i started working more this summer, and deliberately found a place to live off-campus, so my commute is about 20 miles round-trip (depending on class and work... 5 to class, 5 more to work, then 10 back again). if i can find the motivation, i try to squeeze in 20 miles or so before or after work, and then 40-60 miles on the weekends... it averages out to about 150-200 a week, but that's just during the summer! during the regular semester i'm lucky to get in 20 miles a week, outside of the 30-mile races on the weekends.
