The awesome The Five Boro Bike Tour is going on today. Riders started in Manhattan this morning, they'll briefly head into the Bronx (and then back into Manhattan), ride through Queens and Brooklyn, and end in Staten Island, for a ride back to Manhattan on the Staten Island Ferry. Cheer the riders on when you see them!
Here's the map of the route. And if you're inspired to go for a bike ride today, here's the city's Cycling Map.
