The International Olympic Committee is the international, non-governmental, sports governing body of the modern Olympic Games. Founded in 1894 by Pierre de Coubertin and Demetrios Vikelas, it is based in Lausanne, Switzerland. The IOC is the authority responsible for organizing the Summer, Winter, and Youth Olympics. The IOC also is the governing body of the National Olympic Committees (NOCs) and of the worldwide Olympic Movement, the IOC's term for all entities and individuals involved in the Olympic Games. As of 2020, 206 NOCs officially were recognized by the IOC. The IOC president has been Thomas Bach since 2013.
The modern Olympic Games are the world's leading international sporting events. They feature summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games are considered the world's foremost sports competition, with more than 200 teams, representing sovereign states and territories, participating. By default, the Games generally substitute for any world championships during the year in which they take place. The Olympic Games are held every four years. Since 1994, they have alternated between the Summer and Winter Olympics every two years during the four-year Olympiad.
The Summer Olympic Games, also known as the Games of the Olympiad, is a major international multi-sport event normally held once every four years. The inaugural Games took place in 1896 in Athens, Greece, and the most recent was held in 2024 in Paris, France. This was the first international multi-sport event of its kind, organized by the International Olympic Committee (IOC) founded by Pierre de Coubertin. The tradition of awarding medals began in 1904; in each Olympic event, gold medals are awarded for first place, silver medals for second place, and bronze medals for third place. The Winter Olympic Games were created out of the success of the Summer Olympic Games, which are regarded as the largest and most prestigious multi-sport international event in the world.
The Winter Olympic Games is a major international multi-sport event held once every four years for sports practiced on snow and ice. The first Winter Olympic Games, the 1924 Winter Olympics, were held in Chamonix, France. The modern Olympic Games were inspired by the ancient Olympic Games, which were held in Olympia, Greece, from 776 BCE to 394 CE. The Baron Pierre de Coubertin of France founded the International Olympic Committee (IOC) 1,500 years later in 1894, leading to the first modern Summer Olympic Games in Athens, Greece in 1896. The IOC is the governing body of the Olympic Movement, with the Olympic Charter defining its structure and authority. The original five Winter Olympic Sports were bobsleigh, curling, ice hockey, Nordic skiing, and skating. The Games were held every four years from 1924 to 1936, interrupted in 1940 and 1944 by World War II, and resumed in 1948. Until 1992, the Summer Olympic Games and the Winter Olympic Games were held in the same year. A decision to change this was made in 1986, when during the 91st International Olympic Committee session, IOC members decided to alternate the Summer Olympic Games and the Winter Olympic Games on separate four-year cycles in even-numbered years. Also, at that same congress it was decided that 1992 Winter Olympics would be the last to be held in the same year as the Summer Games and that to change the rotation, the games that would be held in 1996 would be brought forward by two years, being scheduled to 1994. After those games, the next were to be held in 1998 when the four-year Olympic Cycle resumed.
The 2000 Summer Olympics, officially the Games of the XXVII Olympiad, officially branded as Sydney 2000, and also known as the Games of the New Millennium, were an international multi-sport event held from 15 September to 1 October 2000 in Sydney, New South Wales, Australia. It marked the second time the Summer Olympics were held in Australia, and in the Southern Hemisphere, the first being in Melbourne, in 1956.
The 1996 Summer Olympics were an international multi-sport event held from July 19 to August 4, 1996, in Atlanta, Georgia, United States. These were the fourth Summer Olympics to be hosted by the United States, making it the first country to have three different cities host the Summer Olympics. It also marked the 100th anniversary of the 1896 Summer Olympics in Athens, the inaugural edition of the modern Olympic Games. These were also the first Summer Olympics to be held in a different year than the Winter Olympics since the Winter Olympics commenced in 1924, as part of a new IOC practice implemented in 1994 to hold the Summer and Winter Games in alternating, even-numbered years. The 1996 Games were the first of the two consecutive Summer Olympics to be held in a predominantly English-speaking country, preceding the 2000 Summer Olympics in Sydney, Australia. These were also the last Summer Olympics to be held in North America until 2028, when Los Angeles will host the games for the third time.
