<p>I don't use the numbers, so I don't bother spending money on it. I have a full bore GPS/HR for the bike. It's a nice Garmin. Plots routes and HR's, all down-loadable, but I found that I never look at the numbers. I know where I need to be in order to last a long time, and I know where I need to be when going all-out, even for intervals and racing and such. And so I stick with it. I really enjoy getting to know my body and how it performs so well that I can, like a fighter pilot at controls, fly this sucker under a bridge and around a tall building at mach speed. Or so I feel.</p>
