It's the last episode before the season finale, and time for the final four contestants to reflect on their weight loss journeys and the amazing progress they've made. They'll try on their former "big" clothes and watch highlight videos with their trainers showing just how far they've come. Then, in their final challenge of the season, the contestants will have to carry all the weight they have lost as they race around a track, shedding one week's weight loss at each pit stop until they cross the finish line. Later, at the final weigh-in, two players fall below the yellow line, and then make their heartfelt pleas to viewers, as America will once again decide which of the two will become the third finalist at the season finale.
