Marcus’ team became the first to finish the task. Molly's team was soon joined by Abby-Will, Luis-Michelle and Quinton-Mattie on the site. The third and final group included Derek-Claire, Glenda-Lumumba, Linton-Sharik and David- Aubrey.The teams clearing the tasks went to Petra, where they were a choice between a detour task: feeding some camels or finishing a puzzle. Marcus and Michael chose the camel-related task. Linton and Sharik were the last team to reach the site of the first task and also chose the camel feeding detour, which involved heavy physical labor.Luis-Michelle won the leg and $5000. Derek-Claire came second and Michael-Marcus came third. Abby-Will were fourth, followed by Molly-Emily.Quinton-Mattie surprisingly came sixth and Glenda-Lumumba came seventh.
