on time would be 60%, while the athlete&#39;s  100  percentage in zone for the entire run based on distance would be approximately 53%. Percentage in zone based on one or both of time and distance may be displayed at a given time. 
         [0167]    In one embodiment, a “success rate” may be calculated and provided to the user  100 . In this manner, the user may receive performance feedback about a particular workout or series of workouts. The success rate may be displayed in the dashboard  510  and may be provided in cumulative and/or average form. In an embodiment, the success rate may be equal to the percentage in zone. In another embodiment, the success rate may be proportionate to the percentage in zone. Other factors may be used to calculate the success rate including, but not limited to, whether a personal best for a particular parameter (e.g. time, pace, distance, etc.) was achieved during a workout, whether the athlete  100  left a zone too early, whether the athlete&#39;s  100  heart rate appeared to recover quickly after completing a difficult zone interval, whether the athlete&#39;s  100  performance was consistent throughout the workout, and/or how the athlete performed during specific key interval training sessions. 
         [0168]    After the zones have been initially defined, the portable fitness monitoring system may be adapted to selectively adjust the limits of the zones in response to the athlete&#39;s  100  performance and/or feedback received from the athlete  100 , if such adjustments are warranted, as illustrated in  FIG. 38 . In this manner, the portable fitness monitoring system may provide a training feedback loop. As described above, the zones may be defined based on user input. User  100  performance parameter data is detected during a physical activity via the sensors  104 , as described above. The performance parameter data is transmitted to the personal computer  114  and/or the server  112  for processing. A determination is made as to whether the zones need to be adjusted. If adjustments are warranted, this data may be communicated back to a portable fitness monitoring device  102 . 
         [0169]    The determination as to whether or not the zones need to be adjusted may be based on, for example, the factors described above with respect to success rate calculations. In one embodiment, if the athlete  100  performs outside the specified heart rate zone for all or a portion of the interval, the heart rate zone may be adjusted. For example, if the athlete  100  is consistently above the specified zone, the zone range may be increased. If the athlete  100  is consistently below the specified zone, the zone range may be decreased. 
         [0170]    Determinations may further be influenced by feedback provided by the athlete  100 . For example, the athlete  100  may provide responses to questions posed by the portable fitness monitoring system. For example, upon uploading recently recorded performance parameter data, or upon logging in to the personal computer  114  and/or server  112 , a GUI pop-up window may appear asking the user  100 , for example, if they thought the workout routine was too difficult or too easy. If the user  100  responds that a workout routine was too difficult, the zone range may be incrementally decreased. If the user  100  responds that a workout routine was too easy, the zone range may be incrementally increased. The athlete&#39;s  100  answers to these questions may also influence the success rate calculations described above. 
         [0171]    Returning to  FIG. 30 , in one embodiment, the performance information to be displayed in the primary display  512 , based on the selected dashboard  510  icon, may be displayed on a line graph whose x-axis is either time or distance based, and whose y-axis is correlated to the value of the measured performance parameter. For example, as shown in  FIG. 30 , a line graph charts heart rate information as a function of time during the workout. 
         [0172]    Average lines may also be plotted parallel to the x-axis across the graphs. For example, in  FIG. 30 , an average heart rate line representing the athlete&#39;s  100  average heart rate of 155 beats per minute during the workout is plotted across the graph. 
         [0173]    In an embodiment, certain performance parameters may be simultaneously plotted or overlaid on top of other performance parameters. For example, in  FIG. 31 , the athlete&#39;s  100  pace has been plotted on top of the athlete&#39;s  100  heart rate as a function of time. 
         [0174]    The user  100  interested in viewing instantaneous performance statistics throughout the workout may be able to select and drag a scrollbar  516  with their cursor  206  along the x-axis. The scrollbar  516  of this embodiment may function similarly to the scrollbar  516  described with reference to  FIG. 24 . As the user  100  drags the scrollbar  516  across the x-axis, an icon may travel along the line graph plotted for the performance parameter of interest. In addition, a pop-up window displaying additional instantaneous performance data may appear and move across the screen along with the moving icon.  FIG. 32  is an illustration of an icon and pop-up window containing instantaneous performance parameter information being moved across a GUI screen by means of a scrollbar  516 . 
