Maah Daah Hey Trailrun
The Maah Daah Hey Trailrun is a multi-distance trail event on the Maah Daah Hey Trail through the North Dakota Badlands. The event is scheduled for July 30th-31st, 2027 and finishes at the Theodore Roosevelt Presidential Library in Medora.
Distances offered include:
- 3.1+ miles
- 6.2+ miles
- 13.1 miles
- 26.2+ miles
- 56 miles
- 112 miles
The course is largely continuous single-track with frequent climbs and descents. Surface types include dirt, clay, sandstone and scoria, with prairie tops and sparse tree cover. Multiple creek crossings occur on every distance; some crossings may be dry while others require getting wet. The new 116-mile out-and-back course eliminates a Little Missouri River crossing for 100-mile entrants.
Support infrastructure includes aid stations or "oases" roughly every 25 miles with volunteers, shaded tents, chairs, porta potties and water. There are about nine major checkpoints where the trail meets main back roads; porta potties and water appear at checkpoints and volunteers assist at some locations. The 100-mile cutoff is set at 36 hours.
Shuttles transport runners for the 10k, half marathon and marathon to their start lines; 50, 75 and 100 mile participants must provide their own transportation to starts and have a plan for removal if unable to finish. Pacers are permitted for the ultras subject to age, registration, bib and checkpoint rules. Awards include finisher medals for shorter distances and belt buckles for ultra finishers, with top three overall and age-group prizes.
