And then it's challenge time! On a bridge! Sami tells the contestants that they're in between two lives: the sucky, fat one, and the happy, skinny one. There is a bridge that will bring them from one side to the other, and it is built of challenges. The specific, literal challenge on this bridge is 250,000 pounds of sand. The teams must race over the bridge, across the sand to their team's colored flag, and then back. The top five teams after the first heat will go to the second round, and the top two teams from the second round will go head to head for the victory. The winning team will get immunity at the weigh-in. This is obviously huge, thus befitting the theme of the season.

Some of the contestants positively leap over the sand pile, while others have a bit of a harder time. The team members have to get their flag together before they can race back, so if there's one fast team member they can't just sprint ahead and win the whole shebang. Jerry makes it over the sand pile while maintaining consciousness, which is a victory in itself. The five teams to move on to the second round are the Yellow Team, the Black Team, the Blue Team, the Green Team, and the Red Team. They all look pretty tired, but get back to the start line and prepare to tread some sand. Once again, both members of the team have to cross the finish team to win, and it's the Yellow and Black Teams who made it to the third heat. Tara, though supportive to dead weight Laura, interviews that it sucks that Laura gave her best, but her best wasn't good enough. Tell it to James Ingram, honey. The Black Team totally doesn't want to be beaten by girls in the finals, which makes me hope even more that they will be. In the end Blaine pulls far ahead, and Mandi is first to cross the finish line for Yellow. This leaves Aubrey versus Dane, and let me tell you that Aubrey totally hauls ass! Dane realizes that she's catching up, and really wants to win it for his kids at home. And he does. Oh, rat. Aubrey gave him a run for it, though! The Black Team has immunity, and is feeling pretty happy about it.
