The Sweaty Backyard Cox Ultra

Concord, United States • 26 Jul 2025

The Sweaty Backyard Cox Ultra is a challenging backyard ultra event held in the woods of Concord, North Carolina. The race features a 4.167-mile loop that participants must complete every hour, with the event continuing until only one runner remains. This open-ended format tests endurance and strategy, as runners must start each loop precisely on the hour and complete it within 60 minutes. The event is a Bronze-level qualifier for the 2026 Capital Backyard Ultra in Virginia, with the winner receiving a covered entry fee for that race. The course emphasizes self-sufficiency, with no personal aid allowed during loops and strict rules to ensure fairness and safety. Visit the organization's website for the most recent information.
