Grand Island Trail Runs

The event takes place on Grand Island in Lake Superior, Michigan. The course follows the island's perimeter trail counterclockwise. It passes Murray Bay, Duck Lake, and the Tombolo area. It goes into the island's thumb and then along Trout Bay shoreline. Runners ascend the eastern cliffs for views of the Pictured Rocks National Lakeshore.

The northern half of the island features 300-foot colored Jacobsville sandstone cliffs and North Beach. The return trail on the western shore offers vistas of Lake Superior. Much of the trail is shaded by hardwood forests. Exposed cliff-top sections experience breezes from the lake. The trail includes single track, two track, and narrow dirt roads.

The event offers three distances: 50K, Marathon, and Half Marathon. Registration for the event is open. Visit the organization's website for the most recent information.
