Avoiding Dogs   (Arnie Berger  arnie@hp-lsd.COL.HP.COM)
[Ed. note: Originally posted to rec.bicycles - but it applies here as well]

  There are varying degrees of defense against dogs.

  1- Shout "NO!" as loud and authoritatively as you can. That works more
     than half the time against most dogs that consider chasing you just
     good sport.

  2- Get away from their territory as fast as you can.

  3- A water bottle squirt sometimes startles them.

  If they're waiting for you in the road and all you can see are teeth
  then you in a heap o' trouble. In those situations, I've turned around,
  slowly, not staring at the dog, and rode away.

  "Halt" works pretty well, and I've used it at times. It's range is about 8
   feet.

   I bought a "DAZER", from Heathkit. Its a small ultrasonic sound generator
   that you point at the dog. My wife and I were tandeming on a back road and
   used it on a mildly aggressive German Shephard. It seemed to cause the
   dog to back off.

   By far, without a doubt, hands down winner, is a squirt bottle full of
   reagent grade ammonia, fresh out of the jug. The kind that fumes when
   you remove the cap. When I lived in Illinois I had a big, mean dog that
   put its cross-hairs on my leg whenever I went by. After talking to the
   owner (redneck), I bought a handlebar mount for a water bottle and loaded
   it with a lab squirt bottle of the above mentioned fluid. Just as the
   dog came alongside, I squirted him on his nose, eyes and mouth. The dog
   stopped dead in his tracks and started to roll around in the street.
   Although I continued to see that dog on my way to and from work, he
   never bothered me again.

   Finally, you can usually intimidate the most aggressive dog if there are
   more than one of you. Stopping, *and moving towards it will often
   cause it to back off*. ( But not always ). My bottom line is to always
   *run* routes that I'm not familiar with, with someone else.

   As last resort, a nice compact, snubbed nose .25 caliber pistol will fit
   comfortably in your jersey pocket. :-)

Clothes (Winter/Summer) (Mike Gilson GILSON@ALF.CS.HH.AB.COM)

Disclaimer
----------
Preference on the amount of clothing required for winter
running varies widely between individuals.  There are a
couple of runners that I see that wear shorts, long sleeved
T-shirt and gloves at 30F!  So expect to experiment with
how much clothing at various temp's.

Second: I don't have any interest in the type of clothes
you buy/wear; I neither make nor lose money by your choices.
What I have to say here is *my* opinion only.

Rules for Winter Running
------------------------
The first rule is to dress in layers.  Outer layers can be
added/shed easily.

The second rule is to stay dry.  When your clothes get wet,
they get very heavy - heavy enough to degrade performance -
and you get cold.

The final rule is to hydrate.  You may not sweat as much, but
you still need to take in fluids.

Clothing Layers
---------------
Inner layer.  The layer closest to the skin should be a
tight, lightweight fabric that wicks water away from the
skin.  Shirts should be long-sleeved, skin-tight (without
chafing), and may be turtle-necked (my preference).  There
are a variety of fabrics that are effective in wicking water;
I have had a lot of success with polypro, but it is not
machine washable.  These are readily available at running
specialty shops and mail order.  For pants, lycra running
tights work very well.

Outer layer.  The next layer should be a looser, mediumweight
fabric that wicks water.  A zipper at the neck is convenient
for temperature control.  I prefer a shirt that is slightly
longer than waist-length so that I have the option of tucking
it into the pants.  I've had more success in finding these
in cycling stores than anywhere else.  Two layers of lycra
tights work if it's really cold.

Shell.  A water-proof or water resistant shell that is
breathable is useful in the coldest conditions.  These are
usually sold as suits, but tops are available separately
at a higher cost (relatively speaking).  Gore-tex is
considered by many to be the best fabric, but there are
cheaper alternatives.  You can get these suits made to your
measurements or buy them off the rack.  I have a Burley
jacket, which I purchased at a cycling shop.  It's chief
advantage over the running suits is the venting and extra
zippers for temperature control.  There are zippers under
each arm, starting at mid chest going up to the armpit and
travelling down the arm to about mid forearm.

