I am 47 - My heart rate hit 190 somewhere around Holme moss circuit yesterday. I have seen it go to around 173-177 before. As I have had a break recently it seems to have hit 180 ish in the heat.
Whats a dangerously high heart rate? Apart from proving it was by falling over and dying to prove it
I have just a basic garmin watch thingy so just use it to look at basic stuff. Noticed a few times some higher max heart rates than before. Not something I think about generally just noticed the stat.
