The Skull Games Challenge – Lake Carl Blackwell

The Skull Games Challenge is a unique endurance trail event held alongside The Next Loop Endurance Series at Lake Carl Blackwell in Stillwater, Oklahoma. Participants can choose a 25K or 50K loop-based trail race, with an added twist — optional challenge stations between loops designed to test strength, resilience, strategy, and problem-solving.
We're also adding a TEAM Division: 4 person team for the 50K Challenge. Team must travel all 10 loops together. All Team Members must complete at least 2 Challenges. All Male/Female/Coed are scored together. Best Team Wins...period
These optional tasks may include physical efforts, tactical challenges, and mental problem-solving elements. Attempt a challenge and earn time credit; complete it successfully and earn even more. Whether you focus purely on the run or incorporate the challenges into your race strategy, this event delivers a fresh endurance experience that blends trail running with adaptability, grit, and community.
This event is designed for runners looking for something beyond a traditional race — a supportive atmosphere, a memorable challenge, and an opportunity to push limits both physically and mentally.

Event's current local time: 3:18 AM CT