         [0175]    In another embodiment, the user  100  may be able to display summary performance information for a subset of the workout in the dashboard  510 . In one embodiment, the user  100  may manipulate first and second analysis boundaries  524  and  526 . The user  100  may enable use of the analysis boundaries by selecting an icon with their cursor  206 . Once analysis boundaries are enabled, a first analysis boundary marker  524  may appear on the left side of the performance parameter graph in primary display section  512 , and a second analysis boundary marker  526  may appear on the right side of the performance parameter graph in primary display section  512 . As shown in  FIG. 33 , using the cursor  206 , the user may drag and drop the first and second analysis boundary markers  524  and  526  so that only a subset of the performance parameter graph (the portion remaining between the two analysis boundary markers) is highlighted. When analysis boundaries are enabled, the numerical performance parameter information displayed in the dashboard  510  is only summed and/or averaged for the subset of the workout highlighted within the analysis boundary markers. 
         [0176]    When heart rate information is selected and displayed in the primary display  512 , icons representing the red, yellow, green, and blue zones may be positioned on the right side of the heart rate graph in primary display section  512 . The user  100  may select or hover the cursor  206  over one of these icons to display summary information for only the portions of the workout where the user  100  was performing in the zone associated with the selected icon. For example, in  FIG. 34 , the user  100  has selected the green icon on the right side of the heart rate graph. History sub-module  504  then displays a pop-up window that may detail, for example, the numerical heart rate range corresponding to the selected zone for the particular user  100  during that particular workout, as well as time, distance, heart rate, and pace information associated with the user&#39;s  100  activity in the selected zone during the workout. 
         [0177]    In an embodiment, the user  100  may be able to manually correct any recorded parameters that they know are inaccurate. Inaccuracies may be due to, for example, errors with the sensors  104  employed by the portable fitness monitoring device  102  used by the athlete  100 . As shown in  FIG. 35 , a user  100  may correct, for example, the distance they traveled during a workout. The user  100  may know the exact distance of a route routinely traveled and wish to update a distance inaccurately recorded by a distance sensor  104 . 
         [0178]    In another embodiment, when a parameter, such as distance, is corrected, the system may recalibrate the recorded and stored data. For example, when the distance traversed for a particular run is corrected, the distance data and corresponding distance graph for that run is corrected. In addition, data and graphical displays that depend on the distance data, such as pace data and graphical displays, are also corrected. 
         [0179]    In a further embodiment, when a parameter, such as distance, is corrected, this corrected data may be transmitted to the portable fitness monitoring device  102  the next time the device is in communication with the network  112  so that the portable fitness monitoring device&#39;s  102  distance monitoring capability can be recalibrated, if necessary. 
         [0180]    The track module  500  may also provide a front page sub-module  530 .  FIG. 36  is an exemplary GUI window that may be displayed by the front page sub-module  530 . The front page GUI may include plan tracker  532 , achievements  534 , last workout  536 , next workout  538 , and coach talk  540  sections. In an embodiment, the contents of the front page may be customized and reordered similarly to customizable web portals such as, for example, the iGoogle web portal. 
         [0181]    The achievements section  534  may provide icons that are correlated to particular performance parameters. In this way information displayed by the achievements section  534  on the front page may be similar to information displayed by the dashboard  510  of the other history pages. When a user  100  selects a performance parameter icon in the achievements section  534 , cumulative and/or average information about that parameter for various time periods may be displayed in the achievements section  534 . For example, as shown in  FIG. 36 , heart rate percentage in zone may be displayed for the entire time the user  100  has used the portable fitness monitoring system, since a specific date, in the last week, or in the current week. The particular information displayed in the achievement section may be set by the system or customized by the user  100 . Various information may be added or removed by the user  100  as desired. 
         [0182]    In an embodiment, the last workout section  536  displays stats for the last workout completed by the user  100 , and the next workout section  538  displays information about upcoming planned workouts. The information provided by the achievements  534 , last workout  536 , and next workout  538  sections may be similar to information provided to the user  100  by other modules and sub-modules, but may conveniently be provided on a single page. The coach talk section  540  may provide information similar to that provided by the coaching tips included in the workout list  318 , as described above with respect to  FIG. 18 . The coach talk section  540  may therefore provide motivation, point out a particular area of focus, or otherwise provide guidance to the athlete  100  related to the ultimate goal of their particular plan or workout. 
         [0183]    In one embodiment, front page includes a plan tracker  532  section. The plan tracker  532  may graphically display an individual&#39;s  100  planned workouts, the number of planned workouts completed, and the number of planned workouts remaining to be completed. The plan tracker  532  may provide indication(s) about whether the individual  100  is meeting the specified goals for the completed workouts. 
