Christopher Lange is a history/political science teacher who first competed in Kansas City in American Ninja Warrior 7.
In qualifying, his run was cut but it was revealed that he completed the course placing 25th. In the city finals, his run was digested but it was shown that he failed the Floating Tiles. He placed 36th overall, and did not make it to the national finals.
Lange returned in American Ninja Warrior 9, once again in Kansas City. He now sported his new "short shorts" believing that it would get him to Vegas.
Lange was the first runner of the night, and was able to get through the Floating Steps, and was able to get extra leg grip on the Hang Glider, but like in the city finals two years ago, he failed the third obstacle. He became the first of many that night to fail the Broken Pipes.
