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.
