Usain Bolt retained his Olympic 100m title by recording the second-fastest time ever to blow away the field.
All the talk beforehand was of Bolt’s injury worries and how his title was under threat from Jamaican compatriot Yohan Blake.
But, despite a sluggish start, he picked up in the middle of the race to power home in an Olympic record of 9.63 seconds with Blake second in a personal best-equalling 9.75sec.
America’s Justin Gatlin came third, also in a PB, in 9.79.
Bolt said he knew from his run in the heat he was in the right kind of form to win the title.
“I was happy,” he said. “When I went out in the first round I felt I could do this.
“I was slightly worried about my start, I didn’t want to false start again.
“I think I sat in the blocks a little bit so I don’t think it’s the best reaction in the world but I executed and that was the key.
“My coach said, ‘stop worrying about the start, the best part of your race is at the end, that’s where you rule’.
“So I stopped worrying about the start and I executed.”
