July 24,2021 Grand Island Trail Marathon & Half Marathon in Munising, MI USA will be held this year.The course follows the perimeter trail of the island counterclockwise up past Murray Bay and Duck Lake. At three miles the course heads eastward into the Tombolo, up into the island’s thumb and then back along Trout Bay where runners can enjoy one of the most spectacular stretches of shoreline anywhere in the Great Lakes. Runners then ascend up the eastern cliffs of the island which treat runners to views of the Pictured Rocks National Lakeshore. The northern half of the island features 300 ft colored Jacobsville sandstone cliffs and the remote and exquisitely beautiful North Beach. The return trail on the island�s western shore features remarkable vistas of Lake Superior. Much of the trail is shaded by lush hardwood forests. Exposed sections (atop cliffs) blanket runners with cool breezes off of Lake Superior. Trail includes single track, two track, and narrow dirt roads. The course is well marked with colored flags, directional arrows, and mile markers. The marathon will have a two wave start. All runners who expect to finish in over 5 hours will start in wave 1 (6:00 a.m.). All runners in wave 1 will receive finisher medallions but will not be eligible for age group awards. All runners who expect to finish in less than 5 hours will start in wave 2 (7:00 a.m.). You can indicate your wave during online registration. Note: This is a trail marathon on a wilderness island. Do not expect large numbers of spectators and the comforts of a road marathon.
