The Skull Games Challenge - Lake Carl Blackwell
The Skull Games Challenge is a looped trail endurance event held at Lake Carl Blackwell in Stillwater, Oklahoma on May 23, 2026. The course is offered in loop format and is presented alongside The Next Loop Endurance Series. The venue is listed at 11000 W Hwy 51 in Stillwater.
Participants choose between two loop distances:
- 25K loop based trail race
- 50K loop based trail race
Optional challenge stations are placed between loops. These stations include physical efforts, tactical tasks, and mental problem solving. Attempting a challenge awards a time credit; completing a challenge successfully awards additional time credit. Runners may choose to focus only on running or to incorporate challenges into their race strategy.
A team division is available for the 50K distance. Teams consist of four people who must travel all ten loops together. Each team member must complete at least two challenges. Male, female, and coed teams are scored together.
Registration for the event closes on May 22 at 11:59 PM CT. The event format emphasizes repeated loops, optional inter-loop tasks that affect time, and a team option with specific requirements. Visit the organization's website for the most recent information.
