Shawnee Hills Trail Races, Camp Ondessonk (Ozark, IL)
Shawnee Hills Trail Races are held at Camp Ondessonk within the Shawnee National Forest and follow a figure eight loop that traverses sandstone canyon systems, oak-hickory, maple-beech, and pine forests. The route includes notable waterfalls and rock features such as Pakentuck Falls, Jackson Falls, Horseshoe Falls, Cedar Falls, and viewpoints from Salomon's Ridge.
The course surface is roughly 80% single track, all dirt with some fire roads. Terrain is hilly and technical with rocks, roots, ruts, and creek crossings. Cumulative climb is cited in the range of 2,500 to 7,500 feet for a 50-mile equivalent. Runners may be exposed to heat and humidity and could encounter snakes, ground hornets, and bees native to the area.
