My time in the saddle each day is about 1 hr even. My 7 mile commute takes me 30 minutes +/- a couple minutes either way. Tack on an extra 5-15 extra minutes to shower and/or change at work in the AM and you're up to maybe an hour and a quarter per day. I shower when I get home, but that doesn't really count, because that shower is normally just in place of the pre-bedtime shower I used to take before I started bike commuting.

By metro, including walking and from stations, the commute to my office takes around an hour one way, so I'm saving at least 45 minutes a day plus getting exercise, stress relief, etc., etc. The bike commute for me is, therefore, an absolute no-brainer. And now that I'm hooked, I hope to keep doing it wherever I work until I retire, even if it twere to take a little longer.
