After Vicky is voted off campus following the latest weigh-in, the remaining contestants learn that they will be traveling to Dallas, Texas, one of the unhealthiest cities in the United States, to help the legions of unfit there start on the path to good health. They act as motivators for those participating in a five kilometer walk/run starting and ending at the Cotton Bowl. The contestants participate in a reward challenge apropos to being in Texas, the winner to receive immunity for the week.

The last chance workout is less two contestants who head home to deal with a family issue, but they return to Dallas in time for the weigh-in at the American Airlines Center.
