About this run
The Hare Mountain 100 is a challenging ultramarathon event set in the rugged terrain of Hagarville, Arkansas. This race emphasizes personal discovery, quiet reflection, and solitude amidst isolated and demanding landscapes. It is described as one of the hardest 100-mile ultras in the US, offering a true test of mental and physical endurance. The event features multiple distances, including a 100-mile race, a 50-mile, a 50K, a 25K, and a 10K. The 100-miler is a point-to-point journey on singletrack, traversing the Ozark Highland's Trail and reaching a high point of approximately 2400 feet on Hare Mountain. Aid stations are well-stocked and managed by experienced volunteers, with live GPS tracking available for runners. For those seeking a different challenge, the 25K offers a demanding loop with significant elevation gain in its initial miles, featuring technical descents. The 50K and 50-mile races are currently out-and-back courses designed to complement the 100-mile shuttle system, though point-to-point formats may return in the future. The event aims to provide a wilderness-focused experience with opportunities for camaraderie, camping, and shared stories.
