Maybe this isn't enough of a saga to warrant the term "denouement" but I finally fixed my HRM. The strap battery was dead. I must say that I'm not very impressed with Polar for selling me a dead HRM strap. So after determining that it was something wrong with the HRM and not my heart by having some other guinea pigs try and fail to make it work I went down to Skinny Raven and bought a new strap. And now I know my heart rate, but frankly, I'm not all that convinced that it was worth the aggravation.
