steve said:I recently bought a Garmin Edge with a heart rate monitor. I have been
having fun using the virtual training partner to motivate myself to
push hard. On a recent ride I did 14 miles at an average heart rate of
167 and hit a maximum of 179. I’m 57 years old and all the formulas
that I have seen put my maximum heart rate at ~163 to 170. I have been
running and biking my whole adult life so perhaps my max heart rate
should be a bit higher but I’m beginning to wonder if maybe I should
back off a little. During the ride I was at 90% of my max heart rate
(based on 174) for 35:30. As I understand it 90% is not supposed to be
sustainable. I was pushing very hard but I didn’t think I was maxed
out.
The fun data point is that I supposedly burned 1030 calories in 41
minutes.
Thanks for any thoughts

The only way to find your max HR is to measure it. There is too much
individual variation to make any formula particularly useful.
90% for 35 minutes is possible even for a FM, but it is very, very
hard and very unlikely in all but very motivated circumstances. This
indicates to me you are underestimating your max HR. And anyway there
is never any reason to back off from some number on a screen anyway.
Max HR I don' think is trainable, so previous riding and running
shouldn't make any difference.
A friend of mine got a Garmin early last year and has been using the
virtual partner stuff to race himself. He also does all sorts of other
things guided by the Garmin and has become monster strong. It has been
a great tool for him.
My theory of cycling gadgets is that they are sort of like computer
programming languages. People chose the ones they are comfortable
with, and sometimes weigh their decision on what the task is, but then
end result is a program that either sucks or doesn't, depending upon
how it was written, not what it was written in.
In other words, some people will train better with a Garmin, some with
a PowerTap, some with a Polar, some with nothing, etc. And it is the
quality of the training that dictates the outcome in terms of fitness
and speed. So if the Garmin is best for you to make your training
higher quality, have at it!
