The Amazing Race (TAR) is a popular reality TV show. Elise Doganieri and Bertram van Munster created it in 2001 and since then it has won many awards. In the show, teams travel around the world to different places. They try to arrive first, or at least not come last and they also try to win prizes on their journey. Every year, between 10 and 12 teams play on the show. There are two people in each team and they must know each other before they come on the game. For example, they can be husband and wife, parents and children, friends, etc. They have to travel to different countries and work together on the journey. The teams get some money at the beginning of the race and they use it to buy food, tickets, etc. They can use planes, trains, bikes or even skis to travel. The teams explore places they've never been to before and have games or ‘challenges’. These challenges have some connection to the country they are in and can be things like riding a camel, solving puzzles or eating a lot of food, for example. The teams often have to face extreme weather conditions during their journey. Many times they are outside in the rain or snow or in storms and get cold and wet. It's all part of the experience, though. Each week, one team leaves the show, and in the end there are only four teams. The first team to get to the last city on the journey wins the game. TAR is a very hard game and the teams become really stressed, but it's an amazing experience.
