This week, the contestants return to their hometowns to visit family and friends. But with those happy reunions comes the challenge of continuing to eat right and exercise despite all of the distractions and temptations away from the ranch. After arriving home, the players also get a surprise - a gift crate with a stationary bicycle and a DVD of host Alison Sweeney explaining the at-home temptation and challenge that awaits them. Each contestant will ride the length of a full marathon (26.2 miles) on their new stationary bike - but they are also provided with a temptation in the form of 48 mini-cupcakes. For every cupcake a contestant may choose to eat, they can apply five minutes to the final ride time of any other player during the bike challenge - a twist that could have a dramatic impact on the outcome of the game. Later, the weigh-in back at the ranch reveals how they all did at home before another contestant is eliminated and sent home for good. Trainers Bob Harper and Jillian Michaels also star.
