Ozark Foothills Endurance Runs - April 9-11, 2027
Ozark Foothills Endurance Runs is a multi-distance trail running event in Wildwood, Missouri, held at 4515 Hencken Road and organized by Terrain Trail Runners. The event program includes a range of distances from a kids fun run up to a 100 mile race. Registration opens May 22, 2026, and is scheduled to close March 30, 2027, or when field limits are reached. Online registrations made after March 14, 2027, will receive alternative event swag instead of guaranteed swag.
Entry fees are listed in tiers, with a published range from USD 100.25 to USD 349.32. The event lists two price increase dates for several distances: a first tier increase after September 27, 2026, and a final tier increase after February 28, 2027. The Night-50K distance is exempt from price increases. Deadlines for distance changes, registration cancellation, and pacer registration fall on March 28, 2027.
The event participates in the Trail Mix Fund program, which pays race registration fees for eligible participants to reduce financial barriers and support greater diversity in trail racing; this partnership began in December 2025. The organizer publishes race policies covering refunds and other rules. As part of a sustainability pledge, the races are cup-free and participants are asked to bring their own mess kit to reduce single-use waste.
