The Sweaty Backyard Cox Ultra
The Sweaty Backyard Cox Ultra is a backyard ultra held in Concord, NC at 3702 Sapp Rd on July 25, 2026. The event uses a loop course measured at 4.167 miles. Each loop begins precisely one hour after the previous loop and must be completed within that hour to count.
Participants assemble in a starting corral that remains the same size for the duration of the event. Runners must be in the corral at the bell and must start each loop at the bell. A three minute, two minute, and one minute warning is given before each loop.
The event follows standard backyard ultra rules: runners may not leave the course until a loop is finished except for restroom use, no personal aid is allowed during a loop though common aid stations are provided, and non-participants are not permitted on the course. Artificial aids, including trekking poles, are not allowed. Slower runners must allow passes.
Timing of individual loops is optional. The winner is the last person to complete a loop; all other participants are recorded as not finishing. If no runner completes one more loop than everyone else, no winner is declared.
This event is a Bronze level qualifier for the Silver level 2026 Capital Backyard Ultra in Lorton, Virginia. The finisher of this race will have their entry fee covered for that Capital Backyard Ultra. Visit the organization's website for the most recent information.
