25K start in 2015, photo by Wes Peck.

A beautiful trail run with 50K & 100K, and options. 100K race takes in the entire length of the Sheyenne National Grasslands section of the North Country Trail, SW of Fargo North Dakota.  Sections of wide open prairie, pockets of forest, and rugged, rolling 'sandhills' keep the race interesting.  This event is North Dakota's first ultramarathon.
