London Olympics 2012: The Many Faces of Usain Bolt [SLIDESHOW]

Usain Bolt is more than just the fastest athlete in the world, he is also one of the most entertaining.

Concerns had been raised that the man who dominated the last Olympic games could not repeat his success at London 2012, having suffered a number of defeats in the build-up to the Olympics.

However the Jamaican sprinter, known as much for his personality and charisma as for his running ability, did not disappoint the crowds when he retained his gold medal in the final.

Bolt, 25, was facing one of the most talented group of sprinters ever seen in an Olympic final. Pundits and commentators believed that fellow Jamaicans Yohan Blake and Asafa Powell, and the Americans Justin Gatlin and Tyson Gay, could all claim the gold medal.

However Bolt looked positively laid back in the run-up to the final. As his name was read out before the race began, the reigning champion was captured joking with Blake and playing up to the crowd - dancing in front of the cameras and shadow boxing.

However when it came to the race Bolt was, as he put it, "all business". A little slow out of the blocks, he got into his stride and showed his opposition a clean set of heels, winning the race in 9.63secs.

After winning Bolt joined Blake to celebrate with the crowd, pulling his famous lightning bolt pose and kissing the ground. A glimpse at the slow motion replay showed how focused he was on the victory, and although he did not break his world record, he reminded everyone watching that he remains the fastest man in the world.
