Usain Bolt was the world's fastest man in Beijing, and he will repeat that performance in the 100-meter dash later today in London.
However, the first time he lost (in the 2011 World Championships), it was due to a false start, not his performance on the track.
The second time he was defeated, it was in the Jamaican Olympic Trials—an event in which all he had to do is finish in the top three to qualify, so there was no reason for him to push and risk injury when his spot was all but assured.
This time around though, the biggest prize in track is on the line—Olympic gold, not to mention the title of world's fastest man.
With these two awards on the line, you won't see Bolt mess around.
In 2008, when he stormed onto the scene, he let up before he reached the line and still broke the world record.
This time around, however, you won't see him do that. The competition is just too good.
Blake has proven he can beat him, and Americans’ Tyson Gay and Justin Gatlin have the speed to pull the upset.
All of these runners are talented, but still, none have the pure natural abilities of Bolt.
His 6'5" frame allows him to take unbelievably long strides that are perfect for back half speed. If that wasn't enough, he also has the explosiveness of more compact runners, allowing him to accelerate quickly.
He only has one real flaw, reaction speed off the gun: An issue that usually is associated with lack of focus.
He doesn't often have slow starts, but when he does, it puts him in a huge hole.
However, in the Olympic final, he will get out well.
Then, less than 10 seconds later, he'll be the back-to-back Olympic champion in the 100.
