Wild Duluth Races

Wild Duluth Races is a weekend trail-running festival in Duluth, Minnesota, on the rugged Superior Hiking Trail with spectacular views of Lake Superior. The program includes 100K and 50K ultramarathons on Saturday, plus the Harder ’n Heck Half Marathon and Terribly Tough 10K on Sunday. Runners traverse rocky, rooty terrain that threads through Duluth’s city limits into wild trail sections, finishing at Bayfront Park for the longer races and at Spirit Mountain for the shorter events.

A Wildman/Wildwoman challenge adds extra motivation, with optional discounts for volunteers. The course is known for its ruggedness and scenic overlooks, drawing runners from across the region. Visit the organization's website for the most recent information.
