Race Info
High-altitude gravel marathon on Gravelly Range Road near Ennis, Montana, run entirely above 8,500 feet. The full marathon is an out-and-back that climbs to about 9,600 feet before finishing at Clover Meadows; the half marathon covers the same route point to point. Long promoted as the highest road marathon on the planet, though newer high-altitude races elsewhere have since challenged that claim. Capped at 150 runners under a US Forest Service special-use permit.
