Hare Mountain 100 2026

Hare Mountain 100 is an October trail-ultra series in northwest Arkansas, centered on a 100-mile point-to-point run from Haw Creek Falls Recreation Area across the Boston Mountain segment of the Ozark Highlands Trail. The main race has its organizers as a graduate-level event: approximately 21,000 feet of climbing, a 38-hour cutoff, and 100 miles selected from the most challenging sections of the trail. Shorter options include 50 mile, 50k, and 25k races starting at Shores Lake Recreation Area, though these are not easy options; the 50 mile has over 12,000 feet of gain, the 50k over 7,000, and the 25k over 3,500. The route crosses remote Ozark Highlands Trail terrain featuring rocky forest, steep ascents, creek crossings, waterfalls, bluffs, and sandstone outcrops. Hare Mountain itself is the highest point on the trail at nearly 2,400 feet. Runners must be comfortable navigating without extensive course markings beyond white and blue blazes, wooden signs, and their own GPS devices; the 100-mile race mandates a satellite GPS tracker and the GPX file on a phone. Aid stations are spaced out, with some major ones up to 12 miles apart, and the event uses MAProgress tracking. Pacers are permitted from approximately mile 17, but the event still requires self-sufficient runners capable of handling solitude, potential navigation errors, fallen trees, fog, leaf-covered paths, and extended periods in the Arkansas backcountry.
