As we ran along I became engrossed in the conversation and totally forgot about checking my FS-1. It wasn t until we stopped at a water stop at 15 miles that I checked it. After each run, I am able to keep track of my run on the Internet via my PC using the Netlink device. At the push of a button, all the information stored in the FS-1 downloads automatically to my own personal running log located on the Fitsense website. This information includes distance, pace, running time, calories burned and heart rate throughout the run.
Heart rate is captured using the optional heart rate monitor.
The FS-1 also has many more nifty features including a log that displays data from the last 28 runs or data from the last 75 splits and the ability to set interval alerts and pace zones. The odometer mode allows you to display total distance and calories burned the date of the last reset. Additionally it can be used as a regular watch and has the standard alarm mode found on most digital watches. I can imagine lots of uses for the FS-1. It will make trail running a whole new experience and fartlek training can now be much more precise.
