The point of training is to build up your body to do better on race day. The point of racing is to
do the best you can do. These are different activities.
Training at too high a HR for too many days in a row will not make you better, and will lead to
overtraining. Your body builds up during rest, not during exercise. The point of the training is to
convince your body that it's time to build itself up.
I don't pretend to understand the physiology behind this, but I do know that it works. Very long
periods at moderate heart rate seems to build up the ability to tolerate the later hard interval
workouts. The interval workouts seem to build up the heart stroke volume & reduce the heart rate,
but you won't be able to tolerate them without a proper base of LSD (long slow distance).
You can accomplish a surprising amount of training with intervals at less than max effort. If you
think that you aren't working hard enough, then do more intervals, not greater effort.
I've always been told that even pace is better, and that's probably true for a race, but it doesn't
seem to be the case for training.
Re max heart rate: it doesn't seem to be the constant that some books would lead you to believe.
I've found that -- when rested for several days -- my max heart rate is 5-10 bpm higher than after
several days of hard workouts. The resting HR is also lower by several bpm.
Shayne Wissler said:I've just recently started working with a heart rate monitor. I bought a few books by Chris
Carmichael to help me figure out how to train with it, and one thing I've been surprised about is
the low intensity he recommends.
For example, I rode my favorite hill climb for the first time with my HRM, and noted that my heart
rate was 92-94% of max for an hour (occasionally it would dip down to about 88%). When Carmichael
was talking about improving LT during climbing, he was prescribing 78-83%, which is a far lower
effort for
me. The 92-94% range about puts me at my limit, and intuitively it seems like that would yeild
greater improvements, but I'm not the exercise physiologist. Is there something wrong with
training at my limit?
By the way, I measured my max on two separate occasions, so I'm pretty sure it's close to being
right. Plus it's quite a bit higher than the 220-age thing so I don't think I've underestimated it.
I'm 34 and the max I measured was 197.
