On October 18, 1968, Bob Beamon took one run-up in the long jump final at the Olympic Stadium in Mexico City and landed at 8.90 metres, breaking the world record by fifty-five centimetres in a single attempt. The previous mark stood at 8.35 metres, shared between Ralph Boston and Igor Ter-Ovanesyan, and the jump was so far beyond it that the optical measuring equipment set up for the Games could not register where he had touched down. The tape came out. Beamon had gone 29 feet 2½ inches, and nobody had reached 28 feet before.
Mexico City sits at about 2,240 metres, and the thin air was the explanation most people reached for at the time. It was worth perhaps eight inches of the gain by later calculation, and the rest came from a run-up near thirty miles an hour and a take-off that barely checked. Beamon had fouled twice in the qualifying round and had one legal attempt left when he made the jump. He did not jump again. He sank down in the pit and could not get up for several minutes.
Sports writers called it the leap into the twenty-first century. The record lasted. It stood for twenty-three years, which is longer than any other mark in the event's modern history has survived, and it ended only when Mike Powell went 8.95 metres at the World Championships in Tokyo in 1991, in a final where Carl Lewis also jumped beyond the old figure. Beamon's jump is still the Olympic record.
Beamon had grown up in Jamaica, Queens, in New York, and had been sent to a school for difficult boys after losing both parents, where he took up the long jump almost by accident. He never went near 8.90 metres again. A hamstring injury in 1969 finished him as a serious contender while he was still in his early twenties, and he spent the following decades coaching, working in sports administration and, for a time, in a savings and loan office.
