The Shawnee Hills Trail Races, held on August 22, 2026, in Ozark, IL, offer an unforgettable and challenging trail running experience deep within the scenic Shawnee National Forest. Runners can choose their adventure from demanding distances including a 100M, 100K, 50K, and a Half Marathon. The course, predominantly an 80% single-track figure-eight loop, weaves through hilly, technical terrain, characterized by a relentless mix of rocks, roots, and numerous creek crossings designed to keep runners thoroughly engaged. This course navigates stunning sandstone canyon systems, traversing areas like Jackson Hollow and the Bay Creek Reservoir, and showcases multiple waterfalls, including the impressive Pakentuck Falls, Jackson Falls, Horseshoe Falls, and Cedar Falls, alongside inspiring vistas from Salomon's Ridge. With approximately 3,200 feet of elevation gain per 50K loop, this race is known for its difficulty, earning a reputation among runners as "crazy hard" and not for the unprepared.

Typical race day conditions in late August feature warm highs around 86F and lows around 63F, with a 12% chance of precipitation, meaning runners should be prepared for potential heat and humidity. Throughout the challenging journey, participants will find excellent support from five fully-stocked, manned aid stations spaced every 5 to 8 miles. These stations offer water, electrolyte drinks like Tailwind, snacks that evolve from traditional fare to more substantial options, and first aid, all delivered by enthusiastic volunteers. The race prides itself on being Trail Sisters approved, providing feminine hygiene products at all aid stations.

Starting and finishing at the rustic Camp Ondessonk grounds, the event offers a unique weekend experience with options for overnight stays in open-air "treehouse" cabins or traditional tent camping. This race is more than just a test of endurance; it's a celebration of nature, resilience, and community, allowing runners and their families to immerse themselves in the undisturbed wilderness of Southern Illinois. Be aware that encounters with native wildlife, including snakes, ground hornets, and bees, are possible, adding to the wild authenticity of the course.
