Bolt ran the race in 9.63 seconds, followed by Jamaica's Yohan Blake at 9.75 and America's Justin Gatlin at 9.79. (Those were personal bests for all three athletes.)

Afterward, Bolt hit Twitter to talk about his performance.

"Thanks to all the fans for supporting and believing," he wrote. "You have been a part of the journey.. 'To the World Me Say.'"

Bolt also retweeted a message from CNN's Piers Morgan, who referred to an interview in which the runner was called a "legend." Bolt, whose Twitter account describes him as "the most naturally gifted athlete the world has ever seen," didn't disagree.

"You called it man..@piersmorgan: BBC MAN: 'You're a legend..' USAIN: 'Alright.' Exit.” he wrote.

After the race, Bolt also sat down to answer reporters' questions during a news conference, during which he revealed that he ate McDonald's before the race.

"Don't judge me," he said, as quoted by Yahoo Sports.

He also was asked how badly he wanted to be remembered as a legend.

"Do I really need to answer that question?" he said.
