The Skull Games Challenge - Nov 2026

The Skull Games Challenge is a November trail race at Lake Carl Blackwell in Stillwater, Oklahoma, offering 25K and 50K distances on a loop course. The race includes optional challenge stations between loops, requiring runners to manage miles and decide if a task is worth the effort for a potential time deduction. These stations may involve strength work, mental focus, grappling or other skill tests, sandbag carries, pushups, and practical problem-solving scenarios. Successfully finishing a task earns a greater credit toward overall time than merely attempting it, making strategy a component of the race. The event stems from a partnership between The Next Loop Endurance Series and Skull Games Solutions, designed for runners seeking a trail day that also assesses adaptability, teamwork, and grit.
