I'm a bike commuter as well and I love it. Been doing it for about 9 years now. The first 2 years it was a 40 minute bike ride each way. After that I got another job and moved which resulted in a 15 minute ride each way.

Funny thing is I kind of miss the longer commute. Sometimes after work I will take an extra 30 minutes on my bike by taking the long way home. How many times do you hear a car commuter say that?

My current door-to-door commute is about 10 minutes. Most of that is spent waiting for elevators. I'm often late, strangely enough.

Previously I had a 30 minute each way commute by bike, with most of it along a river. I really miss that commute. Watching the seasons change, the different critters come and go, riding faster than the commuters stuck in traffic and feeling really 'connected' to the city. And 2-3 times a week i'd take a longer way home just to get a little more enjoyment out of the commute.

My commute has been ~30 minutes each way for the last five years. Seems like a perfect distance. Previously, I had a 20+ mile commute (each way), which I did three days a week. That was not ideal.

I rotate between commuting by motorcycle, bicycle, and train. Traffic usually works out to where each option takes about the same amount of time, 40 minutes.

Just having the option of not taking the train is a relief sometimes. If it's a beautiful day out, i'll take the bicycle in and get a wonderful start to the day. If it's a little rainy or I'm wrapped up in a book, I'll take the train and get some more reading time.

Also, having an iPad has made the train much more enjoyable.
