Bob Beamon set the Olympic men’s long-jump record with 8.90 metres at Mexico City 1968.
Beamon produced the leap on 18 October 1968 during the Olympic final. His jump improved the previous world record by 55 centimetres, an extraordinary margin in an event usually decided by much smaller differences. The altitude of Mexico City, about 2,240 metres above sea level, helped reduce air resistance, while the runway’s tailwind was within the legal limit.
The distance remained the world record until 1991, when Mike Powell jumped 8.95 metres at the World Championships in Tokyo. Beamon’s 8.90 metres remains the Olympic record. Carl Lewis won the 1984, 1988, 1992 and 1996 Olympic long-jump titles, but he did not hold the Olympic record.
Beamon struggled to reproduce the same distance consistently after Mexico City, yet his performance became one of the defining moments of twentieth-century athletics. The official measurement was converted from 29 feet 2½ inches, the imperial result displayed at the time.
