My commute is 10 miles in the morning and 12-13 miles in the afternoon. The terrain is hilly with only a few flat stretches, but the pavement is good and parts of my route are shaded by trees. I start in the suburbs and ride on neighborhood streets for the first 4 miles, then 1.5 miles on a busy four-lane street. It is the only busy street on my route but unavoidable. Then another 1.5 miles on commercial streets that are wide with not much traffic, followed by 2 miles through a quiet neighborhood. The last mile I have to cross one of the largest, busiest traffic arteries in the city. My office building is right after that intersection, and I do a lap around the building, which adds another mile. The afternoon commute is the pretty much the same in reverse, except I add an extra 2-3 miles on neighborhood streets closer to my home.

In October, my office is moving downtown, which will add another 4-5 miles to my route each way. That will make it about a 30-mile round trip. I am going to try to keep commuting at my current frequency, which is 3-5 days/week, but will have to see how that works out. The big problems are the extra time that it will take because there are a lot more traffic lights as I get downtown, and I won't be able to store my bike in my office, which will entail more time locking up my bike and removing gear that might get stolen.
