I live in Mountain View and commute every day to San Francisco. This is more than 50 miles in each direction, and the freeways are terrible. But since I have been doing it, for the past four months, my wife has bought me a whole set of new pants. Smaller pants. I ride my bicycle about 2.5 miles on each end of Caltrain. 10 bicycle miles per day, with high consistency, has markedly improved my health. 10 bicycle miles is not much. But I push hard, each of those four separated segments, to be well winded. I have always hated exercise, and never did it consistently. But I intentionally set myself up to be "forced" to exercise. It is a 55 minute train ride on the front and 45 minutes on the back. And I get most of my best work done on the train. Because I catch 5:57am and the 3:37pm trains, I always get a good seat. My wifi is generally good. So it makes for a relatively long day, but I physically feel better than I have in a long time, and working on the train and early in the office gives me a lot of high quality "heads down" time every day, which is so important. As stated elsewhere, the commute itself is less important than the quality of the commute.
