Nestled around a finger of Cherokee Lake, Panther Creek State Park presents the perfect back drop for this fall ultra-marathon. Offering 12 and 24 hour races, the Dirt Circuit is sure to deliver a challenge to runners of all backgrounds and abilities. For this spectator-friendly race, athletes, vendors, family, and friends are encouraged to enjoy the fun at Base Camp throughout the weekend. You pick where your finish line is.

The Dirt Circuit is 3 miles of trail mostly resembling that of a cross country course. The loop course is a combination of wide and single track trails through fields and woods with two wooden bridge crossings. The course winds gently around the park offering many scenic views of Panther Creek. The Dirt Circuit starts and finishes at the soccer fields, which serve as Base Camp for the weekend. 

The 12 Hour Day Race and 24 Hour Race both start at 8:00 am Saturday. The 12 Hour Night Race will start at 8:00 pm on Saturday. The 24 hour race will continue through the night. The course will be marked with orange flags and tape for daytime use and glow sticks for when the sun goes down. Head lamps are strongly encouraged.
