American Ninja Warrior In Las Vegas

Spoiler alert, if you don't want to find out what happened, stop reading.
From the Las Vegas Sun: In its four-season history, no one has ever completed all four stages of the "American Ninja Warrior” obstacle course, and producers have no plans to make it any easier for its fifth season, which filmed its finale in Las Vegas last weekend and premieres Monday on NBC.
In fact, they plan to make it harder. Instead of featuring the same course in each city, the show challenges its fifth-season competitors with an entirely new set of obstacles in each regional competition.....
The upcoming season is more than just a tease, however, as Weed hints that the Las Vegas competitors push new boundaries and come closer than ever to conquering the four stages laid out on the course set across from the Luxor, which took three weeks to build, two weeks to light and four days to test before the final round of contestants was unleashed.

In reality, no one even came close to even getting to the 4th stage, from a witness who was there.
