Extreme North Dakota Sandhills Ultra Run Experience (END-SURE)

A beautiful trail run with 25K, 50K, 100K, and 100-mile 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 second-longest footrace and first ultramarathon. The date makes the shorter 50K and 25K options great early season training or final long run leading up to Zumbro.
