Ondessonk Trail Races
The Ondessonk Trail Races take place at Camp Ondessonk in Ozark, Illinois. This annual event includes several off-road distances that traverse the natural landscapes of the camp property. Participants can choose from a variety of course lengths that navigate through local forests, canyons, and pastures, specifically featuring spring wildflowers during this time of year.
The following distances are available:
- One-Mile Fun Run
- 5k Run
- Manchester 10k
- Half Marathon
The Half Marathon course leads runners through diverse terrain, including wooded areas and open pastures. The 10k and 5k events utilize the camp's trail system, while the One-Mile Fun Run is a family-oriented course that circles Lake Echon. All ages are permitted to participate in the 5k and the One-Mile Fun Run.
Registered participants receive a t-shirt, though specific size availability depends on the registration date. In the 5k, 10k, and Half Marathon categories, trophies are awarded to the top male and female finishers. Early bird pricing is available for several distances if registration is completed by mid-March. Visit the organization's website for the most recent information.
