American Ninja Warrior 1[]
In the premier season of American Ninja Warrior, Gunner Bahn had traveled all the way from Alaska to be there. His debut didn't go to plan however, as he was all cut and failed the Rope Swing.

Undeterred by his past performance, Bahn made the flight to California once more to compete. His run was all cut, but he had seen a large improvement. He got revenge on the Rope Swing but couldn't summit the Warped Wall.
American Ninja Warrior 3[]
For his third season, Bahn was determined to clear the course. His qualifying run was all cut, but he had moved quickly through the first five obstacles. Unfortunately for Bahn, history repeated itself. For the second year straight, he couldn't mount the Warped Wall.
American Ninja Warrior 4[]
Entering season four, Bahn was selected to compete in the Northwest regional. His qualifying run marked the first time he was shown on TV, as he was digested. He cleared the qualifiers for the first time with the 11th fastest time. In the Regional Finals Bahn was once again all cut. He had took a few tries on the Warped Wall, but unlike previous seasons, he completed it. Bahn cleared the Regional Finals with the 14th fastest time, barely surviving. In Vegas, Bahn received his first ever fully broadcasted run. He was the first Alaskan to ever compete on the show and NBC highlighted his life in Anchorage. He was piecing together a promising Stage One run up until he slipped on the Half-Pipe Attack. He has not competed since.
