Good commute, though mine is short. Averaged 15.1 on my way to work and 15.8 on my way home. I work in a warehouse and stand 9 hours a day, so the verve of my ride home was a little unexpected!
Soon I think I'll invest in either a brooks B-17, or a few pairs of those under-athletic-shorts style cycling shorts. I didn't feel like wearing my regular Canari spandex for commuting!
