The modern Summer Olympic Games have been held every four years since the first Games in 1896 and Olympic records are recognised by the International Olympic Committee (IOC) in each event. The athletics events, which take place at each Games, are divided into four groups: track events (including sprints, middle- and long-distance running, hurdling and relays), field events (including javelin, discus, hammer, pole vault, long and triple jumps), road events (such as walks and the marathon) and combined events (the heptathlon and the decathlon).〔 Women compete in 23 athletics events during the Games, and men compete in 24; while 21 of the events are the same for both men and women, men exclusively compete in the 50 km walk, the women's combined event is the heptathlon while the men compete in the decathlon, and the short distance hurdles for women is contested over 100 m, ten metres shorter than the men's event. Some Olympic records have been broken but later rescinded by the IOC. In 1988, Canadian sprinter Ben Johnson broke the Olympic and World record in the 100 metres sprint, but was subsequently disqualified after it was discovered that he had used anabolic steroids to enhance his performance. His record was expunged and the gold medal was instead awarded to American Carl Lewis. Hungarian athlete Róbert Fazekas broke the Olympic record in the men's discus in 2004 but was later stripped of both his gold medal and the record after it was deemed that he had "committed an anti-doping rule violation". The longest standing modern Olympic athletics record is Bob Beamon's achievement in the men's long jump at the 1968 Summer Olympics.〔 The jump, at , also broke the existing world record by , and stood as the world record for 23 years until Beamon's compatriot, Mike Powell, jumped farther in the 1991 World Championships in Athletics in Tokyo. During the 2012 Games, six men's and five women's records were broken. Note, only those events currently competed for and recognised by the IOC as Summer Olympic events are listed. ==Men's records== ''♦ denotes a performance that is also a current world record.
