The Sweaty Backyard Cox Ultra

Concord, United States • 25 Jul 2026

The Sweaty Backyard Cox Ultra takes place in the woods around Concord, NC, as a Backyard Ultra. The format follows the loop structure: a 4.167-mile loop that each participant must finish within one hour, with loops beginning after the previous loop completes and no late starts. The course uses a fixed starting corral and prohibits non-participants on the loop, while allowing standard aid stations and prohibiting artificial aids.

The race is open-ended with a tough, no-frills atmosphere. This year it is a Bronze-level qualifier for the 2026 Capital Backyard Ultra in Lorton, Virginia; the finisher’s entry fee is covered. Timing is optional; the winner is the last to complete a loop. Visit the organization's website for the most recent information.
