Kayla the fourth-grader is up first, and Jim, Bryan, and Nicole face off against her. Jim thinks about his own daughter, who is athletic, and is worried. As they start off, Kayla takes some kind of a fierce lead. Sami says, "She smoked the team! Eat her dust!" Wow, she really has the objective-but-supportive thing down, doesn't she? Jim says that there are a lot of hormones in the meat these days. ...That's what she said.

The third-grade heat involves Kae, Bill, and Phil. They all talk about how much they'd like to call home. Jim gives Jack the third-grader a good run for his money, and ends up winning! Woo! Phil would take the grand prize on Are You Faster Than a Third-Grader? for sure.

Finally, it's the kindergarten heat with Cooper, who really looks like a combination of the youngest, drumming Hanson and Bjorn Borg. He's really adorable. It's Ryan, Amy, and Hollie who compete against him. And let me tell you, Cooper is awfully fast. Ryan puts up a good fight, but in the end, he can't overtake the half-pint, because he's had too many half-pints of heavy cream. Hollie says it was amazing that a five-year-old could run that fast, and also quite embarrassing. In any case, the Red Team wins! It's their third challenge victory, but as Bryan notes, challenge wins aren't as important as weigh-ins.

And then, phone calls home! Cowboy David talks to his wife, whom he misses. No wonder! His wife looks like a hottie. We see video of his kids, and David says that even though he misses all of them, it's worth it to be there. His baby just started crawling. Awww. He tears up as he gets off the phone. Bryan talks to his girlfriend, and he also starts crying. She's cute, too! Do you think these girlfriends/wives have to be on top all the time? I mean, otherwise they'd get crushed, right? Oh, shut up, you know you were all thinking it. Amy talks to her daughter, who asks why she's crying. Amy says it's because she misses her so much. Aww, this is so sad! And then Phil talks to his wife and starts bawling. She's crying, too. She says that she's fine, but not having him there is harder than she thought. She then tells their daughter to tell Phil that she misses him. Well, that's genuine. Phil tells his wife that he's doing this so he can be around longer for his daughter. Oh, so much crying! It's like everyone's become Patty all of a sudden. I'm bored. Where's Jillian?

The contestants on the Blue Team next go for a hike on a really steep hill. Jerry seems to have recovered from his leg injury. There is lots of huffing and puffing, and Ryan doesn't look like he's going to make it. Patty says that it was great to see Ryan overcome his fear of going up the mountain and then going back down. He tells us he was scared the entire way. He does keep slipping. But, I mean, it's not like there are landmines or anything. Buck up, man. Bob says that he believes the Blue Team is stronger than any other team in the house. He's hard on them, and is expecting the best out of them. He's also proud of what they've been able to achieve. The team makes it to the top, and Patty says that it was all worth it, and it made her realize how phenomenal it is to lose weight. She adds that she would have never had this experience at her previous weight.
