Usain Bolt Shatters 100-Meter World Record

Bolt pushed himself from start to finish on Sunday night, and the result was a stunning time of 9.58 seconds in the men’s 100-meter final at the track and field world championship here. His time was eleven/hundredths of a second better than his already ethereal world-record run of 9.69 in Beijing.

Tyson Gay, the understated American who was considered Bolt’s biggest threat here, ran the race of his life, setting a personal best and national record of 9.71. But it was not nearly enough as the 22-year-old Bolt got off to a fine start by his standards, kept a slight edge on Gay through 70 meters and then expanded it through the tape with his eyes darting right toward Gay’s lane and then left toward the trackside clock as his long legs kept pumping through the finish line.
