Medley Swimming is a combination of four different swimming styles—backstroke, breaststroke, butterfly, and freestyle—into one race. This race is either swum by one swimmer as individual medley (IM) or by four swimmers as a medley relay.
Freestyle is a category of swimming competition, defined by the rules of the International Swimming Federation (FINA), in which competitors are subject to only a few limited restrictions on their swimming stroke. Freestyle races are the most common of all swimming competitions, with distances beginning with 50 meters and reaching 1,500 meters, also known as the mile. The term 'freestyle stroke' is sometimes used as a synonym for 'front crawl', as front crawl is the fastest surface swimming stroke. It is now the most common stroke used in freestyle competitions.
