Since 1994, environmental advocacy group Time’s Up! has organized monthly eventide bike rides through Central Park and Prospect Park. The loops around and through the parks are less than ten miles and can be completed in less than two hours, making them suitable undertakings for someone looking to improve their fitness and endurance in a fun, social environment. There are a few stops along the way to rest your gams while taking in scenery, including the glowing city skyline and the parks’ moonlit ponds. The group also offers a large number of other rides, check the website for the full schedule. Manhattan: meet at Central Park Merchants’ Gate, 59th St at Broadway; first Friday of the month at 10pm. Brooklyn: meet at Prospect Park Grand Army Plaza entrance, Eastern Parkway and Prospect Park West; second Saturday of the month at 9pm. times-up.org; free
