The Amazing Race is an American reality competition show in which teams of two race around the world. Each season is split into legs, with each leg requiring teams to deduce clues, navigate themselves in foreign areas, interact with locals, perform physical and mental challenges, and travel by airplane, boat, taxi, and other public transportation options on a limited budget provided by the show. Teams are progressively eliminated at the end of most legs, while the first team to arrive at the end of the final leg wins the grand prize of US$1 million. As the original version of the Amazing Race franchise, the CBS program has been running since September 5, 2001. Numerous international versions have been developed following the same core structure, while the American version is also broadcast to several other countries.
