Is there a good primer for HRM usage? My wife gave for a Polar F6 for my birthday, and I like using it so far. I wanted it so I could train a bit this winter and hopefully bike better come summer--I felt like I was dying on every hill this summer (novice biker), even when I was going slow, but had no gauge as to how hard I was working. And really couldn't get past the 3 hour barrier.
So far, I've taken it on one good off-road ride. Although 220-31 is 189, I did hit 195 towards the end on one hill. [I understand that max HR isn't set in granite.] For the most part, on any amount of climbing, it was 170-180, easy; a few times, 190. On descents I could get down to 130-something (which wasn't often). After an hour ten of that, I was beat! [Max of 195, average of 163.] I also did a short bit on the trainer, and 130-140 didn't feel that hard, a bit easier than what I was riding at over the summer (at least on the flats--in hindsight, I was probably pushing 180 on every hill).
