The Colorado Ninja League (CNL) is dedicated to growing the sport of Ninja Obstacle Competition by creating an exciting, inclusive, and professionally organized competitive experience for athletes of all ages and skill levels.

​

As a Colorado-based non-profit organization, our mission is to provide a fun, fair, and supportive league where athletes can challenge themselves, build confidence, develop sportsmanship, and become part of an incredible ninja community. Through competitions hosted at premier ninja gyms across the state, we strive to inspire personal growth, celebrate achievement, and foster lifelong friendships.

​

Every athlete is welcome—whether you're stepping onto a course for the very first time or competing at an elite level. Every registration directly supports the league and goes back into athlete prizes, awards, and creating an unforgettable season for our competitors.

 

Together, we're building Colorado's strongest ninja community—one obstacle at a time.
