Registration closes on Nov 20, 2026. The event is organized by the Chattanooga Track Club as part of the Circle Series.
Format and rules
Runners circle the track continuously, and final results are based on total laps completed within each time limit. Each completed lap is credited as 0.25 miles; participants should expect watch mileage to be higher than track mileage. The event is cup-free; runners must bring their own hydration systems. Volunteers will staff an aid station with drinks and snacks, but runners are responsible for their own food and hydration. Littering may lead to disqualification.
Crew support is allowed every lap from a designated infield area near the start line. Pacers are not permitted unless they are registered participants. Race officials may evaluate and withdraw runners at any time for safety reasons.
Logistics and awards
The venue is turf; small tents are permitted without tent stakes and must be weighted. A small RV/car camping section is available near the stadium. Lodging options are listed for Ringgold, GA.
Awards include top three male and female in each distance, top male/female masters and grandmasters, and special recognitions for specific distance milestones (6 hour - 50K, 12 hour - 50 miles, 24 hour - 100 miles). The event is part of the Chattanooga Ultra Championship series. Visit the organization's website for the most recent information.