         [0184]    The particular information displayed in the plan tracker  532  section may be set by the system or customized by the user  100 . Various information may be added or removed by the user  100  as desired. A user  100  engaged in multiple plans simultaneously (e.g. a running based plan and a non-running based plan) may choose to display multiple plan trackers  532  at once. In an embodiment, other trackers may be provided that display information similarly to the plan tracker  532 . For example, an athlete with a goal to lose weight may chose to display a weight tracker that tracks their progress towards a weight loss goal. 
         [0185]    The track module  500  may also support a message sub-module  528 .  FIG. 37  is an exemplary GUI window that may be displayed by the message sub-module  528 . The message sub-module GUIs may have the general look and functionality of an email application such as Windows Mail or Gmail. In an embodiment, the message sub-module may be linked to one or more email addresses. The email addresses may include an email address specifically associated with the user&#39;s  100  fitness monitoring system or general purpose email accounts provided by other providers. 
         [0186]    At least some of the messages received by the user  100  via the message sub-module  528  may be automatically generated by the server  112 . Messages may, for example, congratulate the athlete  100  for achieving certain training milestones or personal bests, may provide motivation or other training advice to the athlete  100 , may provide new product or service updates and/or downloads, and may include other things such as birthday or holiday greetings. 
         [0187]    As indicated above, the menu bar  204  may include several icons or indicia corresponding to the support  600 , library  700 , and forum  800  modules. 
         [0188]    The support module  600  may support help  602  and settings  604  sub-modules.  FIG. 39  is an exemplary GUI window that may be displayed by the help sub-module  602 . The help sub-module  602  may contain general information about the fitness monitoring system of the present invention, including a brief description of the system, its intended users, and the potential benefits available to those users The help sub-module  602  may provide a description of the various functions of the interactive website supported by the software and the underlying modules, sub-modules, and wizards. 
         [0189]    The settings sub-module  604  may be able of displaying GUI windows for collecting, storing, and reviewing personal settings  606 , workout settings  608 , device settings  610 , and privacy settings  612 . 
         [0190]      FIG. 40  is an exemplary GUI window that may be displayed by the settings sub-module  604  for collecting personal settings  606  information. Personal settings  606  information may include, for example, name, address, email address, password, gender, birth date, and address information. This information may be used to associate a specific user  100  with a particular user account. In an embodiment, some of this information may be used to tailor aspects of the portable fitness monitoring system to the user  100 , or to provide messages, product offers, or other items of interest to the user  100 . 
         [0191]      FIG. 41  is an exemplary GUI window that may be displayed by the settings sub-module  604  for collecting workout settings  608  information. Workout settings  608  information may include preferences such as preferred distance units (miles vs. kilometers), height units (feet and inches vs. meters and centemeters), weight units (pounds vs. kilograms), time format (12 hour clock vs. 24 hour clock), and a preferred week start date (e.g. Sunday or Monday). Workout settings  608  information may also include fitness profile information such as the user&#39;s weight, height, and maximum heart rate (if known). In one embodiment, the user may be periodically prompted by the system to update their fitness profile information. 
         [0192]    The workout settings page may graphically and/or numerically display the user&#39;s  100  current zone ranges according to the color-coded heart rate zone system described above. In an embodiment, the user  100  may be able to configure and customize heart rate, pace, or other custom workout interval settings via the workout settings page. 
         [0193]      FIG. 42  is an exemplary GUI window that may be displayed by the settings sub-module  604  for collecting device settings  610  information. Device settings information may include settings for any peripheral devices the user  100  has and is using in conjunction with the system of the present invention. These devices may include, for example, the devices discussed above with respect to  FIG. 11 , including mobile fitness phones, dedicated portable fitness monitoring devices, non-dedicated portable fitness monitoring devices, sports mode-enabled MP3 players, sports-enabled dongles, sports watches, display devices, and sensors (e.g. pedometers or heart rate sensors). The user may indicate which, if any, sensors they may use during their workouts. 
         [0194]    For example, via the settings page, the user  100  may be able to adjust the audio feedback options provided by their portable device(s) during a workout. In one embodiment, the user may select audio feedback with different types or styles of voices such as, for example, voices of different gendered speakers, voices with different accents, voices in different languages, voices from celebrities or fictional characters, and voices of different tones (e.g. supportive, calming, energizing, or stern). In another embodiment, the user may select specific performance parameter measurements to be recited via audio feedback during the workout. For example, a user may choose to have their elapsed time, calories burned, and distance traveled so far announced to them at regular intervals, on demand, or at predetermined times throughout the workout. 
