There are already similar events going on in May and June in Arlington, where certain streets will be closed to cars:
Bike DC on May 13
Crystal Ride (Air Force Cycling Classic weekend) on June 10
True, both rides require a registration fee for cyclists, but both are untimed noncompetitive rides on the roads of Arlington (and D.C., for Bike DC). (Competitive cyclists do have some incentive to ride hard during the Crystal Ride. It’s untimed, but they track how many laps you do during the 3 and 1/2 hr. time period. Beginners can just take in the scenery and atmosphere and go as slowly as they want, and stop riding when they want to. The hyper-ambitious folks can race around the course and try to complete 6 laps, which will take some doing. That’s almost 56 miles. Not too bad for an advanced rider but definitely more than an easy stroll on the bike.)

For an ongoing “open streets” day or ciclovĂa, you would have to take into account the weather as well as the existence of other events. I don’t think there would be any point to having the bike day during the winter, even when there isn’t that much snow on the ground. The cold weather will keep most people away so the expenses wouldn’t be worth it. I’m also wondering about the midsummer too. The hardcore cyclists might be out there in mid-July, but would most of the casual cyclists? I don’t know. August is kind of dead around here, with Congress out of session and many people heading out of town on vacation.
Spring and fall would be ideal for these events. With Bike DC and the Crystal Ride, I don’t know if we would need another spring event, except maybe in April. The fall could present some scheduling problems because there are a lot of running races going on then, almost every weekend. This includes all of the shorter races like 5Ks (including the popular Clarendon Day 5K) to the big races like the Nation’s Triathlon, the Army Ten-Miler and the Marine Corps Marathon. There are many running races in the spring too, with the Cherry Blossom Ten Mile Run being the most well-known.
