About
Grand Island Trail Run takes place on July 24, 2027, in Munising, Michigan. Three trail distances are announced: 50 km (31.1 mi), a marathon (42 km) and a half marathon (21 km), on a course crossing lakes and dense forest. Start times and elevation gain are not listed in our records.
Island courses have a particular constraint worth checking before you enter: access is by boat, which fixes your arrival, your departure and your drop-bag logistics far more rigidly than a road race does. On the running itself, Upper Peninsula trails in late July are soft and often damp underfoot — choose shoes with real grip rather than your fastest pair.
Highlights
