The HM100 is October 23rd, 2026-10:00 AM at Haw Creek Falls Recreation Area.
The Hare Mountain 100 is a point-to-point, graduate level run through the most isolated, rugged terrain in Arkansas. It is extremely difficult. Big climbs and relentless smaller, steep climbs in between.
The Ozark Highlands Trail is hiked by thousands of people every year. While very remote, it is not a primitive, unmarked trail by any means. It is a National Scenic Trail maintained by volunteer members of the Ozark Highlands Trail Association.
But, please do not sign up if you are not comfortable with:
-being self sufficient
-no extra marking beyond trail blazes and wooden trail signs
-navigation
-carrying a little extra gear for your safety.
-long distances between some major aid stations (~12 miles is max on a couple, rest are below that distance)
A satellite GPS tracking device and the course GPX downloaded on your phone is a requirement for the 100. The tracker can be yours/borrowed or rented from Maprogress. It will be checked during check-in to make sure you have it. While the trail is marked very well with white blazes for the main trail and blue blazes for the spurs, turns can be missed. Sometimes trees fall where the trail turns. Sometimes the tree with the blaze falls. Sometimes leaves cover the trail. Sometimes it's foggy. It's the wilderness. It's a raw and incredible experience. Be confident you can stay/get back on course.
This is a 100 mile, advanced level, endurance event that incorporates 2 scenic spur loops along the Ozark Highlands Trail. It is located in the Northwestern part of Arkansas across the Boston Mountain segment.
Hare Mountain is the highest point on the OHT at ~2400 feet. This segment covers 164 miles of rocky, steep and rugged hardwood, cedar and pine forests. We’re utilizing 100 miles of the most difficult sections.
There are several creek crossings, amazing wildlife, incredible fall colors, waterfalls, bluffs and beautiful sandstone outcrops.
The race director grew up on this trail. It means a lot to her to bring such a wild and challenging experience to runners.
Measurements taken by GPS and topographic mapping have put elevation gain between 20,000-24,400 feet. It depends on the device/app. Runners will have 38 hours to complete the 100 mile run. However, if you make it out of the last aid station at Salt Fork by the cutoff but arrive at the finish after 38 hours, we still give you a buckle/official finish.
The 50 mile (6wm start on the 24th) and 50k (9am start on the 24th) are out and back courses for 2026 due to the shuttle focus shifting to the 100. That means more elevation gain for each. The both start and finish at Shores Lake recreation area. The 50 mile will turn around at Cherry Bend TH and has ~12,000 feet of elevation gain. The 50k turn around is Ragtown Rd. TH and has over 7,000 feet of elevation gain.
The 25k starts (9am on the 24th) and finishes at Shores Lake and it is a loop. Runners will go up the West side of the Shores Lake/White Rock loop, top out at White Rock lower TH parking, before descending to the spur for the East side of the loop. This course has ~3500 feet of elevation gain.
The White Rock Ascent starts at the junction of the East side spur and the main OHT. Runners run to the top of White Rock (lower TH parking) for their time and run or walk back down to Salt Fork Aid. It has ~1300 feet of gain in 1.8 miles.
Runners can camp at Shores Lake CG (first come, first served), camp in the national forest, rent a cabin in the area (White Rock) or find a hotel in Alma.
All of our distances are UTMB Index races because we realize some runners would like to run at UTMB. We are allowing runners to improve their performance score. without losing our autonomy.

We are planning to add a 200 mile run the same week(end) as the 100. Details will be available as course comes together with the forest service.
