The teams take off from their Pit Stop at a rice paddy and receive a clue instructing them to travel by taxi twenty miles to the Ly Thai To Garden in Hanoi, Vietnam. The teams receive 588,000 Vietnamese dong, but must first pick it up, as it is not included with the clue. At the Garden, the teams receive an auditory clue that eventually directs them to the Hydrofoil Harbor in Ben Xe Bai Chay. There, the teams face a Roadblock which requires one member of each team to make a steep climb. After completing the task, the teams take a motorboat 1.2 miles to the Song Sot Cave and search for the next clue. It's a Detour that requires them to choose between Over (delivering supplies) or Under (hauling oysters.) Difficulty in navigating the boats and problems with wind lead to a suspenseful finish.

The Amazing Race is an adventure reality show hosted by Phil Keoghan that pits 10, 11, or 12 teams of 2 or 4 people against each other in a race around the world for approximately 40 days. In a leg, they go to destinations where they will complete a roadblock, a task where 1 person completes (Season 1-7) or 2 people (Season 8), a detour, where you have to decide between two tasks that are usually opposite of each other, and a miscellaneous task.
After they complete all these tasks, they will be directed to go to a Pit stop where they will have a 24 hour rest period where they will be able to eat, drink, sleep, and mingle with other teams. The last team to check into the Pit Stop usually is eliminated, but sometimes there is a non-elimination leg in which no one is eliminated. After all teams are eliminated except for 3, these three race to the finish line where the winning team wins 1 million dollars.
