“It was wonderful,” Bolt, 25, said. “I knew it was going to be like this. There wasn’t a doubt in my mind.”
It was the fastest collective 100-meter race in history, with seven of the eight finalists running under 10 seconds. And four years after Bolt won gold at the Beijing Games, he again crossed the finish line with everyone else looking at his back. He had promised that these Games would again be his stage, and so far, he has brought down the house.
“It means one step closer to becoming a legend,” Bolt said.
He became the first man to successfully defend his Olympic 100 title in competition on the track. Carl Lewis won at the 1984 Los Angeles Games and finished second at the 1988 Seoul Olympics, then was awarded gold after the Canadian sprinter Ben Johnson tested positive for steroids.
