Bike MS NYC

With the economy still in the doldrums, nonprofits need more support than ever. Raise funds for the National MS Society, which is helping to find the cause and a cure for multiple sclerosis, on this annual ride. Three routes are offered, the shortest being a 30-mile jaunt around Manhattan. Opt for the 50- or 100-mile rides, and you'll haul ass under the Hudson River through the Holland Tunnel before taking a scenic, traffic-free path that winds through New Jersey and upstate New York; you'll ride back into the city by way of the George Washington Bridge. Reservations required.
