S15, E12: The contestants are off on the adventure of a lifetime, headed to Utah Olympic Park in Park City, Utah, where they'll train like champions and get to meet some incredible Olympic athletes. Dolvett introduces the players to Olympic gold medalist Apolo Ohno, who talks about his own "Second Chance" - this season's theme - and works out with the contestants inside the spectacular Olympic Oval arena. Then the contestants get to compete in the sport of curling, after an introduction to USA Curling team members Jessica Schultz, Debbie McCormick and Anne Swisshelm. The fun continues at the base of the bobsled track, where words of motivation from USA Bobsled Team members Lolo Jones and Jazmine Fenlator get the remaining seven players fired up about the fast-paced sport. But for this week's challenge, they won't be racing down the track. Instead, they will be running more than a mile up the bobsled track, a challenge made far more difficult by the elevation of over 7,000 feet. Also this week, Bob designs an Olympic-inspired workout that puts all the players to the test, and Jillian tries to help a contestant still struggling to embrace her self-worth. Travelling and being away from the ranch environment leaves many contestants worried about their weight loss this week. Those fears intensify at the weigh-in, where surprising results push two players below the yellow line and the other contestants must decide which player is going home.
