The Biggest Loser: Season 13, Episode 16

13 - 16:

This week, a surprising turn of events shakes up the competition, and the contestants compete in a rough and wild short version of a "Tough Mudder" competition. But they won't be doing it alone - with them will be the show's three most recent winners John Rhode, Olivia Ward and Patrick House. Host Alison Sweeney helps motivate the remaining contestants by telling them the player with the highest percentage of weight loss at the weigh-in will win a Ford Escape SUV. Later, the players stroll down memory lane with the trainers and watch video journeys of how far they've really come from their first day on the ranch before an emotional weigh-in determines which player will walk away with a brand new car.
