Portland-South Portland, ME

Running around Portland follows the coast and parks—the Eastern Promenade hugs the Atlantic with minimal elevation, while inland routes use the Fore River Greenway and trails up to 150m elevation. Cyclists have serious terrain options within 30 minutes: the Yarmouth Clam Festival Bike Race and Mainely Gravel tap into Maine's rolling inland roads and gravel networks, while the Trek Across Maine Gravel Ride showcases longer mixed-surface routes through the state's backcountry. The region's maritime character makes for distinctive multisport racing, including the OTILLO Swimrun in Casco Bay's islands.
