Hare Mountain 100

The Hare Mountain 100 is a challenging point-to-point ultramarathon held in the rugged Boston Mountains of Northwestern Arkansas, featuring distances of 100 miles, 50 miles, and 60K. The course follows the Ozark Highlands Trail, known for its steep climbs, rocky terrain, and scenic beauty including creeks, waterfalls, bluffs, and fall colors. Runners face significant elevation gains—up to 24,400 feet for the 100-mile race—and must be self-sufficient with navigation skills, as the trail is marked but remote.

The event offers well-stocked aid stations, GPS tracking, and awards including handcrafted buckles and wooden trophies. Proceeds support local animal shelters and trail maintenance. Visit the organization's website for the most recent information.
