Event overview
Ozark Foothills Endurance Runs takes place in Wildwood, MO at 4515 Hencken Road. The event weekend features multiple trail race distances and related activities. Registration opens June 6, 2025 and closes March 29, 2026 or when field limits are met. The race is part of the Trail Mix Fund program and joined that fund in December 2025. The event follows a zero-waste approach: it is cup-free and participants are asked to bring a mess kit (plate and spork) because paper and plastic serviceware will not be provided.
