Race Registration  

The MAD Backyard Ultra is brought to you by the Chattanooga Track Club and the Locomotion Endurance event's race director. In 2022, MAD backyard ultra was slotted as a bronze ticket event for The Big Dog's Backyard Ultra. Last year's winner earned a free entry into Ohio's Backyard Ultra. In 2023, a course record was set with 132 miles. Participants will run a 4.1667-mile loop every hour until only one person is standing. You have one hour to finish the loop once it has started. If you finish a loop within the hour, you may start the next hour’s loop, provided you are in the start corral when the next hour starts. If you do not finish within the hour, you are out of the race and considered a DNF. Crew access is available at the start/finish. Tents and Canopies are allowed near the start line. We will give you a 3-minute, 2-minute, and 1-minute warning to get lined up for the next loop. All runners are required to be in the starting corral before the top of the hour. Failure to line up in the starting corral will result in disqualification of the runner. Participants must start a new loop at the sounding of the bell starting the loop. Once you are on the course, you are not allowed any aid from your crew or any other individual. No non-competitors on the course (including eliminated runners). Except for restrooms, competitors may not leave the course until each loop is completed. Runners are responsible for their aid on course. You must be on and stay on the course unless you need to use the bathroom. No artificial aids (including trekking poles) are allowed. Once you are back to the start and assuming you have finished within the hour, you may use the bathroom, eat, drink, sleep, ponder the next loop, etc., but you MUST be back in the start corral at the beginning of the hour to continue into the next hour’s loop. Runners will continue until ONE runner completes a FINAL lap. (i.e. If there are two runners left and one does not complete the loop, then the one that completed the loop will be declared the winner). No pacers whatsoever. The MAD race volunteers and workers will provide aid at the start/finish line.
