, sometimes referred to as TAR, is a reality television game show in which teams of two people (with one exception), who have some form of a preexisting personal relationship, race around the world in competition with other teams. Contestants strive to arrive first at "pit stops" at the end of each leg of the race to win prizes and avoid coming in last, which carries the possibility of elimination or a significant disadvantage in the following leg. Contestants travel to and within multiple countries in a variety of transportation modes, including planes, taxis, rental cars, trains, buses and boats. The clues in each leg point the teams to the next destination or direct them to perform a task, either together or by a single member. These challenges are related in some manner to the country or culture where they are located. Teams are progressively eliminated until three teams are left; at that point, the team that arrives first in the final leg is awarded a large cash grand prize, usually one million U.S. dollars.
Created by Elise Doganieri and Bertram van Munster, the original series has aired in the United States since 2001 and has earned seven Primetime Emmy Awards, including all six "Outstanding Reality-Competition Program" awards that have been given. Emmy-award-winning New Zealand television personality Phil Keoghan has been the popular host of the show since its inception. Hollywood mega-producer Jerry Bruckheimer has been TAR's main producer. The show has branched out to include a number of international versions following a similar format.
