World First - Obstacle Grading System

N scale grading system helps define obstacle difficulty

Obstacle Grading System

January, 6th, 2020 - You will start to see some new graphics around the Ninja Nation arenas. These graphics represent our Obstacle Grading Program. We love obstacles but realize it can be challenging to figure out just how hard each obstacle can be. To help with this, we are launching our world-first Ninja Obstacle Grading Program.

Each obstacle will now be graded within our “N” Scale of grading. Similar to what you would find in a climbing gym with their “V” scale, the “N” (or Ninja!) scale starts at N1 and progresses all the way to N10. All of our mainstay obstacles will have grades on them, and the grades will be posted on the padded columns at the start of each obstacle. As we roll out this project we will grade each and every obstacle in the arena, except for the daily soft play courses designed by our coaches in the middle of the arenas.

Grading obstacles is a totally new concept. It is also very subjective and not meant to be exact, as all ninjas are different. Our entire coaching team has helped determine the difficulty of each obstacle, but we are sure there will be changes as the program matures. We welcome any feedback you wish to provide.

Please use the grades to find obstacles within your skill range, and to find an obstacle you can progress towards!
