Come watch a spectacular race of all-terrain, human-powered vehicles with an art twist. Created by the competitors, these engineering feats will race down Middle Street to the Maddening Mud Pit near the Tsongas Centar, brave the waters of the Merrimack River at Heritage State Park, then drive to the finish line on Market Street. Dress up to support your favorite team, and follow behind the race on your bike or on foot! Music, food, and family activities on Market Street and Heritage State Park throughout the day. A Spectator Guide is available.
