From 1912 to 1980 the Olympic Modern Pentathlon competition was held over five days with one event per day.
Between 1984 and 1992, the competition was held over four days with either running and shooting or swimming and shooting on the same day.
For the Atlanta Olympic Games in 1996, the competition was a one-day event in which 32 men who qualified via pre-Olympic competitions participated.
In 1998, the UIPM received approval for women to compete in the Sydney 2000 Olympics Games and so 24 men and 24 women competed in individual competition and for the first time in history, the Pentathlon venues were 96% sold out.
UIPM subsequently received an increase in the quota and in Athens 2004, 32 men and 32 women competed and both competitions were 100% sold out.
Following this success, UIPM received in February 2006 a further increase in quota from the IOC Executive Board – in Beijing 2008 Olympic Games, 36 men and 36 Women took part in the Olympic Modern Pentathlon event.
Following the Paris 2024 Olympic Games, the UIPM replaced equestrian (show jumping) with Obstacle racking at all levels, which will debut at the Los Angeles Olympic Games in 2028.
