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.

The competition heats up when the players learn that whoever loses 2% of their body weight first this week gets immunity. The catch is that only one person gets immunity and they only get one shot to weigh in whenever they think they've reached that goal. Later, the players head to the pool for a swimming challenge involving weights. After each contestant finishes the race, they are allowed to go back and help others finish, which proves very revealing about who the players want to stay in the game -- and who they don't.
