Not up for the challenge of following the race all night? Couldn’t travel to northern Michigan the last weekend in July? Don’t worry, you can still follow the race and all the action. Each boat is equipped with a GPS system allowing real time tracking for the entire 120 miles. To view the GPS tracking map, click here. In addition, radio updates are provided throughout the night on the Marathon flagship station, 98.5FM WUPS, and Black Diamond Broadcasting network. You can view the station coverage map in the Program Book and Spectators Guide.
