At some point every spring, we hear about this 42 mile bike tour through New York City on car-free roads, and when we go to sign up, we're too late to register. Not this year! Registration is currently open for the May 3rd Five Boro Bike Tour, which starts in Battery Park, heading north through Central Park, Harlem, and the Bronx, returning south along the East River on the FDR Drive. From there the tour crosses into Queens and then Brooklyn, heading over the highway before rolling over the Verrazano-Narrows Bridge to Staten Island, culminating with a festival at Fort Wadsworth, free massages, and a lift back to Manhattan on the Staten Island Ferry. Organizers allow 30,000 cyclists to participate, but registration always fills up quickly, so if you like the idea of riding your bike down highways and over bridges without any cars breathing down your neck, do not sleep on this. This year's ride, which costs $48, also encourages cyclists to pedal for charity.
