Wikipedia
The modern pentathlon is an Olympic sport that comprises five different events: fencing, 200m freestyle swimming, show jumping, and a final combined event of pistol shooting and a 3200m cross-country run. The sport has been a core sport of the Olympic Games since 1912 despite dispute. An annual World Championship event has been held since 1949.
Originally the competition took place over four or five days; in 1996 a one-day format was adopted in an effort to be more audience-friendly. Modern pentathlon, despite its long Olympic history, has had to justify its inclusion in the modern Olympic Games several times. On February 11, 2013 in Lausanne, the IOC confirmed modern pentathlon once again as one of the 25 core sports of the Olympic program through to 2020. The governing body, Union Internationale de Pentathlon Moderne (UIPM), administers the international sport in more than 90 countries in all the continents of the world.
