Johannesburg - Jamaican sprinter Usain Bolt begins his attempt at an unprecedented Olympic Games triple triple on Saturday. The fastest man in the world, who holds the world record in the 100m, 200m and the 4x100m relay and won gold in all of those events at Beijing 2008 and London 2012, is attempting to pull off an unprecedented 'triple triple'.
If he does achieve this feat, he will cement his name as the greatest sprinter in history.
Bolt will be competing, just as before, in the 100m, 200m and 4x100m at the Olympic Games. His closest rival is USA's Justin Gatlin who has posted some fast times this season and has largely been free of injury.
The man who has run the fastest 100m time this year (9.80 seconds) and has consistently snapped at the big Jamaican's heels in major competitions, is part of a fascinating rivalry on track, even if there is lots of respect off it.
Then there is the second fastest man of all time, Bolt's countryman, Yohan Blake, who is something of an enigma. Plagued with injury, he has not run competitively since 2014.
But Blake, who boasts a 100m best of 9.69, is certainly capable of causing an upset at Rio 2016.
Bolt's main rival in the 200m is LaShawn Merritt of the USA, who shocked the athletics community with an incredible 19.74 earlier this year and has clocked under 19.80 three times already in 2016.
But Bolt has said on several occasions that he is aiming to break the world record he set of 19.19. - African News Agency (ANA)
