Grand Island Trail Marathon - Munising, Michigan - Running

The Grand Island Trail Marathon is a Running race in Munising, Michigan consisting of a 50K (Ultra) and Marathon and Half Marathon Trail Run.

Grand Island is an extraordinarily beautiful wilderness island in Lake Superior. 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 head up the eastern shore of the island which treats runners to views of the Pictured Rocks National Lakeshore. The northern half of the island features 300ft colored sandstone cliffs and the remote and exquisitely beautiful Northlight Beach. The return trail on the islands western shore features remarkable vistas of Lake Superior. Runners in the 50K will head inland at mile 22 on a trip past Echo Lake and up to the island's summit and then return to the marathon course at mile 27. 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 measured via GPS (+10ft). Each mile is marked.
