Rob is the final rider down the hill. He begins his journey with just under twenty minutes left. He doesn't look too steady on the bike, which Darwin notes. Partway back up the hill, Rob dismounts the bike and starts walking it, and then he starts retching. Darwin says, "This looks like strategery to me." That clinches it. Darwin is my favorite male contestant. Bill thinks that Rob would make a great Mole. In an interview, Bob says that Rob's performance made him a Mole suspect. Rob continues up the hill with seventeen minutes left. When Rob finally reaches the top, Anderson comments, "Not a big biker, are you?" Rob retches a few more times and then prepares to shoot his arrows. Rob hits the bull's-eye on his first shot, and everyone congratulates him. Anderson says that they won't find out until later whether they won any money or not. In an interview, Rob says that he may have aroused some suspicions, "but, eh, whatever works."
Anderson explains the second section: the Pulse Rope Walk. Heather, Lisa, Myra, and Al have to walk across a rope, which is stretched between two trees. While crossing, if anyone's heart rate goes above one hundred thirty beats per minute, the person has to stop and stand still until his or her heart rate goes below the mark again. The first three players get to cross the lower rope. The last player has to cross the lower rope and then also cross the higher rope. All of the crossings have to take place within one hour. The contestants discuss in what order they should cross the ropes. Lisa suggests that Myra go last, since she's a pilot and might be used to heights. Myra demurs, claiming that she just got over a cold. Al volunteers to go last, joking that whatever he does, his heart rate's up. Lisa asks whether he's sure. Al says that he's not scared of heights, but that he is nervous.
Heather heads up to the ropes first. Bill voice-overs that they tried to pick the women they thought would be calmest. Heather starts across the rope, and her heart rate barely moves above seventy. Al thinks that Heather is "as cool as the other side of the pillow." Bill comments that Heather's current heart rate is lower than his resting rate. Heather finishes her crossing quickly, and descends while the others applaud.
