During the TD Five Boro Bike Tour, approximately 32,000 cyclists pedal their way through all five boroughs on a traffic-free, 40-mile course. As its name suggests, the event is a tour, not a race—so participants can relax and enjoy one of the best ways to see the City. Alas, the tour is so popular (it's the largest bike event in North America) that a lottery was implemented to fill spots during registration this year. You can still enter, though, as a VIP or by committing to raise money for one of the Tour's charity partners. And, of course, you can always attend the event as a spectator.
