Lace up for one of the most breathtaking trail races in the Midwest! The Grand Island Trail Marathon is more than just a run; it’s a wilderness adventure on Lake Superior’s largest island. With three unforgettable race options, the 50K, Marathon, and Half Marathon, you’ll tackle sandy beaches, shaded forest trails, and jaw-dropping cliffs high above crystal-clear water.
It’s all happening on July 26, 2025! After a quick ferry ride from Munising, runners start hitting the trail at 6 a.m. from Williams Landing and dive straight into the wild beauty of Grand Island. The course winds through towering pines and along sandstone bluffs, all with Lake Superior never far from view. It’s a rugged, remote adventure from start to finish… and yes, a post-race plunge in the lake is practically a rite of passage. Keep on reading for all the information you need to prepare for the Grand Island Trail Marathon!
