The Downhill Pipe Drop is an obstacle, firstly introduced as the second obstacle on American Ninja Warrior 6 in Miami.
Competitors must slide the red pipe, then time their release to grab the rope, and then transition to the landing platform to advance.
Since there were 42 competitors who completed the Miami qualifiers course and advanced to Miami finals, during Miami finals, the rope was placed 6 inches further than during Miami qualifiers. As the result, the obstacle took out 6 more competitors, including Drew Drechsel (making it his first early exit from the competition).
A similar version of this obstacle (called as the Big Dipper) would later appear as the second obstacle on American Ninja Warrior 7 in Kansas City and American Ninja Warrior 8 in Atlanta, except the track was curved and the rope was replace with the cargo net.
The Downhill Pipe Drop appeared as the second obstacle during the finals' Stage 1 on Ninja Warrior UK and Ninja Warrior UK 2. However, this obstacle was called as the Pipe Slider (not to be confused with the Pipe Slider from SASUKE).
On Ninja Warrior UK, the obstacle took out 3 out of 14 competitors who attempted it, including Katie McDonnell (who was the only woman to reach the finals). While on Ninja Warrior UK 2, the obstacle took out Corbin Mackin (who was the only competitor to fail at this obstacle).
