Sergey Bubka started competing on the international athletics scene in 1981 when he participated in the European Junior Championship finishing seventh. But the 1983 World Championship held in Helsinki was his actual entry point to the world athletics, where a relatively unknown Bubka snatched the gold, clearing 5.70 metres (18 feet 8 inches). The years that followed witnessed the unparalleled dominance of Bubka, with him setting new records and standards in pole vaulting.

Bubka won the pole vault event in six consecutive IAAF World Championships in Athletics in the period from 1983 to 1997:

Bubka broke the world record for men's pole vault 35 times during his career. He broke the outdoor world record 17 times and the indoor world record 18 times. Bubka lost his outdoor world record only once in his illustrious career. After Thierry Vigneron, of France, broke his record on 31 August 1984 at the Golden Gala international track meet in Rome, Bubka subsequently reclaimed the record on his next run, just minutes later.

He became the first athlete ever to jump over 6.10 metres, in San Sebastián, Spain in 1991. Until January 2014, no other athlete on earth had cleared 6.07, indoors or outdoors. In 1994, he achieved his personal record with a vault of 6.14 meters, long after many commentators assumed the great sportsman was retired. Bubka increased the world record by 21 centimetres (8 inches) in the period from 1984 to 1988, more than other pole vaulters had achieved in the previous 12 years. He cleared 6.00 meters or better on 45 occasions. As of June 2015, 6 meters had been cleared by all athletes worldwide exactly 100 times.

He held the indoor world record of 6.15 meters, set on 21 February 1993 in Donetsk, Ukraine for almost 21 years until France's Renaud Lavillenie cleared 6.16 metres on 15 February 2014 at the same meet in the same arena. He is the current outdoor world record holder at 6.14 meters, a record he has held since 31 July 1994, though since adopting rule 260.18a in 2000 the IAAF regards Lavillenie's record as the official "world record."

Bubka has been involved with the International Association of Athletics Federations (IAAF) since 2001 and has served as a Vice President since 2007. During this time, he remained on the Athletes’ Commission (2001–2011) and is also a Council Member for ASOIF, the Association for Summer Olympic International Federations. Bubka commented: “I have been working at the IAAF for a long time and my work is not limited to one area. The good of athletics is something deep in my heart.” Bubka has been IAAF Council Member (2001-), IAAF Senior Vice-President (2007–2011), Vice-President (2011-), IAAF Development Commission Deputy Chairman (2007–2011), then Chairman (2011-), IAAF Athletes Commission member (2001–2011) and IAAF Competition Commission member (2003-). He was also a Coordination Commission Chairman of IAAF World Championships in Daegu 2011 and Moscow 2013.

As President of the National Olympic Committee in Ukraine since 2005, he has transformed the organisation into one of the most progressive in the world. It has staff based in all of the nation’s 27 regions with each taking responsibility for delivering an array of programmes designed to bring youngsters into sport, realise the potential of the most able and promote the Olympic Movement and its values. A National Olympic Day, the Olympic Stork which provides Olympic-themed education to more than 250,000 school classes across the country, televised annual awards and an Olympic Academy have all been established under Bubka’s reign. “NOCs must do more than select and send teams to Olympic Games,” says Bubka. “They are at the forefront of efforts to educate young people and help them become involved in sport and adopt a healthy lifestyle. To do that we need to work together globally because if we don’t we risk losing the younger generation.”

Bubka is Senior Vice President of the International Association of Athletics Federations (IAAF), serving since 2007, and President of the National Olympic Committee of Ukraine, serving since 2005. He is also an Honorary Member of the International Olympic Committee (IOC), having been involved since 1996.

Sergey Bubka first got involved with the International Olympic Committee (IOC) in 1996 when he was elected as a Member of the Athletes’ Commission, providing input into the governance of sport from the perspective of an active athlete. Almost 20 years later he is still involved as an Honorary Member. “I knew that I wanted to be involved in running sport and, in particular to be involved in the Olympic Movement,” he said. He became an IOC Member in 1999 and has been involved in a wide range of Commissions, including Chairman of the Evaluation and then the Coordination Commissions for the inaugural Youth Olympic Games in Singapore in 2010. On 28 May 2013 Sergey Bubka announced that he would run for President of the International Olympic Committee. At the 125th IOC Session in Buenos Aires he lost the vote to Thomas Bach.

Today Bubka is a member of the ‘Champions for Peace’ club, a group of more than 90 famous elite created by Peace and Sport, a Monaco-based international organization placed under the High Patronage of H.S.H Prince Albert II. This group of top level champions, wish to make sport a tool for dialogue and social cohesion. http://www.peace-sport.org/our-champions-of-peace/
