Although right now I'm doing about 15 miles (roughly about 26-27 KM depending on route) in the Spring that will be almost doubled with a new commute route because of the fact that my campus is moving father away (will become 22KM each way).
I know I've become addicted to cycling because I'm actually looking forward to it -- *MEH* .. maybe it's just because they have showers and an actual bike locker in the garage...
