The Hare Mountain 100, set for October 23, 2026, offers an unparalleled ultrarunning challenge deep within Arkansas's Boston Mountain segment of the Ozark Highlands Trail. This "graduate level" event, renowned as one of the hardest 100-mile ultras in the United States, promises an exceptionally difficult yet stunning point-to-point journey for the 100-mile distance, starting at Haw Creek Falls Recreation Area and concluding at Shores Lake Recreation Area. Runners will traverse 100 miles of the OHT's most demanding sections, encountering rocky, steep, and rugged terrain, big climbs, and relentless smaller ascents, accumulating between 20,000 and 24,400 feet of elevation gain with a 38-hour cutoff. Expect breathtaking scenery, including numerous creek crossings, magnificent fall colors, waterfalls, bluffs, and striking sandstone outcrops as you push your limits to Hare Mountain, the OHT's highest point at nearly 2400 feet.

Beyond the epic 100-miler, the event, largely centered around Shores Lake Recreation Area, features a 50-mile race with 10,000-12,000 feet of gain, a 50K boasting over 7,000 feet of elevation, and a challenging 25K loop with around 3,500 feet of gain. Typical race day conditions in late October are ideal for endurance, with highs around 68°F and lows around 48°F, and a modest 14% chance of precipitation. However, this race demands self-sufficiency and navigational acumen; runners must carry a satellite GPS device with the course GPX file downloaded, as flagging is minimal, and distances between the 13 aid stations can range from 4 to 12 miles.

Known for its raw wilderness experience and a finisher's buckle often praised as one of the coolest, the Hare Mountain 100 is more than just a race; it's a testament to endurance and a contribution to a worthy cause, with proceeds benefiting local animal shelters and the Ozark Highlands Trail Association. Participants are even encouraged to complete trail work or make a donation to the OHTA. Prepare for an unforgettable adventure that truly tests your mental and physical fortitude amidst the stunning autumn beauty of the Ozarks.
