4 Fore 30 Infinity Backyard Ultra
The 4 Fore 30 Infinity Backyard Ultra is an endurance running event held in Macks Creek, Missouri. Following the Big's Backyard Ultra format, runners complete a 4.1667-mile (6.7 km) loop every hour, starting at 7:00 AM, with each loop beginning precisely on the hour. Participants must finish each loop within the hour to continue, and the race continues until only one runner remains.
The course is a loop or out-and-back, with an aid station near the start-finish line. The event features a supportive atmosphere, race swag for all runners, and benefits the Kids' Harbor Child Advocacy Center. Lighting is provided, but headlamps are recommended for night running.
