The Skull Games Challenge

The Skull Games Challenge

The Skull Games Challenge on November 21, 2026 at Lake Carl Blackwell in Stillwater, OK is a loop based trail event created through a partnership between The Next Loop Endurance Series and Skull Games Solutions. The format blends trail running with resilience and tactical problem solving.

Participants choose between the following distances:

• 25K loop based trail race
• 50K loop based trail race

Optional challenge stations are positioned between loops. Tasks at these stations may include strength efforts, mental focus exercises, grappling or skill challenges, sandbag work, pushups, and real world problem solving scenarios. Attempting a task can earn time deductions while successful completion earns greater credit toward overall finishing time, introducing a strategic element alongside endurance performance.

The event description highlights both physical and decision making demands on course and notes an emphasis on building community on the trails. The combination of loop format, optional tasks, and time credit mechanics creates choices about pacing and task selection during the race.
