TOKYO -- It was inevitable that one of the most durable records in sports, Bob Beamon's long jump of 29 feet, 2 1/2 inches in the 1968 Olympic Games at Mexico City, eventually would be broken. It was even predictable, considering the favorable conditions at the National Stadium, that it would happen here in track and field's World Championships.
But the assumption by the sport's followers for almost a decade was that when the record finally fell, it would be at the fleet feet of the most consistently excellent performer in the event's history, two-time Olympic and world champion Carl Lewis.
Instead, the long jump's first new world-record holder in 23 years is Mike Powell, 27, of Rancho Cucamonga, Calif., whose most significant title other than the one he won in the 1990 National Championships was as a sporting goods chain's celebrity dunk champion.
"I was 4 years old when [Beamon] got that record, but it feels great to break it because everyone's been saying that Carl will be the one to do it," Powell said. "Nobody gave me credit. Not to say, 'In your face,' but . . . In your face."
Powell broke track and field's oldest record decisively last night, landing at 29-4 1/2 after he lifted off in the fifth of six rounds during the long jump final. His record came before a near-capacity crowd in the 62,000-seat stadium on a night of ominous storm clouds, stifling humidity and gusting winds.
Those apparently are ideal atmospheric conditions for long jumping. Not only were they similar to those in Mexico City when Beamon made his historic jump, breaking the previous record by 1-9 3/4 , but five of the top seven performances of all time were recorded in this competition.
Four were by Lewis, 30, of Houston, who also surpassed Beamon's mark with a fourth-round jump of 29-2 3/4 , although it would not have counted as a world record because the tail wind of 2.9 meters per second at the time was more than the 2.0 allowable for record consideration.
In putting together the best series ever, Lewis also had jumps of 29-1 1/4 , 29-0 and 28-5 3/4 when the wind was 2.0 mps or less, plus another wind-assisted jump of 28-11 3/4 . Before last night, only two men, Beamon in 1968 and the Soviet Union's Robert Emmiyan in 1987, had jumped farther than 29 feet.
Each did it once and at an altitude above 1,000 feet, which, because of the thin air, is considered beneficial to long jumpers. Tokyo is at sea level, adding to the luster of the performances by Powell and Lewis.
Larry Myricks, 35, finished third with a best jump of 27-7 1/2 , as he and his United States teammates duplicated their sweep of the medals in the 1988 Olympics at Seoul, South Korea. The difference was that Lewis had to settle for silver this time, perhaps an even more astonishing development than the world record, considering that he arrived in Tokyo with a 10-year, 65-meet winning streak.
There was no indication that it would end here. He apparently was in peak condition, having broken the world record in the 100-meter -- Sunday with a time of 9.86 seconds. Thursday, he was the leading qualifier among the 12 long jump finalists with a leap of 28-1 and had fouled on another effort that appeared close to eclipsing Beamon's record.
Seemingly stunned by the defeat, Lewis said yesterday: "I had the greatest series of all time. He had just one jump. He may never do it again, but he did it tonight. That's the long jump. It's not a series. It's a jump."
Powell's record-breaking jump was almost a foot farther than his personal best of 28-5. He established that in 1990, when he won the national championship and was ranked No. 1 in the world in a year during which Lewis competed in the event only twice, beating Powell both times.
Although he had lost in the 15 other times that they had met since 1983, one area where Powell has never fallen short of Lewis is in confidence. Even in 1986, when Powell was a relatively unknown senior at UCLA after transferring from UC Irvine, Bob Kersee, the Bruins women's coach, said Powell talked about beating Lewis.
"Everybody kidded him that he was too dumb to know he couldn't beat Carl Lewis," Kersee said.
It still had not sunk in this week.
"After he ran that 9.86 in the 100, I knew he would be ready to jump far," Powell said. "I didn't get upset. I just knew I'd have to jump farther."
Powell said he was so eager to start the competition, particularly after the U.S. triple jumpers who performed earlier in the week told him about the extraordinarily fast runway, that he almost hyperventilated before his first jump, a mere 25-9 1/4 .
"I was so pumped up, so motivated, that I couldn't breathe," he said. "At that point, I said: 'OK, just relax. You don't have to be crazy and all psyched up. Just relax and let your body do what it will do.' "
