Wild Duluth Races

The Wild Duluth Races are a multi-day trail running event held October 17-18, 2026, in Duluth, Minnesota. The event includes ultramarathon and shorter trail race distances organized by Adventure Running Co. Courses use sections of the Superior Hiking Trail and run largely within Duluth city limits, passing rocky, rooty terrain and offering views of Lake Superior.

The event schedule groups the longer ultramarathons on the first day and the shorter races on the second day. The races have offered race apparel with long-sleeve shirts for the longer distances and the half marathon listed as unisex cuts, and short-sleeve shirts for the 10K in separate men's and women's cuts; participants are advised to note sizing differences. The races list multiple distance options and entry pricing tiers for different event categories.

Race facilities and exact course details are provided by the organizer. The event location references Bayfront Park and nearby sections of the Superior Hiking Trail in Duluth, MN. The Wild Duluth Races have an established history, noted as the 18th running of the event in event materials. Visit the organization's website for the most recent information.
