one for those who know more about training with HR and the implications than I do.
I know HR is said to be generally not reliable in the way that measured power is due to many many variables but this is something that for me is fairly consistent.
I'm (cough) 42 years old, and recently got back into 'training' with HR (OK measuring it when riding).
my base zone2 is around range of 125-135 and when doing what feel like all out intervals on the turbo I can get a max of 180bpm tops.
Now on a recent group ride on the road, which was about 4.5hours long, me putting in as much time on the front as most, I can see on the strava data that some guys who are at least 5 years older than me have both higher average HR for the ride and a max HR of 15-20bpm higher.
one guy who is about 10 years older has about the same average and max HR.
The thing is, I know those guys are a LOT fitter than me and would smash me up one-on-one, yet it looks like their HR is higher than it should be relative to mine, if that makes sense, partly due to their age, and partly due to better fitness.
-what could this be down to? am I just lazy and not pushing myself hard enough?
-am I not doing as much work in the group as I think I am?
-impossible to say for reason X (please state reason X)
i thank you
