Hare Mountain 100

Hare Mountain 100 is a multi distance trail event in Hagarville, Arkansas, based at Haw Creek Falls and Shores Lake recreation areas. Distances offered include:

  • 100 Miler
  • 50 Miler
  • 50K
  • 25K
  • 15 mile Dirty Doo

The 100 mile is a point to point, graduate level run on singletrack along the National Scenic Ozark Highlands Trail through isolated, rugged terrain. The event uses MAProgress satellite GPS tracking and Ultrasignup aid station in/out times supported by Starlink at aid stations.

The 25k is a loop from Shores Lake with about 3,500 feet of elevation gain and a 4pm cutoff. The 50k is an out and back from Shores Lake with 7,200+ feet of gain and a 10 hour cutoff. The 50 mile is an out and back from Shores Lake with about 12,000 feet of gain and a 16 hour cutoff. The 15 mile Dirty Doo is a run then bike duathlon on a 15 mile loop; participants run the loop first and then bike it for a total of 30 miles and about 4,200 feet of gain. The Dirty Doo course is roughly 70% gravel and 30% chip seal or paved, with one aid station at Salt Fork.

If added, the Black Bear 105k will be an out and back from Shores Lake to Morgan Fields trailhead with over 15,000 feet of gain and a 20 hour cutoff.

The 100 entry fee is $315 plus fees, rising to $330 after August 31. Tracking device rental and shuttle options are available for additional fees. Included items and services for 100 mile entrants listed by the organizer include tracking software, stocked aid stations, a long sleeve tech shirt, finish buckles and medals, wooden awards, and sponsor swag. Discounted slots for financial assistance are available.

Past 100 mile finish rates under 38 hours were reported as 0% in 2023, 43% in 2024, and 36% in 2025. Camping is available at the finish campground.
