Wild Duluth Races

The Wild Duluth Races include rugged 50K and 100K ultramarathons celebrating their 13th year running. In addition to the 50K and 100K ultramarathons on Saturday, we also run the Harder 'n Heck Half Marathon and Terribly Tough 10K trail races on Sunday. The Wild Duluth Races all enjoy spectacular views of the Northern Minnesota city of Duluth and mighty Lake Superior from the rugged, rocky and rooty Superior Hiking Trail. Runners from out of town marvel at the wild trails we possess here in Duluth. While you'll be running through the City Limits of Duluth most of the way, you'll feel like you're running in a truly wild place - Wild Duluth!
