BITD, we used fixies for winter training: started out with a 42/21 on Jan 1, moved up a tooth every two weeks (42/21,20,19,18) then switched back to gears. Great workout, no worries about over-gearing and it gives you a GREAT spin (try a 30mph downhill on a 42/21 fixed some time. It's an eye-opener.) That said, I haven't ridden fixed in probably 35 years. Musta got it out of my system.