Tights.  Tights have been mentioned above as inner/outer layers.
Many people run in sweats, but sweats have two disadvantages:
they're heavy and they get heavier when wet.  Lycra is
lightweight and warm, but costs more and shows off body
(im)perfections more than sweats.

Gloves.  Any cotton glove works.

Hat.  A lot of heat is lost through the scalp, so a hat
is a must for most people.  Cotton hats get too heavy
with sweat.  Balaclavas are more versatile than hats,
and allow you to cover you neck/face if requires.  Both
hats and balaclavas are available in wicking fabrics.

Socks.  A wicking sock will seem less heavy and your feet
will be drier than a conventional sock.  Coolmax socks are
my preference, worn in a single layer.  You can also find
other fabrics, such as capilene or polypro socks, which are
considerably more expensive.

Running shoes.  Runner's World (anyone know which issue?) had
some tips from Alaskan runners on how to put (short) screws
into the sole of the shoe for better traction on the ice.
I haven't tried it, but you obviously have to be careful not
to puncture the midsole, air/gel chambers, etc.

Clothing materials  (Jim Carson  carson@mu.rice.edu)
[Ed note: From a summary Jim posted]

Polarlite
  Fluffy, fleecy stuff also called Polarplus and Synchilla.  Comfortable.
  Incredibly warm, especially under something that breaks the wind.
  Doesn't wick moisture out very well.  Breathes very well.

Supplex (nylon)
  Comfortable.  It is breathable and water repellent (but NOT water proof).
  Seems to absorb a small amount of water if it is really getting drenched

Merino (wool)
  From a "breed of fine-wooled white sheep originating in Spain and producing
  a heavy fleece of exceptional quality."  I guess you could treat this as
  normal 100% wool.

Thermax
  An improvement on Polypro.  The big advantage is heat resistance so
  you can put it in the dryer.  Balance that against the extra cost.

CoolMax
  This stuff seems more like a plastic bag than the revolutionary wicking
  material it is advertised as.

Dacron
  Trademark name for Dupont polyester.  Woven fabric made from dacron is
  similar to nylon ripstop or taffeta, but not as stretchy.  Many of the
  better clothing insulations are made from dacron.  They are usually refered
  to by more specific trademark names, like quallofil, hollofil, polarguard,
  and dacron-88.

Lycra
  Used for its stretch, mostly a warm weather (>65 degrees) thing.

GoreTex
  A teflon based membrane with microscopic holes.  Gortex's claim to
  fame is that it will let water vapor (from perspiration) through, but
  not liquid water (rain).  It blocks wind fairly well too.  The
  membrane is delicate, so it always comes laminated between 2 layers of
  other material.  It does not breathe enough.  There are less expensive
  alternatives.

Polypropylene
  Does not wick very well.  Can be uncomfortable.  Troublesome to
  care for (e.g. can pill badly)  Will keep you fairly warm if soaked.
  Not very wind resistant.  Melts in the dryer.

Capilene
  Wicks moisture away.  Very comfortable.  Comes in different weights
  for more/less warmth.  [lots of favorable things about it... only
  really unfavorable thing is the co$t]

60/40 cloth -
  This is a cloth with nylon threads running one direction, cotton in
  the other. It was the standard wind parka material before Goretex came
  along, and is considerably less expensive.  Good wind resistance,
  fairly breathable.  Somewhat water resistant, especially if you spray
  it with Scotchguard, but won't hold up to a heavy rain.

