Three loops of 10 mile trail through forest, hills, and meadows at Clinton Lake State Recreation Area. Almost all single-track trail except for small section on road & bridge that connects two sides of the trail loop around the lake. About 1500 feet of elevation gain per loop. This is considered a challenging trail for Central Illinois, and has been used by MANY MANY MANY ultra runners to train for mountainous races in Kentucky, Georgia, South Carolina, Utah, Colorado, and Montana. Two fully stocked aid stations on each loop. Kick off your spring racing season on our beautiful trail!

2025 direction: All runners will be running in the same direction, counterclockwise - short side first!

Awards and Swag:

The top three male and female runners will each receive special awards. All runners will receive a shirt of some sort and a finisher item.
