When I first started thinking about HRM's, I didn't see the point of being able to log the information. I figured seeing my heart rate while riding was enough. While the S725 may be overkill for me, I got it and I'm glad I did. I rarely look at it while riding. If I'm riding hard enough that I want to know my heart rate, I'm usually pushing too hard to be able to take my eyes off the road. It's cool to be able to download that info when I get home and see where I was pushing myself and where I let up. If nothing else, I'll be able to easily compare this data to see any improvements down the road. Knowing my altitude and cadence at those respective points is pretty neat too.
