Wild Duluth Races
Downtown - Waterfront, United States • 18-19 Oct 2025
Wild Duluth Races, held in Duluth, Minnesota, offer rugged 100K and 50K ultramarathons on the Superior Hiking Trail, first established in 2009. The weekend also features the Harder ’n Heck Half Marathon and Terribly Tough 10K trail races, with dramatic views of Duluth and Lake Superior from rocky, rooty trail sections. Runners traverse the city limits while feeling like they’re in the wild, finishing at Spirit Mountain. A key feature is the Wild Man/Wild Woman challenge: complete the 50K and 100K on Saturday and the half on Sunday for the title. Volunteer participation can earn race discounts.
