I generally consider myself a working professional rather than a student, but I'm taking a night class this semester at our local community college, so I get to be a student again.
I was playing with the relatively new adjustable route feature on google maps, and this is (pretty much) the route I'll be taking to school:
Bike route to school.
I've carefully constructed that route to go around all the hilly parts of the city. I go a mile out of my way to the west just because it's nice and flat. Taking this class adds 16 miles per week on Thursdays to my commute, and some amount I haven't determined yet on Mondays and Wednesdays, since I'll be coming from work. Probably about an extra 7 or 8 miles per day. An extra 30 miles a week on the bike never hurt anyone.
