About the race
Grand Island Trail Runs take place on Grand Island off Munising, Michigan on July 31, 2027. The event offers trail courses around the island that follow shoreline and interior trails, with views of Lake Superior and nearby Pictured Rocks.
Distances
- 50K
- Marathon
- Half Marathon
Courses use a mix of singletrack, two-track, narrow dirt roads and sandy beach. Notable course features include Trout Bay, Echo Lake, Murray Bay, Duck Lake, the island tombolo, and colored Jacobsville sandstone cliffs along North Beach. Much of the route is shaded by hardwood forest and is marked with colored flags, directional arrows, and mile markers. The 50K route follows the island perimeter counterclockwise and includes an inland section to Echo Lake and the island summit. The half marathon is a loop that includes beach running on Trout Bay and finishes at Williams Landing.
Aid stations are positioned along the courses; the 50K lists five stations with two of them visited twice for seven stops total, while the half marathon has two aid stations on course. Aid offerings include water, an electrolyte drink (Gnarly Fuel2O), and light sweet and salty snacks, plus fruit. All runners are required to carry a 20 oz water bottle or similar hydration system.
Logistics note that ferry transport to the island is included with registration and takes about 10 minutes. Parking at the ferry dock is limited; shuttle pickup locations are provided. Entrant limit is 500 and registration closes July 26, 2027. Visit the organization's website for the most recent information.
