RIO 2016: Bolt's best 100m runs
The greatest athlete on the planet will go for an unprecedented third straight 100m title on Monday morning (AEST) in Rio.
Usain Bolt, arguably the most recognised sportsman in the world will likely go head to head with America's Justin Gatlin in the final (11.25am AEST).
Bolt runs in the second of the semis at 10.07am with Gatlin in the third semi seven minutes later.
Expect some fireworks if both make it through and the famous Lightning Bolt pose if the Jamaican wins his third gold in the Blue Riband event of the Olympics.
Bolt has had some amazing races over 100m in his career. Here we look at some of the best.
100m, New York 2008
Bolt had not been on the sprinting scene for that long but had earlier in the year announced himself as one of the favourites for Olympic gold with a personal best of 9.76 seconds in his home town of Kingston, Jamaica.
That was in May and just under a month later in a clash with another American rival, Tyson Gay, he took that time down to 9.72 - a new world record - with Gay off the pace, running 9.85.
100m Olympic final, Beijing 2008
Going in as the favourite, all the pressure was on Bolt but he handled all that superbly to win in a time of 9.69 seconds.
He did that time easing down, thumping his chest and with a shoelace untied. The Jamaican was criticised in some quarters for what was perceived as showboating.
The man himself said he was just celebrating his first Olympic title.
100m world championships final, Berlin 2009
As we know, Bolt loves to party and he was up to his usual dancing antics before the final of the world championships in Germany.
But that, as usual, was all a front and he was at his ultimate best in Berlin, destroying a quality field.
Gay was also in superb form, pushing Bolt all the way to force the Jamaican in to breaking the world record, running an amazing time of 9.58 seconds.
The final, which was advertised in Berlin as "Das Duell" between Gay and Bolt, proved to be historic with American running 9.71, the third fastest time in history.
100m Olympics final, London 2012
Bolt had not been at his best in the lead-up to the Games and had been beaten twice by recently crowned world champion and Jamaican teammate Yohan Blake.
Before the final, the re-instated Justin Gatlin ran the fastest semi-final in history, clocking 9.82.
A bottle was thrown from the crowd at Bolt just before the athletes went in to their blocks for the final.
While the Jamaican was not affected by that, he did get off slowly but ran all his rivals down with an Olympic record of 9.63 - the second fastest time ever.
Blake, Gatlin, and Ryan Bailey of the USA all managed personal bests, but Bolt was too good.
100m world championships, Beijing 2015
Gatlin was the form man going into the world final back at the Bird's Nest where Bolt had won his first Olympic crown seven years earlier.
Bolt might not have been at his best but he wanted to send a message, to Gatlin, a drug cheat who had twice been banned from competition.
The American was the favourite, but Bolt was having none of it and held off his rival with an emotional run of 9.79 seconds.
The celebrations from the Jamaican after the win showed just how much this victory meant.
