The Wife-carrying World Championship has been celebrated in a small town in central Finland since 1992. In 1992, the people of the town decided to restart some long-forgotten traditions. Back in the late 1800s, there was a robber called Rosvo-Ronkainen in that area. He was said to only accept men as members of his gang who proved their worth in challenges. At that time, it was also a common practice to steal women from neighboring villages. This event is becoming increasingly popular. A large number of competitors, people, and journalists from Finland to Canada attend the Wife-carrying World Championship every year. The event is famous for its warm and humorous atmosphere. The Wife-carrying World Championship is held on a 253.3 meters long official track. The track has two dry obstacles  and a water obstacle, about a meter deep. There are a few basic rules and the winner is the couple who complete the course in the shortest time. The wife to be carried may be your own, or your neighbor's. The minimum weight of the wife to be carried is 49 kg. If she is less than 49kg, the wife will be given a heavy bag to carry. Each time a competitor drops his wife, that couple will be fined 15 seconds. Alongside with the Wife-carrying World Championship, there is also a team competition. The distance is the same but three men in the team carry the wife in turns. At the exchange point the carrier has to drink official "wife-carrying drink". Then he may continue the race. A special prize is awarded to the team with the best costumes.
