9.7 to 30.5 miles each way depending on how I go.

Biking all the way is 21.8 miles which I do most of the time. If the weather is bad, or I'm pressed for time, I can take a train which cuts the bike portion down to just 9.7 miles and saves 30 minutes. However, when the weather is nice, I sometimes take the 30.5 mile "scenic route" which lets me bypass a nasty section of road in the middle of my normal commute.