Dead Runners Society   (Christopher Mark Conn sascmc@UNX.SAS.COM)

The Dead Runners Society is a discussion group for people who like to
talk about running. The group is very informal and social and we all
try to encourage each other in our running programs. We talk about
everything related to running, from meditation to marathons. We
currently have about 300 members around the world. To join send email

Terminology

Pronation/Supination (Thomas Page page@ficus.cs.ucla.edu)

      "Over" pronation describes a minor misalignment of the leg's 
       forward swing that causes the footstrike to be skewed 
       to the inside of the heel. (Jim Horalek)

      "Over" supination is the reverse - impact is shifted toward 
       the outside of the heel. (Jim Horalek)

Pronation and supination describe natural and normal motions of the
foot during the walking or running stride.  In a normal stride, the
outside portion of the heal strikes the ground first.  The foot
pronates to absorbe shock.  That is, it rolls inward.  At the end of
the stride, the foot re-supinates -- rolls outward-- on push-off.

What the previous writer (Jim Horalek horalek@alliant.com) is defining
is `over pronation', and `over supination'.  These are excesses of the
normal motions.  Note that over pronation is fairly common and many
shoes are designed to counteract this.  Over supination is very rare.
Most people who think they over supinate probably just under pronate.
Some people who think they over pronate may in fact pronate a normal
amount, but fail to re-supinate sufficiently at the end of the stride.

Fat burning primer (Ramesh K. Sitaraman rks@phoenix.princeton.edu)
                   (Thomas Page page@ficus.cs.ucla.edu)

There seems to be a lot of debate and a few misconceptions about Fat
burning, Stamina etc. Here are a few basics. They are based on
standard scientific sources.

1. There are 3 sources of energy : Muscle glycogen, Liver Glycogen,
Fat (triglycerides). There is also blood glycogen, which is what the
brain runss off.

2. During excercise the glucose and fatty acid in the blood is
utilised.  Fatty acid in blood stream is utilised in preference to
glucose for various reasons. (There are organs like the brain that can
use only one energy source : glucose).

Tom: Muscle glycogen is used before blood or liver glycogen.  When you
carbo load before a race, you are packing in the muscle glycogen.  You
only have a few minutes supply of blood glycogen once you start using
that for running.

3. Then why can't we run on fat FOREVER ??? Because the fatty acid
concentration in blood can never be much. In fact, it seldom exceeds
(in Molars) the concentration of Glucose !!! Why this "transportation
problem" for fats ?? There ain't much Albumin to transport the fat and
fat in excess in blood stream will deposit on viens constrict and more
directly cause blood clots and kill you !!!

Tom: Noakes' book "Lore of Running" phrases it as "fat burns in a
glycogen flame."  Even a lean marathoner has a virtually unlimited
supply of fat.  But you are limited in your ability to mobilize the
fat from the stores (fat deposits you know where), and you have the
limited amount of glycogen needed to burn along with the fat.

4. As you workout aerobically, the fat acids start increasing in
concentration in the blood stream. SO LONGER YOU WORK OUT THE GREATER
PERCENTAGE OF WHAT YOU BURN IS FAT ! But remmeber that the fat
concentration cannot go up too much. Only about 50 percent of your
energy can come from fat.

5. So what happens if I run out of glucose ? Can I run on fat ?  Very
Very painfully perhaps. Your rate of glycogen usage is a complex
function of your running efficiency, what percentage of VO2max you run
(typically 85% for an all out marathon), what your VO2max is, how much
glycogen you are able to store in your muscles, your state of fitness,
etc.

6. Only long sustained exercise ( 30 -40 mins) is guaranteed to burn
fat (see fat mobilisation etc above). 

Tom: During the first 10 minutes of exercise, you burn almost
exclusively glycogen.  From 10-30 minutes, you gradually increase the
percentage of energy from fat, and hit a plateau between 30 and 40.
So, keep running beyond 30-40 and you will keep burning a maximum
amount of fat.  The real magic of the 30-40 minute range is that if
you stop running there, you will continue to burn a large percentage
of fat, for several hours.

