I wore it cycling today and it was very interesting. There were a lot of times when I was pushing when I didn't realize it (had a nasty headwind) and the "bad" hill that I thought would get me up past 180, didn't. My high was 175

Then again, I'm still building up to it so granny gears are in order. My average heart rate on a 44 mile ride with wind and some hills was 145.

Redcanny, is it a Polar F11?

Thank you to Wahine and everyone else. It's all new and complicated but I'm learning little by little
