I recently got myself a basic Polar HRM and so far have just used it to try and understand what I’m currently doing (when just going for a ride). Baselining I suppose.
Seeing those numbers quoted above has got me thinking I’m already doing something fundamentally wrong:
I’m 43 and tend to max at about 182bpm at some point on most rides.
Resting hr is circa 60 bpm.
A typical night ride at the moment would be 2.5 hrs at an average of 155bpm (reasonable pace but still stopping, chatting, waiting for stragglers). That would be 85%, which sounds too high!
Two weeks ago, that first really cold night, there were only a couple of us out so we ended up doing 3 hrs with no stops (other than gate opening) and averaged 165bmp. That would be 90%!!! I was cramping-up occasionally towards the end of the longer climbs but this eased if I backed-off a bit.
Pre-HRM, I’d have judged the intensity of a ride by “If I’m cramping up then I’m trying just a little too hard, and backing off a little next time out to avoid it.
I’m not super-human, so those percentages surprise me.
Your thoughts?
