Did anyone notice the max HR for today? That is what my HRM tells me. Seriously is that even possible? The general (not very accurate) method for calculating HR is 220-age, which makes my max 189. I've used another formula I found somewhere (not sure where) which calculates my max at 195, so this is where my HRM is set. I've reached 195 before, but I don't think I've gone over that.

I'm off to do some research on heart rates and HRM accuracy.
