Wife carrying is another sport with minimal equipment requirements — all you need is a wife ... to carry. The racers heft their significant others on their backs and fight to be the first to complete a race course filled with obstacles and impediments. The sport of wife carrying was introduced in Finland and has since spread all over the world. It is overseen by the International Wife Carrying Competition Rules Committee, which sets the official guidelines for all races. The winner of the world championships held in Sonkajärvi, Finland, win the weight of his wife in beer.
