Flow Courses are all about perfection! Athletes are judged by their ability to make it through obstacles in a given course and get from platform to platform without falling off the obstacle! Once an athlete falls off an obstacle, that is it! In this format, athletes are ranked by the number of obstacles they complete in succession. If multiple athletes are tied for the same number obstacles in succession, the athlete who completes those obstacles faster will be ranked higher!

Challenge courses are the newest ninja competition format! This is a twist on the Flow Course format. Athletes get multiple attempts throughout their course run to figure out spots where they have fallen. Athletes are allowed to retry two obstacles per Challenge Course. However, athletes may only retry a failed obstacle one time. The athlete must complete the failed obstacle on their subsequent attempt in order to progress through the course. Once the athlete has used up their 2 retries or fails a retry attempt, the run is over.
