Piston Road

The Piston Road is an obstacle, firstly introduced as the first obstacle in Stage One on American Ninja Warrior 6, replacing the Timbers from the previous season.

Competitors must across 6 angled piston-shaped steps (in a similar fashion to the Godantobi or Rokudantobi). This obstacle was proven to be extremely easy, as all 90 competitors could complete the obstacle.

American Ninja Warrior 7
The Piston Road returned on American Ninja Warrior 7, once again as the first obstacle in Stage One. This time, the obstacle took out 4 competitors (Steve Martin, Dennis Lappin, Caitlin Shukwit and Annie Dudek). Despite that, it still had a very low 4% knockout rate.

On American Ninja Warrior 8, the obstacle was replaced by a more difficult obstacle (the Snake Run).

Ninja Warrior Poland
On Ninja Warrior Poland 5, the Piston Road appeared as the first obstacle in the Semi-finals and finals Stage Two. In this season, the obstacle consisted of three pistons.
