SALT LAKE CITY — Utahn Karson Voiles, a gym owner who is competing on NBC's "American Ninja Warrior," completed the first stage of the finals with enough time to spare on the episode that aired Monday, Sept. 11, from Las Vegas.

That qualifies him to compete in the next round and potentially win the title of American Ninja Warrior and the $500,000 prize. He ranked 33rd of the bunch with a time of 2 minutes and 21 seconds.

The fastest contestant, Drew Drechsel, completed the obstacle course in 1 minute and 30 seconds. The slowest finisher, Nick Hanson, completed the course in 2 minutes and 30 seconds.

There were 41 finishers who will advance to the next round, making it the most ninjas in the history of the show to continue onto stage 2 next week.

The first stage required each of the contestants to jump onto a moving propeller, complete a parkour run, jump across moving pipes and complete other complicated obstacles.

Ryan Souter, a contestant from Utah also on the show, will not advance to the next round.
