With Car Free Day coming up tomorrow, it’s as good a time as ever to remind everyone of another two-wheeled celebration — Bike DC. The October 17 event will feature two routes — the 25-mile Capital Ride and the 12-mile Family Ride — that weave their way through parts of the District and Arlington, including a stretch on the George Washington Parkway.

There is one catch that might make the rides a little longer for everyone, though — the start and finish lines aren’t in the same place. According to a FAQ posted by organizers, the event was only permitted to shut down one bridge, so all riders will start in Washington and end up in Crystal City. At that point, I’d encourage either taking the Mt. Vernon Trail back into the city or just taking advantage of strength in numbers and turning the event into an impromptu Critical Mass ride. It’s never too early to start teaching kids about subverting car culture, is it? Registration costs $35 for adults ($45 for same-day) for the Capital Ride and $25 for adults ($35 for same-day) for the Family Ride. Kids under 15 ride free. You can register here.
