Shawnee Hills 100

Sat, Aug 24 – Sun, Aug 25, 2024

3760 Ondessonk Rd., Ozark, IL 62972

Shawnee Hills 100 Mi, 100K, 50K is an entire weekend of outdoor and trail running fun for, not just the runners, but their family and friends!

There will be miles and miles of great running through the beautiful Shawnee National Forest, the best food, a plethora of free beverages, and swag to give away. We will also have the kids Fun Run, vendor expo, and the totally rustic Camp O cabins.

Camp Ondessonk, in the heart of the Shawnee National Forest, will play host to the Shawnee Hills 100 race. The runners will get to explore some of the most stunning and extraordinary rock formations and waters falls that Shawnee National Forest is well known for. The course will take you deep into the sandstone canyon systems of Southern Illinois' Shawnee Hills Natural Division while traversing Jackson Hollow, the Bay Creek Reservoir and several waterfalls along the course, including Pakentuck Falls (the tallest free-falling waterfall in Illinois), Jackson Falls, Horseshoe Falls, and Cedar Falls; along with some inspiring views from Salomon's Ridge.
