Trouble U's

The Trouble U's are a variation of the Fling Set, used as the fifth and final obstacle in the Qualifier during episodes 8 and 14 of Season 3.

Contestants must run across a narrow walkway and over two triangles while avoiding two W-shaped sweeper swings to reach the finish platform.

Much like every other variation of the Fling Set, nobody has ever made it across, mostly due to misunderstanding of the concept. Instead of jumping over the lowest part of the W's, most contestants tried to jump over the upward-facing triangle.
