Modern pentathlon is a multi-discipline sport that was specially created for inclusion in the 1912 Olympic Games. It is based on the pentathlon event of the Ancient Olympics. The five disciplines are fencing, freestyle swimming, show jumping, pistol shooting and cross-country running. The last two are combined in a similar way to the winter sport of biathlon which comprises rifle shooting and cross-country skiing. The sport's world governing body is the Union Internationale de Pentathlon Moderne (UIPM), which is based in Monte Carlo and has 115 member countries.
