Ninja leagues, explained
Ninja is much more than a TV show. Kids, teens and adults compete in real leagues every weekend, at gyms across the country and around the world. Here is how the main leagues work, who they are for and how your athlete can start.
What is a ninja league?
A ninja league is an organization that runs a competition season: local gyms host qualifying events on their own obstacle courses, athletes compete in divisions by age, and the best qualify for championships.
Most leagues are open to beginners. There are no tryouts: an athlete registers for a competition at a gym, runs the course and gets a time and a placing. Divisions usually start around age 6 and go all the way to adults and masters.
