My comute consists of a 2.5 mile drive to the parking lot where I park. The roads and sidewalks between my house and the parking lot are just too hosed up to try to ride on. I see a couple of commuters riding it but not me. Once on the bike it's .5 miles to the traffic light by sidewalk, cross the street and 13 miles by bike path to downtown. From the path it's about .5 miles by back city streets to work. Theres one hill at the beginning thats about a 8%er for about 150 yards and one at the end thats about a 10%er for 75 yards. I hate that hill. Other than that it's mostly flat with some mild rollers tossed in. Takes me about 45 to 50 minutes into to work and about 50 to 55 to get home. Going to work is more down hill than up and going home is just the opposite. I do this 2 to 3 times a week depending on the weather. I don't mind the heat or cold but I hate riding in the rain.
