Event Overview

The Circle Endurance Event is a timed track race at Ringgold High School in Ringgold, Georgia. It offers participants the chance to run continuously for 3, 6, 12, or 24 hours, aiming to cover as much distance as possible within their chosen time limit.

Event Format and Rules

Participants run laps on the track. Each lap is credited as 0.25 miles. Crew support is allowed from a designated area in the infield, but pacers are only permitted if they are registered participants. Runners must bring their own hydration systems as it is a cup-free event, and are also responsible for their own food and water, though an aid station with drinks and snacks will be provided. Runners can set up a personal "pit area" with a small tent, but tent stakes are not allowed on the turf venue.

Littering on the course can lead to disqualification. Final results are calculated based on the total number of laps completed. Race officials may evaluate a struggling runner and decide if they can continue for safety reasons. Courtesy rules state that all runners have the right to the inside lane and should run single file in the inside lanes to allow others to pass safely.

Awards

Awards are given to the top three male and female finishers in each distance, as well as top male and female masters and grandmasters runners. Special awards are presented for reaching specific milestones: 50K in the 6-hour event, 50 miles in the 12-hour event, and 100 miles (a belt buckle) in the 24-hour event.

Series Information

The event is part of the Chattanooga Ultra Championship Series, which also includes the MAD Backyard Ultra and Locomotion Endurance Event. To be eligible for series awards, participants must compete in all three races. Awards are given for participation, for completing at least a 50K in each race, and for the top three male and female runners with the most total mileage across all events.
