Why did you use the word "normal" in your thread title? You know your commute length isn't normal. Normal bike commute lengths are usually one to six miles.

My commute is 14 miles each way. I don't have a car. My other mode is the subway. Each mode takes about the same amount of time, so when I decide which to use, time isn't really a criterion, though preparing for the bike commute takes a little longer.
