The Sweaty Backyard Cox Ultra
The Sweaty Backyard Cox Ultra is a Backyard Ultra event on July 25, 2026, held in Concord, NC at 3702 Sapp Rd. Registration closes on Thu, Jul 23. The event uses an open-ended format with no fixed finish distance.
The course is a loop of exactly 4.167 miles. Each loop is governed by Backyard Ultra rules: a fixed starting corral that remains the same size, an hourly loop schedule with warnings three, two, and one minute before each start, and a requirement that all participants start at the bell. Participants may not leave the course until a loop is completed except for restroom use. No non-participants are allowed on the course and no personal aid is permitted during a loop; common aid stations are allowed. Artificial aids, including trekking poles, are prohibited. Each loop must be completed within one hour to count, including the final lap. Timing of loops is optional.
The winner is the last person to complete a loop; all others are recorded as not finishing for the purposes of victory. Results list each runner by distance covered. If no runner completes one more loop than everyone else, there is no winner. Visit the organization's website for the most recent information.
