Austin has some serious hills, and I did a few this past week. I could get on the bike today if I made myself. It's gorgeous here today, but you have to take a breather now and again. The majority of the mileage was commuting. It's a 40 mile round trip with a 10 to 20 pound messenger bag on my back.
UMD - that's crazy mileage. How do you find the time to do that?
