The stakes are higher than ever when the five final players compete in a "Biggest Loser" first -- a sprint triathlon, requiring them to swim a mile, bike 12 miles and run three miles. The triathlon winner will secure a coveted spot as a finalist, as ... (more)well as a brand new Ford Fusion. Then it's an emotional trip down memory lane as the contestants watch footage of their journeys with their trainers, and see firsthand how far they've come since arriving on the ranch. Later, it's time for the last weigh-in before the finale, where two players will fall below the red line and go home, and two more will become finalists, joining the triathlon winner to compete for $250,000 and the title of "The Biggest Loser" at the season 15 finale.
