The Sweaty Backyard Cox Ultra - Concord, NC
The Sweaty Backyard Cox Ultra is scheduled for July 25, 2026, at 3702 Sapp Rd in Concord, North Carolina. The event uses the backyard ultra format with a single loop course laid out in the woods near the address given.
The course is exactly 4.167 miles per loop. Each loop starts precisely one hour after the previous loop; a warning is given three, two, and one minutes before each start. Participants must be in the starting corral at the bell. The corral is sized to fit the entire starting field and stays the same size throughout the event.
Rules for loops include that participants may not leave the course until each loop is completed, except for restroom use, and no personal aid is allowed during a loop while common aid stations are permitted. Artificial aids, including trekking poles, are not allowed. Slower runners must allow passing. Timing of individual loops is optional.
The winner is the last person to complete a loop; all other entrants are recorded as DNF for the win determination. Results are reported as distance covered by each runner. If no runner completes one more loop than all others, there is no winner. The event is open ended. Registration closes July 23 at 11:59 PM ET.
