Elkhorn Endurance Run 50 Mile Course Profile

Elkhorn Mountains, MT (near Helena), Montana

A brutal, remote 50-miler in Montana's Elkhorn Mountains, put on by HURL from the Willard Creek Trailhead. 37 miles of very technical singletrack, 13 miles of jeep road, and roughly 12,000+ feet of climbing with a high point just under 9,000 ft. Six big climbs, a pass through the Elkhorn ghost town, and tight cutoffs make it one of the toughest 50s in the northern Rockies.