         [0195]      FIG. 43  is an exemplary GUI window that may be displayed by the settings sub-module  604  for collecting privacy settings  612  information. Privacy settings  612  information may include, for example, whether the user&#39;s  100  profile and/or history are accessible to all users  100  or only select users  100 . For those users  100  with access, the privacy settings  612  may control specifically what historical workout information is accessible (e.g. only workout data from the last workout vs. all workout data). 
         [0196]    The privacy settings page may also allow the user  100  to link their fitness monitoring account to a social networking site, such as, for example, Facebook, MySpace, Twitter, Friendster, LinkedIn, or the like. Users  100  who link their profile to a social networking site may be able to specify how often their fitness information is updated to their social networking site and specifically what type of information is provided. 
         [0197]    The library module  700  may be capable of displaying GUI windows for videos  702  and articles  704 . The videos  702  and articles  704  may provide the user  100  with additional resources for planning, preparing for, an executing their workouts. 
         [0198]      FIG. 44  is an exemplary GUI window that may be displayed by the library module  700  for providing videos  702 . The library module  700  may include a videos  702  section that provides short animations and/or videos teaching the user  100  proper stretching, warm-up, cool-down, and other exercising techniques. The user  100  may select a video  702  icon with their cursor  206  to display the video  702 . 
         [0199]      FIG. 45  is an exemplary GUI pop-up window that may appear in response to the user  100  selecting a particular video. The pop-up window may include the animation and/or video, a suggested number or time period for the activity, and other notes or comments about the activity.

This may allow the athlete  100  to view instructions regarding preparing for or executing their workouts at the site of their workout prior to or during their exercise routine. 
         [0201]      FIG. 46  is an exemplary GUI window that may be displayed by the library module  700  for providing articles  704 . The library module  700  may include an articles  704  section that provides articles information the user  100  about various health and fitness topics. Articles may focus on topics such as strength training, cardiovascular exercise, biking, running, or a variety of other topics. The articles  704  may not all relate directly to fitness activities. For example, some articles may be related to diet and nutrition. 
         [0202]    The forum module  800  may be capable of displaying GUI windows for user forums. In one embodiment, as illustrated in  FIG. 47 , the forum module  800  may employ a social networking application, such as, for example, Facebook. The social networking application may utilize an application programming interface that allows the social networking application, such as Facebook, to be embedded into the GUI windows of the present invention. In another embodiment, the social networking site provides a feed that can be transmitted and displayed via the GUI windows of the present invention. 
         [0203]    The forum page may be a place where users  100  can exchange updates regarding their fitness planning and progress using the system of the present invention. Users  100  may also exchange information regarding the website, the particular training equipment and devices they are using, the athletic events or races they are participating in, and information giving and/or requesting coaching or other advice. 
         [0204]    Various aspects of the present invention, or any parts or functions thereof, may be implemented using hardware, software, firmware, tangible computer readable or computer usable storage media having instructions stored thereon, or a combination thereof and may be implemented in one or more computer systems or other processing systems. 
         [0205]    Program products, methods, and systems for providing fitness monitoring services of the present invention can include any software application executed by one or more computing devices. A computing device can be any type of computing device having one or more processors. For example, a computing device can be a workstation, mobile device (e.g., a mobile phone, personal digital assistant, or laptop), computer, server, compute cluster, server farm, game console, set-top box, kiosk, embedded system, a gym machine, a retail system or other device having at least one processor and memory. Embodiments of the present invention may be software executed by a processor, firmware, hardware or any combination thereof in a computing device. 
         [0206]    Software of the present invention may be stored on any computer-usable medium. Such software, when executed in one or more data processing device, causes the data processing device to operate as described herein. Embodiments of the invention employ any computer-usable or -readable medium, known now or in the future. Examples of computer-usable mediums include, but are not limited to, primary storage devices (e.g., any type of random access memory), secondary storage devices (e.g., hard drives, floppy disks, CD ROMS, ZIP disks, tapes, magnetic storage devices, optical storage devices, MEMS, nanotechnological storage devices, etc.), and communication mediums (e.g., wired and wireless communications networks, local area networks, wide area networks, intranets, etc.). 
         [0207]    While many of the exemplary embodiments discussed above make reference to a color-coded heart rate zone-based system, color-coded zone systems based on zones of other parameters including, but not limited to, speed, pace, stride rate, calories, respiration rate, blood oxygen level, blood flow, hydration status, or body temperature may also be employed. The present invention is therefore not to be limited to only heart rate based zone systems. 
         [0208]    Furthermore, while many of the exemplary embodiments discussed above make reference to a color-coded heart rate zone-based system where the zones may be defined as ranges of percentages of an athlete&#39;s  100  maximum heart rate, heart rate zones may be defined based on other parameters as well. 
