Give it a shot. What have you got to lose? My commute was 22 miles round trip when I first started, and at the time my plan was to ride once a week -- on "dress down" Fridays. Pretty soon I was riding 2 days, then 3 days, and then nearly every day. My commute distance increased to 30 miles round trip in October, and I wasn't sure at first whether I could continue riding as often, but so far I have been averaging 4 days a week. The distance is no big deal once you get in shape, but it takes a while to work out all of the details.
