I recently started walking to work, because by bike it is only 11 minutes and I felt I did not get enough exersize. Walking takes up about 33 minutes for the same distance. With my precious job, it took me abou 25 minutes biking to work. I think that the travel time is an important factor in the selected mode of transportation.