The 2004 Summer Olympics, officially the Games of the XXVIII Olympiad and officially branded as Athens 2004, were an international multi-sport event held from 13 to 29 August 2004 in Athens, Greece. The Games saw 10,625 athletes compete, some 600 more than expected, accompanied by 5,501 team officials from 201 countries, with 301 medal events in 28 different sports. The 2004 Games marked the first time since the 1996 Summer Olympics that all countries with a National Olympic Committee were in attendance, and also marked the first time Athens hosted the Games since their first modern incarnation in 1896 as well as the return of the Olympic games to its birthplace. Athens became one of only four cities at the time to have hosted the Summer Olympic Games on two occasions. A new medal obverse was introduced at these Games, replacing the design by Giuseppe Cassioli that had been used since 1928. The new design features the Panathenaic Stadium in Athens rectifying the long-running mistake of using a depiction of the Roman Colosseum rather than a Greek venue.
The 2008 Summer Olympics, officially the Games of the XXIX Olympiad and officially branded as Beijing 2008, were an international multisport event held from 8 to 24 August 2008, in Beijing, China. A total of 10,942 athletes from 204 National Olympic Committees (NOCs) competed in 28 sports and 302 events, one event more than those scheduled for the 2004 Summer Olympics. This was the first time China had hosted the Olympic Games, and the third time the Summer Olympic Games had been held in East Asia, following the 1964 Olympics in Tokyo, Japan, and the 1988 Olympics in Seoul, South Korea. These were also the second Summer Olympic Games to be held in a communist state, the first being the 1980 Summer Olympics in the Soviet Union.
The 1992 Summer Olympics, officially the Games of the XXV Olympiad and officially branded as Barcelona '92, were an international multi-sport event held from 25 July to 9 August 1992 in Barcelona, Catalonia, Spain. Beginning in 1994, the International Olympic Committee decided to hold the Summer and Winter Olympics in alternating even-numbered years. The 1992 Summer and Winter Olympics were the last games to be staged in the same year. These games were the second and last two consecutive Olympic games to be held in Western Europe after the 1992 Winter Olympics in Albertville, France, held five months earlier.
The 1984 Summer Olympics were an international multi-sport event held from July 28 to August 12, 1984, in Los Angeles, California, United States. It marked the second time that Los Angeles had hosted the Games, the first being in 1932. This was the first of two consecutive Olympic Games to be held in North America with Calgary, Alberta, Canada to host the 1988 Winter Olympics. California was the home state of the incumbent U.S. President Ronald Reagan, who officially opened the Games. These were the first Summer Olympic Games under the IOC presidency of Juan Antonio Samaranch.
The 1980 Summer Olympics, officially known as the Games of the XXII Olympiad and officially branded as Moscow 1980, were an international multi-sport event held from 19 July to 3 August 1980 in Moscow, Soviet Union, in present-day Russia. The games were the first to be staged in an Eastern Bloc country, as well as the first Olympic Games and only Summer Olympics to be held in a Slavic language-speaking country. They were also the only Summer Olympic Games to be held in a socialist country until the 2008 Summer Olympics held in China. These were the final Olympic Games under the IOC Presidency of Michael Morris, 3rd Baron Killanin before he was succeeded by Juan Antonio Samaranch shortly afterwards.
The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440-yard dash (402.336 m)—which is a quarter of a mile and was referred to as the "quarter-mile"—instead of the 400 m (437.445 yards), though this distance is now obsolete.
The 2016 Summer Olympics, officially the Games of the XXXI Olympiad and officially branded as Rio 2016, were an international multi-sport event held from 5 to 21 August 2016 in Rio de Janeiro, Brazil, with preliminary events in some sports beginning on 3 August. Rio de Janeiro was announced as the host city at the 121st IOC Session in Copenhagen, Denmark, on 2 October 2009.

The all-time medal table for all Olympic Games from 1896 to 2024, including Summer Olympic Games, Winter Olympic Games, and a combined total of both, is tabulated below. These Olympic medal counts do not include the 1906 Intercalated Games which are no longer recognized by the International Olympic Committee (IOC) as official Games. The IOC itself does not publish all-time tables, and publishes unofficial tables only per single Games. This table was thus compiled by adding up single entries from the IOC database.
The steeplechase is an obstacle race in athletics which derives its name from the steeplechase in horse racing. The foremost version of the event is the 3000 metres steeplechase. The 2000 metres steeplechase is the next most common distance. In youth athletics, a distance of 1000 metres is occasionally used for steeplechase races.
