Running

I don't understand the Phoebe reference.

I've seen 185 come up when riding up Ide hill, however when I went above ~182 today it felt like I had a belt clamped round my chest.

I had to back off a bit at that point.

hmm, I'm partially asking because I'm not sure about mine and mine is set purely based on a good old fashioned 220-age, as I havent done any proper analysis, but actually looking at some activities in the last few weeks which I would have expected to get to max HR suggest the number is lower than that.

For me getting close to max HR feels more like passing out, tunneled vision than tightness in the chest, but its probably a bit of a personal thing...

If you've seen it a few times, you must be either working out at an incredibly high intensity, or you're not hitting your max HR, in which case there's more to give which would then change your "zones".

Basically I think I'm going to have a crack at doing a proper max HR test in the next few weeks
