While you're at it, take a look at other places that you can commute to. The gym / pool is a great one. If I have a 60 minute recovery ride and a hard swim for the day, I'll ride to / from the pool (30min each way - fyi, you can break up recovery rides / runs and still get the same benefit). A good light, rear flasher and side-street route is key.
