50K.U.M

The 50K.U.M is an ultramarathon event held in Houghton, Michigan, on the Michigan Technological University Tech Trails. It offers two race distances: a 25K single loop and a 50K double loop course through scenic wooded trails. The 50K race starts in the dark, requiring participants to use headlamps for the first 1.5 hours.

The course features multiple aid stations stocked with water, drink mixes, and typical ultra foods, and runners must check in at each station. The race has strict time limits—8 hours for the 50K and 7 hours for the 25K—due to the remote nature of the course. Parking and gear drop areas are conveniently located at the main trailhead.
