The teams have split to Black and Blue this week and there are mixed feelings in the house. Immediately after the pop challenge, while speaking to his new "Blue" team Ron jokes, "I'm putting a stripe down the middle of my room," referring to Mike being on the Black team.
Helen says, "We are so happy coming into the gym, we are going to be crying coming out of it." If she only knew how true that would be! The challenge lives up to its name as the longest challenge in Biggest Loser history, and the contestants fight to stay awake. Filipe sings about being Tongan and dances as he pedals, energizing himself with his culture. Kristin eats an apple to keep herself alert while pedaling at 3:00 in the morning, but Mike on the other hand has his hands tucked under his armpits and his eyes closed, at least pretending he can be sleeping. In an effort to not fall asleep, Mike and Kristin begin playing rock, paper, scissors, trying to work themselves mentally as well as physically. Meanwhile, Dane tells Aubrey in the midst of his own misery, "I feel like the number one criteria so far with these challenges is that we have to be miserable." After their new times are revealed and the Black team is ahead of the Blue team with only hours left in the challenge, the Black team yells in excitement and in contrast to what he was feeling before, Filipe says, "If I was wearing Blue now... I'd probably want to switch to Black." Aubrey is clearly upset at the outcome as she tells Mandy, "It's a good thing I'm here to lose weight and not win challenges... my optimism is gone... as far as winning... just going to focus on working myself out. With that attitude, Mandy refers to her sister as "Negative Nellie," but minutes later she is the one saying, "I hate winners... I want to punch them all in the face." With a lot of laughing, goofing around and playing games while on the bikes, and getting themselves through it with phrases like, "I am just going to keep pedaling the pounds away," the challenge finally ends. But as Aubrey admits the next day, "I started to freak out during the 24-hour challenge... I thought it was never going to end." Aside from a difficult week and even though almost everyone is on a different team, the contestants stay united, as is evident in some fun basketball they play.