7. Some person said doing exercise with breaks as being better for
burning fat. Not true. Neither does it build stamina.  (Doing
intervals to build stamina is fine. But it should not constitute more
than small fraction of your total excercise duration. Most of it
should be of the long continous endurance building type.)

Tom: For the reason stated above, taking short breaks will not cause
you to stop burning fat.  If by taking walking breaks in the middle of
your long runs you can keep going significantly longer, then taking
walking breaks will increase the fat you burn.  Also, if you are
training for a marathon, you need to get in those 3+ hour runs.  If
you need a couple of walking breaks to keep going that long, you are
better off taking them than quitting at 16 miles.  Of course, if you
can't run continuously for 3+ hours what you are concerned about is
finishing the marathon, not racing it fast, so by all means take
walking breaks.  If you want to get fast, train until you don't have
to walk.

Fluid replacement (2 personal methods)

As an ultramarathoner, trail runner fluid replenishment etc. is quite
important. My findings, based on personal experience, is that in 90+
degree weather I use a liter per hour on a one hour run - and that is
carrying the water with me.  If you are not running enough distance,
dont be concerned about energy type drinks, and you probably don't
lose enough salts to need electrolytes.  But your system will absorb
more fluid faster is it is hypotonic and cool. If you guys are always
running for 45 minutes or an hour in HOT weather - I would really
suggest carrying water.  When you realize your dehydrated its TOO late
- and it takes longer to replenish fluids than it does to lose them.
(Milt Schol milts@mse.cse.ogi.edu)

I prepare for a run with about 24-30 ounces of lukewarm water within 3
hours of the run. As for after the run, if it was particularly
strenuous (and in the 85+ and humid Pittsburgh weather of late, the
runs have been strenuous for me), within 10-15 minutes following the
run, I take ~10-15 ounces of room-temperature, diluted Exceed (about 2
parts Exceed to 3 parts water). I follow that with about 24-30 ounces
of room-temperature water over the next hour or two. (Barbara Zayas

Second Wind (Newsweek July 27, '92 Reproduced without permission)

If an Olympian experiences a second wind, it's probably a sign that he
isn't in a great shape. Scientists are divided over whether a second
wind is purely psychological - the athlete "willing" himself forward.
But if it has a physical basis too, the sudden feeling of "I can do
it!" right after "I want to die" probably reflects a change in
metabolism. The body gets energy by breaking down glucose, which is
stored in muscles. This reaction releases lactic acid, which the body
must burn in order to prevent a lactic-acid buildup that causes
cramps. Burning lactic acid requires oxygen. If the body does not
breathe in enough oxygen; the runner experiences oxygen debt: the
heart beats more quickly; the lungs gasp; the legs slow. The second
wind, says physicist Peter Brancazio of Brooklyn College, may come
when the body finally balances the amount of oxygen coming in with
that needed to burn the lactic acid. (When burned, lactic acid is
transformed into sweat and carbon dioxide.) Why doesn't everybody get
a second wind? Couch potatoes don't push themselves past oxygen debt;
true Olympians have enough lung capacity and cardiovascular fitness to
avoid oxygen debt in the first place.

Soda Pop (Paulette Leeper pleeper@wtcp.DaytonOH.NCR.COM)

Q: Does anyone have any opinions on Soda pop as a drink in General.

I find the CAFFEINE in soda to be irritating and DEHYDRATING, so,
IMHO, drinking soda with caffeine (regardless of whether or not it
contains sugar or aspartame) defeats the purpose of quenching thirst.
It's much like drinking beer to quench thirst...  it FEELS good, and
TASTES good, but as a mechanism for hydration, it does the exact
opposite.

