I was kind of wondering the same thing so thanks for answering yourself!!! I'm up around 160 also and I feel ok there. It's frustrating because honestly, I don't know if I can GET any slower sometimes and to shut the darned thing up, I'll walk for a bit. I actually turned the beep off but still.

I'm torn about the whole thing. I wanted a HRM so I got it but I'm not so sure I like abiding by its regime.

You are good with it now? I haven't cycled with it yet, I'm about to go try. Yesterday I ran about 3 miles though and finally decided that I'd try to keep it around 150 but it was frustrating to go below that.
