The Paddle Boards is an obstacle, firstly introduced as third obstacle on American Ninja Warrior 7 in Orlando, and then returned on:
- American Ninja Warrior 8 in Philadelphia as the third obstacle, and
- American Ninja Warrior 9 in Denver as the fourth obstacle.
It consisted of 6 paddles (3 on each side), supported by a center axis. Competitors must maintain their balance while running across the paddles (in a similar fashion with the Bridge of Blades or Rokudantobi). Also, competitors were not allowed to touch the obstacle with their hands or step on the center axis. If they did so, they would be disqualified.
On American Ninja Warrior 8, the obstacle was modified by adding a barricade on top and making the center axis wider. 31 competitors failed on this obstacle during Philadelphia qualifiers, including Abel Gonzalez.
Then, on American Ninja Warrior 9, the obstacle was modified once again by adding two more paddles (for a total of 8 paddles, 4 on each side). 8 competitors failed on this obstacle during Denver qualifiers.
During Denver finals, three competitors were eliminated on this obstacle. Most notably, it took out Sam Sann, when he stepped on the center axis, resulting a disqualification.
The Paddle Boards appeared on Ninja Warrior UK 2, as the third obstacle in the finals' Stage 1. However, this obstacle was unexpectedly proven to be much brutal than on American Ninja Warrior, eliminating 9 out of 14 competitors who attempted it, including top competitors such as Tim Champion and Teige Matthews Palmer.
Although most simply fell from the rotating paddles, several were disqualified for stepping on the center axis (e.g. Tim Champion).
Several of the obstacle's victims attributed their fails to a wave of "paddle-panic", as the remaining competitors were forced to watch their fellow competitors failed in huge numbers.
