I have a mixed mode commute: home-bike-train-bike-work. I leave home at 0500 and arrive at work at 0715. So 4.5 hours is taken out of each day for commuting. I do this 2 or 3 times a week. But as others have said, I don't regard it as time spent transporting myself to/from work. I see it as a great opportunity to spend more time with my bike
