8mi each way. Sometimes I go on longer, prettier routes (Rainier, the Sound, Lake Washington, Arboretum, etc), bringing it up a few miles and minutes.

I'd have less energy if I didn't commute on the bike. But 30mi each way is a bit much [edit: for me, that is].

Austin's got some pretty good hills, if you're on the Western side. I've never gone faster than I did on 2222 - freewheel enabled of course.

Our buses here have bike racks, which means you can ride and ride if you need. I know there are some buses in Austin, but I never really paid them attention. What's your commute like (routes?)?
