Usain Bolt eyes history against Gatlin after Michael Phelps heroics

A day after American swimmer Phelps brought the curtain down on his extraordinary career with a record 23rd gold medal, Bolt will attempt to complete the first leg of an unprecedented "triple-triple" in the 100m at the Olympic Stadium.

With semi-finals scheduled at 9pm local time (10am Monday AEST), Bolt is poised to line up for the final at around 10:25pm (11:25am AEST) where he will aim to clinch a third consecutive 100m crown after wins in 2008 and 2012.

The Jamaican superstar made his opening bow in Rio during Saturday's heats, coasting to victory in 10.07sec.

Usain Bolt has never run a mile

The world’s fastest man may have six Olympic gold medals, but that doesn’t mean he’s perfect.

Far from it, in fact, if you consider his agent Ricky Simms’ most recent shock admission about the Jamaican track star.

For all his celebrity and speed, Bolt has never run a mile.

He’s never run the 1609m middle distance mark. Ever.

The Showdown II: Bolt and Gatlin to face-off in 200m final

After Bolt edged the American by .01 second in Sunday's 100 final, he is now running in his favored race and seeking his record 10th world title overall.

Bolt was grinning widely after crossing in 19.95 seconds, coasting for about 60 meters and checking the stadium screens high up in the stands of the Bird's Nest to see if someone could come close. As usual, none did.

The controversial Gatlin came into the final on a 28-race unbeaten run and apparently relishing his role as the sport's bad guy.

But at the same Bird's Nest stadium in Beijing where Bolt announced himself to the world with two Olympic golds and two world records in 2008, the Jamaican superstar came past a faltering Gatlin at the death to snatch victory by one hundredth of a second.

Bolt's 9.79 seconds was more than two tenths off his world record, but this was a night for athletics to celebrate victories rather than times.

Bolt was trailing for almost the entire race in the biggest showdown in the sport in years. But with gritted teeth, the two-time Olympic champion clawed back into contention and made his giant stride count to win in 9.79 seconds — .01 seconds faster than the American veteran.

"A lot of people counted me out," Bolt said. "So for me to come and win, this is a big deal."

Gatlin upstaged the Jamaican with the top time in the first round, even though the American got a little push from nature with a strong back wind of 2.1 meters per second during his 9.83-second race.

Bolt could count on an adoring crowd but faced a slight headwind as he cruised to a time of 9.96, the fifth fastest overall.

"It was OK. It was not perfect," Bolt said. "I still have some adjustments. Just have to concentrate on my technique now."
