Thanks for the input – I got the Joe Friel book for xmas but if I’m honest its a bit in depth for someone who is looking at using a HRM for training for the first time.
I have seen 202 max on gym machines when doing flat out 5k rows a few years ago, but always assumed this was wrong and that the gym machines were inaccurate. I was surprised to still see such high figures when I got a proper HRM. (based on the 220 – age calc)
For now I’ve set the garmin to bleep at me when I go over 180 (around 90%) as it seems to be the magic number and I know I cannot sustain that HR for more than 3-4 mins before blowing up, but even on my usual ride I am regularly and consistent going over it and I feel like I’m riding really slow.
So far I’ve been on 3 rides since getting the garmin and returning to the bike, and my HR has been averaging 165 for a 2.5hr off road ride (7.8mph av) to 170 for a 1.5hr (8.8mph av)
These figures seem ridiculously high (over 80% max) based on how I feel during / at the end of the rides. Ie. Not half dead.
Factor in I have sat on my arse for 3 months nursing a broken collar bone and gaining a stone in weight it just doesn’t seem right.
I borrowed a friends polar HRM today to check on a run and it was recording similar figures to the Garmin, so its not a dodgy monitor
I’m finding it all a bit confusing, the hypercondriac in me is murmuring I may have a heart problem…..I’ll dig more into some of the other links posted!
