This evening I finished my FIRST week of commuting on a bike. 70.2 miles in four days riding (was rainy on Wednesday and I do still own an S10 pickup), had one close call the first day, two flat tires (one the first morning, another this afternoon before the commute), and lost 9 lbs the last two weeks. I would call that a GOOD week. I've worked out most of the bugs in the commute, am comfortable with the routes, and really enjoy being able to get on my bike twice a day. The average speed will come up a bit (about 16.2 now) as I get in better shape and people on the route get used to seeing me and make those small allowances. Three miles of the commute is in the bike lane of a BUSY highway, and those miles I don't much enjoy with 18 wheelers passing three feet away at 55+, but I can live with it. All-in-all a VERY POSITIVE EXPERIENCE...
