C&O Canal 100

The C&O Canal 100-mile race is your chance to chase big goals along the stunning Potomac River! Perfect for first-time 100-milers and veterans alike, this fast and friendly course offers one ~40-mile loop followed by two ~30-mile loops on the historic C&O Canal towpath, with nearly every mile close to the water and the Appalachian mountains.