Hashing

From: Dweezil the Butt Beaker <daveo@theopolis.orl.mmc.COM>
Subject: Rules of Hashing (one version, re: Rule Six)
Organization: Orlando Hash House Harriers

X-Hhh: A Drinking Club With A Running Problem.
X-Hhh-Motto: If you have half a mind to hash, that's all you need.
X-Hhh-Philosophy: Carpe Cerevisiam
X-Oh3-Motto: We get drunk, we get naked, we give hashing a bad name.
X-O2H3-Motto: We have beer, we have cookies, we give hashing a nice name.
X-Dbh3-Motto: Daytona Beach Hash House Harriers never run out of beer.
X-Dbh3-Motto: We have beer before, during, and after the hash.

The Hash House Harriers is a running/drinking/social club which was
started by bored expatriates in Kuala Lumpuer, Malaysia in 1938.
("Hash House" is the nickname of the restaurant/bar to which they
retired for food and beer after a run.)  Hashing is based on the
English schoolboy game of "Hare and Hounds"; a Hash is a
non-competitive cross-country run set by one or more runners called
hares.  The hares run out in advance of the other runners (the pack of
hounds), and set a course marked by white flour, toilet paper, and/or
chalk marks.

Hash Rules
----------

1. A HASHMARK is a splash of flour used to mark the trail.  The pack
should call out "On-On" when they see a hashmark.  Blasts on horns,
whistles, and other noise makers are encouraged.  Hounds asking "RU?"
(are you on trail?) of the FRB's (Front-Running Bastards) should be
answered "On-On", which means they are on trail, or "Looking", which
means they`ve lost the trail.

2. ARROWs, or several closely spaced hashmarks, are used to indicate
change of trail direction.  Hound should use arrows different from
those used by the hares as necessary to assist hounds further back in
the pack.

3. A CHECKMARK is a large circled X, or a circle with a dot at its
center (fondly known as a "Titty Check").  Checkmarks indicate that
the trail goes "SFP"; that is, the pack must search for true trail.
Hounds should call out "Checking" when they see a checkmark.
(Checking IS NOT Looking!)

4. A Backtrack is three lines chalked or drawn in flour across the
trail, indicating a false trail.  The pack, upon encountering a
backtrack, calls out "On-Back" or "Backtrack", and goes back to the
last checkmark to find true trail.  Sometimes a hound will draw an
arrow with a backtrack sign at the checkmark to identify the false
trail for the rest of the pack.

A CHECKBACK is a devious variation of the checkmark/backtrack.  A
checkback is a CB followed by a number.  For example, a "CB 5" means
to backtrack five hashmarks, then look for true trail as one would at
a check.  Also known as a COUNTBACK.

A WHICHWAY is two arrows, only one of which points toward true trail;
no hashmarks will be found in the other direction.

5. Tradition requires a DOWN-DOWN (chug-a-lug) of a beer after a
hasher's virgin hash, naming hash, and other significant occasions,
e.g., 25th hash, 50th hash, etc.  A Down-Down is also in order for
hares, visitors, and for any other reason that can be thought up.
While frowned upon as "alcohol abuse", it is permissible for non-
drinkers to pour the beer over their head; a soda Down-Down may also
be elected.  The primary consideration of the Down-Down is that once
the mug leaves the drinker's lips, it is turned upside-down over the
head.

6. THERE ARE NO RULES.

===========================================================================
Interval training (micbrian@ubvmsb.cc.buffalo.edu)

First off, keep in mind that the interval part of the run is the rest
part.  This is where your body recovers and strengthens itself.

Secondly, say your goal is to run an 8 minute/mile 10k.  Start your
intervals by doing 5X400m at a little under 2 minutes per rep.  You'll
see that an 8min mile is a 2min 400, so to better that, you run a
little faster, as I said.  Walk or jog between the rep (this is the
interval).  Remember to keep with what you started at.  If you jogged
to rest, don't walk during the next interval.

Intervals should be challenging, but not defeating.  If you are having
problems maintaining your form during the course of the whole run, you
are doing too much.  You should feel good at the end of your run, not
ready to drop dead.

Remember to warmup and cool down sufficiently before and after
intervals.  10 minutes of jogging is suggested.

