Now that the weather is better I have restarted my bike commuting. Although my ride is short and safe - mostly on a MUP which I gt on 2 blocks from my house and off right at the main gate outside my office, I found that if I tried to make it a high speed endurance ride I would not bike commute. The time I spend on the bike to work is spent mentally preparing for the day, and that could be listening to the birds or enjoying the sun before I box myself up. During the ride home I usually feel like a little kid, happy to be out of the box and enjoying the outdoors.

So if your commute is going to be stressful - bike commuting will probably not be a long term thing, if you can find a way to make it fun and safe then it will be.
