Season 3’s Trick Stairs
The Trick Stairs are an obstacle, used as the first obstacle in the Qualifier during episode 10 of Season 3.
It is a tumbling staircase with six blocks that contestants must climb down, grab a trapeze bar, and swing across the water to the next obstacle.
It was replaced by the Door Knock (which was used as the first obstacle in the Qualifier during episode 3 of the same season) in the next episode.
