Cool tool for walking too
I found this site to help track how far you run. I'm only walking..but same difference. It's cool because you can plan out or go back and see how far you actually walked without having to take the car out and clock it. If you set up a free account, it will also keep track of all your walks/runs and let you do all kinds of neat analysis. (Not sure that I'll use all that, but it is cool to be able to track your routes.) Hope you find it helpful!!
