The Marquette Trail 50 features both 50-kilometer and 50-mile races with a challenging course primarily made up of single-track trails. Runners will ascend four significant peaks: Sugarloaf, Top-of-the-World, Bareback, and Hogback, each offering stunning views of Lake Superior. Sections of the trail run along the lake’s shoreline, adding to the scenic experience. The terrain consists of moderate to difficult sections, characterized by steep climbs and technical areas. As rated by Ultrarunning Magazine, the course earns a 3 out of 5 for its hilly terrain and a 4 out of 5 for its rugged surface, which includes substantial rocks, roots, and ruts. To ensure a top-notch experience, participant numbers are limited, and the 50K event tends to fill up quickly.
