Modern pentathlon has been the subject of numerous changes since its creation.
Fencing In 2015 — and for the first time in the 2016 Summer Olympics — a system of an additional bonus round was added to épée fencing in international competitions. Before that, there was only the round-robin format. From 2025, after a round-robin system in the qualification stage, the finals feature a direct elimination stage where pairings are based on round-robin results. The bonus round was eliminated.
Swimming Until the 2000 Olympics, the distance for swimming was 300 metres; at that time it was changed to 200 metres. In 2026, the distance was further reduced to 100 metres.
Riding The distance of the cross-country riding event was reduced from 5 km to 4 km in 1972. For the
1988 Summer Olympics cross-country riding was changed to show jumping. This event was replaced by an obstacle course event after the 2024 Olympics, and horse riding is no longer part of Modern Pentathlon.
Shooting and running From 1912 to 1988
regular pistols or later
sport pistols were used for shooting. From 1989 until 2009, the shooting discipline involved firing a 4.5 mm (
.177 cal)
air pistol in the standing position from 10 metres distance at a stationary target. The format was that of the
10 metre air pistol competition: each competitor had 20 shots, with 40 seconds allowed for each shot. Beginning with the World Cup events in 2011, in a move designed to improve the safety and sustainability of the sport,
laser pistols were used instead of pistols with actual projectiles. At the same time, unlimited shots were allowed for each timed shooting round. There is a slight delay between the trigger pull and the laser firing, simulating the time it would take for a pellet to clear the muzzle. Air pistols with laser transmitters were introduced during the transitional period and are still in use. Purpose-built laser pistols are developed and commonly used since the middle of the 2010s. Laser pistols and targets have to be
certified by the UIPM. The standard target dimension is a 250 mm diameter circle, with a target valid zone of 59.5 mm. In 2008, the
UIPM Congress passed a motion to combine the shoot and run disciplines. This is now known as the “combined event” and is the final event of the competition. In 2009, the combined event consisted of three 1000 m laps, each preceded by laser shooting at five targets in 70 seconds or less. From the start of the 2013 season, the laser-run (term coined in 2016) was changed to consist of four 800 m laps (increasing the distance to 3.2 kilometres) each preceded by laser shooting at five targets in 50 seconds or less. This change was intended to restore some of the importance of the shooting skill felt to have been lost in the original 2009 combined event. After the 2020 Summer Olympics (postponed to 2021), the run was further modified to a new model of five 600 m laps. The laser run is organized as a
pursuit race: athletes start with a handicap based on the summed points gathered in the previous disciplines; as such it determines the overall outcome of the modern pentathlon event. The rest of the field face a one-second handicap for each pentathlon point by which they trail the leader.
The New York Times asked whether the name ought to be changed to "tetrathlon" given that two of the five disciplines had been combined into a single event. It is the summer equivalent of the
biathlon winter sport, which involves skiing and shooting.
Overall scoring and operation Scoring was originally done by a points-for-place system with the lowest score winning. Since the 1954 World Cup points tables are used for each of the five events and points are added for the final score. This scoring was first used in the
1956 Summer Olympics.
Replacement of riding with obstacle course racing The riding discipline attracted criticism during the
2020 Summer Olympics after multiple athletes in the
women's event struggled to control their randomly-assigned horses. This culminated in the German team's coach,
Kim Raisner, being removed from the event after striking a horse with her fist. Following the Games, in November 2021 it was reported that the UIPM was opening consultations on the proposed replacement of riding with another discipline. The decision was ratified during the UIPM's Congress on 27 November 2021, with the changes intended to be implemented for the
2028 Summer Olympics. According to critics of the decision, the UIPM voted for the change without consulting athletes, claiming
force majeure. The decision was met with criticism from various athletes and bodies, who considered riding to be integral to modern pentathlon. Some also accused the UIPM of hindering debate in favor of riding during the congress. A group known as "Pentathlon United" called for the IOC to investigate the UIPM's governance, and proposed a plan to maintain riding with rule changes to bring them in line with those of the
International Federation for Equestrian Sports (FEI), and a focus on
animal welfare. In May 2022, the UIPM announced it would hold an
obstacle racing test event alongside the 2022 Modern Pentathlon World Cup final in
Ankara, citing that it had received the most support out of the over 60 disciplines proposed, was more cost-effective, would help make the event more attractive to a younger audience, and was "compatible with the DNA of modern pentathlon". The competition course was developed with input from
World Obstacle and Japanese broadcaster
TBS (producer of the sports competition series
Sasuke, whose
format has been widely exported under the title
Ninja Warrior), and the event featured a mix of athletes from both the obstacle racing and modern pentathlon communities. Australian gymnast
Olivia Vivian—a grand finalist of
Australian Ninja Warrior—won the gold in the women's competition. On 9 July 2022, Pentathlon United shared a survey of 213 responses from 40 countries, claiming that 68.5% of the respondents were current athletes, that indicated more than 92% of current modern pentathlon participants wanted to preserve the equestrian discipline as part of the sport. The group stated, "A total of 74.18% chose the reformed version of equestrian, which puts horse welfare among the central themes, while concern over the cost and accessibility of the equestrian discipline is also acknowledged in the 16-point plan." Of those polled, Pentathlon United claimed that only athletes from the
United Kingdom showed any support for an obstacle race, with athletes from the
United States overwhelmingly voting for a reformed version of
equestrian sport. In October 2022, modern pentathlon's elected Athletes Committee launched a campaign entitled #OurFuture, highlighting the views of pentathletes in favour of the change. Athletes such as Olympic silver medallists Elodie Clouvel (France) and Ahmed Elgendy (Egypt) supported the transition when participating in a media conference at UIPM Headquarters in Monaco. They were joined by Athletes Committee representatives including the group's Chair, Yasser Hefny OLY (Egypt), Jamie Cooke (Great Britain) and Natalya Coyle OLY (Ireland), as well as former Pan American champion Tamara Vega (Mexico). In November 2022, the UIPM Congress voted 69–11 in favor of replacing riding with obstacle course racing; an associated motion established that the changes would take effect for junior competition in 2023. The 2023 and 2024 junior world championships duly took place with obstacle in place of equestrian. The new format's implementation at the senior level will be formalised after the
2024 Summer Olympics. On 22 June 2023, the UIPM shared a poll of 1,500 Americans by
YouGov that they commissioned in support of their decision to replace riding with obstacle course racing, citing that the survey showed that "45% of Gen Z and 41% of Millennials more likely to watch the Olympics on television if it featured a
ninja-style obstacle race...taken as a percentage of the U.S. population, this would equate to nearly 45 million more people watching the Games". The UIPM also stated, "More than two-thirds (37%) of survey respondents said they would be more likely to watch the new-look Modern Pentathlon at the Olympic Games, and 46% of those cited enjoying ninja-style obstacle races as the reason, with 34% describing the reason for their answer: 'I think the Modern Pentathlon needs to embrace change'." The article also indirectly referenced the popular TV show
American Ninja Warrior. Іn August 2023 during the 2023 UIPM Pentathlon and Laser Run World Championships, the UIPM signed a
memorandum of understanding with World Obstacle to collaborate on the integration of obstacle racing into the modern pentathlon at the senior level; UIPM president Klaus Schormann stated that the federation was "want[ing] to bring a different challenge to the Olympic Movement, to be more urban and provide something that young generations will love." The MoU was criticised by Pentathlon United, who questioned World Obstacle's finances (in particular, being funded solely by one person with no other commercial revenue). == Popularity ==
