GRAND JUNCTION, Colo. (KKCO) -- A local firefighter is hoping to become the first American to complete what's considered the world's most difficult obstacle course.
Scott Roahrig was selected to compete in the American Ninja Warrior competition and TV series. The ninja warrior competition started in Japan and has yet to be completed by an American.
Roahrig says his sons inspired him to try out.
"My kids are all my motivation. Everything I do, I think I almost do to prove to them that I can still do it and that I'm not just some old guy. They always push me and they're always pushing the envelope," Roahrig says.
Roahrig will start competing this Sunday in Denver. If he completes round one, he'll go on to round two on Tuesday. If he completes both of those, he'll go the finals in Las Vegas, which will be filmed in June.
The season of American Ninja Warrior starts July 1 on NBC.
