The Sweaty Backyard Cox Ultra

Concord, United States • 25 Jul 2026

The Sweaty Backyard Cox Ultra takes place in Concord, North Carolina, as a Backyard Ultra–style race set in the woods. The course is a single loop of 4.167 miles that is repeated until only one runner remains. The event conveys a gritty, communal atmosphere with a humorous, tough-running vibe. New for this year, it is a Bronze-level qualifier for the Silver-level Capital Backyard Ultra in Lorton, Virginia, and the race winner earns entry fee coverage for 2026 Capital Backyard Ultra. Runners follow Backyard Ultra rules: each loop must be completed within an hour, no non-participants on the course, aid only at stations, no artificial aids, and standard passing rules.
