At the 1968 Summer Olympics Bob Beamon jumped 8.90 m (29 ft 2 1â4 in) at an altitude of 7,349 feet (2,240 m), a jump not exceeded for 23 years, and which remains the second longest legal jump of all time.
This jump remains the longest ever not to win an Olympic or World Championship gold medal, or any competition in general. The current world record for women is held by Galina Chistyakova of the former Soviet Union who leapt 7.52 m (24 ft 8 in) in Leningrad on June 11, 1988, a mark that has stood for 27 years.
