Dear Coach: I started power walking this spring and
within eight
weeks moved up to jogging. I cannot believe how much I enjoy
running. I now run three miles several times per week as well as
one six-mile run. I am concerned about whether it is safe to run
outdoors in the cold weather, particularly when the wind chill
is below zero. DarleneDear Darlene: First, let me congratulate you on becoming
a
runner and discovering the joy of running. It is perfectly safe
to run through the winter as long as you take a few precautions.
There is no danger to your lungs because the cold air you
breathe
is warmed by the time it gets into your lungs. You need to wear
proper running attire. I recommend that you go to one of the
area's running specialty stores where they can help you figure
out the proper gear. You want to run with light layers of
clothes that breathe instead of running with bulky sweat
clothes. When running in very cold weather, try to run into the
wind at the beginning and end your run with a tailwind. If it is
really windy and cold, I put Vaseline
on my face to protect it. If you start out with a tailwind, you
will overheat and be chilled when you turn around and head back
into the wind. Also, be very careful of your footing if there is
any ice or snow on the ground--if there is, shorten your stride
and take short, choppy steps. Be particularly careful if you are
an early morning runner like me because it is hard to see
slippery patches of ice. Finally, keep in mind that the first
four to five minutes in cold weather is uncomfortable but once
you get going, you will be plenty warm.
Dear Coach: I want to start doing speed work to prepare
for 10K
races this spring. Because I do not have a heart monitor, please
tell me how fast I should be doing mile, 800, and 400 repeats.
Mark
Dear Mark: You should do your mile repeats at ten-mile
pace.
This will be a few seconds per mile slower than your current 10K
race pace. On a heart monitor, this translates to 80 to 85
percent effort. You should jog at most one lap before starting
your next mile repeat. Your 800-meter repeats should be run at
approximately 5K race pace with a recovery of 200 to 400 meters.
Your 400-meter repeats should be three to five seconds per lap
faster than your 800s with a 200-meter recovery. While you
probably can run these workouts faster, the point of them is to
concentrate on form and to be relaxed. If you find that you need
a longer recovery, chances are that you are running them too
hard.
Dear Coach: My maximum heart rate is 182 and my resting
heart
rate is 42. You have stated that I should do my easy runs at 60
to 70 percent effort, which I figure is 109 to 127. I am barely
running at 127 and at 109 feel like I am crawling. Rick
Dear Rick: You have to factor in your resting heart rate.
My 60 to 70
percent effort is based on the Karvonen formula that works as
follows: [(Max heart rate minus resting heart rate) times 60%]
plus [Resting hearting rate] = percentage. In your case, it is
182 minus 42 or 140 times 60%, which is 84 and adding back 42
makes 60% equal to 126. Similarly, 70% will be 140. I think you
will find that running between 126 and 140 will result in an
easy conversational pace. For those with a scientific bent, the
Karvonen formula approximates percentage of VO2 max.
Dear Coach: I have a friend who is trying to lose body
fat
through running. She wants to know whether running fast for a
short distance is better than running moderately for a longer
time. Jenni
Dear Jenni: She will be better off running more miles in
total.
After all, weight loss is, at least in part, a function of
burning calories. While running fast may burn off calories at a
faster rate, what matters is total calories burned and that is a
function of distance. Once she has developed an aerobic base by
running longer distances, then she may want to do one or two
shorter and harder runs each week. While I do not have any
scientific evidence of this, my own experience is that I tend to
lose more weight when doing intense workouts than when all my
running is easy. As stated above, however, the intense workouts
take place only after an adequate mileage base has been
established.
Coach West's Winter Tip
Winter running is a good time to
concentrate on building your mileage base. It is often hard to
find dry pavement or a clear track to do consistent speed work.
Use January and February to do lots of easy miles. It will help
your body recover from the stress of fall racing or a fall
marathon. You can pick up your speed work in March and be ready
to race in April and May.
