Track your rides and runs via your iPhone, Android or GPS device, analyze your performance, and compare with friends.
I'm thinking of getting a heart-rate sensor so that I can get some data when I start riding the rollers.
Flats are a pain, but as long as you are prepared, it's all part of the experience. Also thinking about replacing my "bic-lighter" pump with full-size frame pump - I miss my Zefal HPX.
Ha, I agree but I am in a rash of flats that are being caused by something else. I just haven't figured it out yet! I use air canisters, much simpler!
