I seem to fall right in the middle with an 8 mile each way commute on fairly flat land. It takes me 30 to 45 minutes each way (the 45 is usually coming home after a 12 hour shift!) and I occasionally change the route to get in a few more miles if I have the time to do so. I'm a rain weenie, so I have a really hard time getting the bike out of the garage if it's raining, but I just added fenders on the Fisher and picked up some rain gear, so I'm trying hard to talk myself into it!
