Ninja sport includes short events, involving courses between 25 metres and 200 metres in distance that contain many technical obstacles where individuals or teams of athletes race against the clock or head-to-head to complete the course.
Events have been popularised across the world by the TV shows: Ninja Warrior/Sasuke; and Ultimate Beastmaster. Courses may be indoor or outdoor and involve suspension, balance and climbing obstacles. Obstacle difficulty is emphasised therefore course completion is the primary goal and secondary to this is the speed of completion. To this end, failure of an obstacle can result in elimination from a tournament.