         [0209]    In one embodiment, heart rate zones may be defined as ranges of percentages of an athlete&#39;s  100  maximum heart rate. In another embodiment, heart rate zones may be defined as ranges derived from parameters such as an athlete&#39;s  100  ventilation threshold heart rate. In a further embodiment, heart rate zones may be defined as ranges derived from both the athlete&#39;s  100  peak heart rate and the athlete&#39;s  100  ventilation threshold heart rate. 
         [0210]    An athlete&#39;s  100  peak heart rate may or may not be the same as the athlete&#39;s  100  maximum heart rate. As used herein, “peak heart rate” refers to the highest heart rate that a particular athlete  100  can achieve during a training session. The athlete&#39;s physiologically possible maximum heart rate may be higher that the peak heart rate. For some athletes  100 , typically those in top physical condition, their peak heart rate may be very close to their max heart rate. For other athletes  100 , typically those who are less well conditioned, their peak heart rate may be far less than their true physiologically possible max heart rate. Accordingly, in an embodiment, an athlete  100  may enter their peak heart rate into their portable fitness monitoring device  102  or save this information on the server  112 . The athlete  100  may also be able to capture peak heart rate information during an assessment run, as described in further detail above. 
         [0211]    As an exercise progressively increases in intensity, the air into and out of your respiratory tract (called ventilation) increases linearly or similarly. As the intensity of exercise continues to increase, there becomes a point at which ventilation starts to increase in a non-linear fashion. This point where ventilation deviates from the progressive linear increase is called the “ventilation threshold.” The ventilation threshold is closely related to the lactate threshold, or the point during intense exercise at which there is an abrupt increase in blood lactate levels. Research suggests that the ventilation and lactate thresholds may be some of the best and most consistent predictors of performance in endurance events. The athlete&#39;s  100  heart rate at the ventilation threshold point may be referred to as their ventilation threshold heart rate. Accordingly, in an embodiment, an athlete  100  may enter their ventilation threshold heart rate into their portable fitness monitoring device  102  or save this information on the server  112 . The athlete  100  may also be able to capture ventilation threshold heart rate information during an assessment run, as described in further detail above, by using equipment necessary for determining ventilation and/or lactate threshold. 
         [0212]    In an embodiment, the heart rate zones may be defined as ranges derived from both the athlete&#39;s  100  peak heart rate and the athlete&#39;s  100  ventilation threshold heart rate. For example, Table 1 illustrates an exemplary embodiment in which color-coded heart rate zones may be defined for an athlete  100  with a peak heart rate (PHR) of 200 beats per minute and a ventilation threshold heart rate (VTHR) of 170 beats per minute:

         [0213]    As illustrated by Table 1, each color coded zone may be defined as having upper and lower limits. Each zone limit may be calculated based on PHR, VTHR, and/or one of the other zone limits. A heart rate value associated with each zone limit may be correlated to a percentage of max heart rate if max heart rate is known or can be estimated. In an embodiment, PHR is assumed to be 93.5% of an athlete&#39;s  100  max heart rate value. Accordingly, physical activities may be carried out and content may be presented via GUIs according to the color-coded heart rate zone based system of the present invention. 
         [0214]    As described above, color-coded pace or speed based systems may also be employed. In an embodiment, upper and lower pace or speed zone limits may be derived in part from PHR and VTHR values. For example, an athlete may conduct one or more physical activities using a heart rate monitor, a ventilation threshold (or lactate threshold) monitor, and/or pace or speed monitors. Measurements may be conducted by portable monitors, stationary monitors, or in a laboratory after the physical activities are conducted. A relationship between the pace or speed of the athlete and max heart rate, PHR, and/or VTHR may be established. Accordingly, color-coded pace or speed zone limits may be determined based on this information. 
         [0215]    In another embodiment of the present invention, zones may be determined based on a measurement of power. Power measurements may be derived from pace calculations if other parameters such as, for example, the athlete&#39;s  100  body weight and the incline of the surface traversed (e.g. incline of a sidewalk, bike path, or treadmill surface). 
         [0216]    In an embodiment, the athlete  100  may be able to download mobile applications to a mobile device such as a mobile phone, that are capable of presenting GUIs similar to those illustrated herein, from server  112 . Accordingly, the athlete  100  may be able to interact with the server  112 , access their account, and perform many of the other planning, tracking, and other functions described herein from a mobile device. 
         [0217]    The present invention has been described above by way of exemplary embodiments. Accordingly, the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalences.