Other things to remember: you can customize intervals to achieve
different things.  For example, to increase endurance, you can
decrease your interval while running the same rep.  Or you can
increase the rep and still do the same interval.  You can work on
speed by running faster reps.  There are other variations as well, but
I don't remember all of them.

Lastly, make sure you have a good aerobic base when you start, and
don't do too much too fast.  You can tire your muscles out, and it
will take a while to recover.

Your goal is to exercise your fast twitch muscles, those used for
speed.  I've been doing intervals for about 2 months now, and it has
made a difference.  The first race I ran after starting intervals, my
time dropped by about 15 seconds.  I have a race tomorrow, and am
hoping to improve on that.  I also notice I have more pep in my
regular workouts.  I get out there, and once I'm warmed up, my body
wants to run fast.

Legs

Sore knees (Elizabeth Doucette ead@tmsoft.uucp)

When running (also walking, and cycling), the inner most quad. muscle
(inner part of thigh) does not get exercised as much as the other
three quad. muscles of the thigh.  If this inner muscle isn't
strengthened by specific exercises, an imbalance of the muscles may
occur.  This can cause irritation of the underside of the kneecap
(chondromalacia patellae) because the imbalance of the muscles can
pull the kneecap towards the outside of the leg.

I believe there is a groove in the underside of the kneecap that rides
on a ridge of bone in the knee.  If the kneecap is pulled to the
outside of the leg, the groove will want to move in a slightly
different direction than the ridge of bone.  This can cause the groove
to become irritated.

I had chondromalacia patellae for a long time (and many of my running
friends did too) but I haven't had problems since I've been doing
specific exercises for my inner quad. muscle.  It is tedious and
boring but it works.  I haven't had knee problems for about 3 years
now :-).  I should do this every day, whether I work out or not, but I
don't always.  If I feel any discomfort at all in my knees, I make
sure I'm more diligent with this exercise and the discomfort always
disappears.  I'm always able to prevent a problem now.

The exercise is just a leg raise with the foot flexed and pointing
away from the body.  With this exercise make sure that your back is
supported.  As your quad. muscles fatigue, there is a tendency to help
out with your back muscles.  You may not realize that you're doing
this until you notice later that your back is a little sore.

Sitting on the floor, bend one leg (like you're going to do a sit-up),
bringing the knee towards the chest.  The other leg is straight. Place
your hands behind you on the floor to support your back.  You can vary
this by leaning against a wall and hugging your knee to your chest
with both arms.  YOUR CANNOT BE TOO CAREFUL WITH YOUR BACK.

For ease of explanation, start with your right leg being straight and
flex your foot (bring your toes towards your head, as opposed to
pointing them away from you).  Turn your leg to the right, so that
your toes and knee are pointing to the right as far as possible.  The
position of the foot is important because it helps to isolate the
inner quad. muscle.  Now, do leg raises.  When I started I could only
do 10 or 20 before I needed to rest.  Don't do the leg raises too
quickly because technique is more important than speed.  I now do
three sets, each leg of 60 repetitions (alternating legs after each
set) for a total of 180 per leg.  It takes me about 10 minutes.

You can tell if your muscle is getting fatigued because it will start
to quiver.  Don't push it, change legs.  Keep note of how many
repetitions you do before you get fatigued and try to increase the
repetitions next time.  Compare you to you, not to others.

Leg presses used to bother my knees.  Now that I'm doing leg raises,
the leg press doesn't bother me any more.  Technique is important when
doing leg presses.  (Technique is probably more important than the
fact that I'm doing leg raises).  Make sure that the seat is forward
far enough, so that when you press you cannot lock your knee.  This
makes the initial position feel too cramped.  My knees feel too close
to my chest.  But it works for me and for others (both men and women)
that I work out with.  Nautilus equipment uses a cam system, such that
there is less resistance on your knees in the initial, starting
position, so there is less chance of injury.
