Rio 2016 Stars: Usain Bolt
One of the most famous sports stars on the planet, Usain Bolt has the chance to achieve Olympic immortality in Rio.
Sport: Athletics (100m, 200m, 4x100m relay)
Country: Jamaica
Date of birth: August 21, 1986
Career highlights: Holder of men's 100m and 200m world records. Triple gold medal winner at both the 2008 and 2012 Olympics and also boasts 11 world titles
Olympic record: Beijing 2008 – 3 x gold (100m, 200m and 4x100m relay), London 2012 – 3 x gold (100m, 200m and 4x100m relay)
Usain Bolt stands on the brink of Olympic immortality at Rio 2016.
The six-time gold medal winner and current holder of two sprint world records has his sights set on a 'triple-triple' in Brazil, in what is scheduled to be his last appearance at the Games.
Bolt burst onto the scene at Beijing 2008 when he claimed 100 metre gold in a then world record time of 9.69 seconds – a landmark he subsequently bettered by 0.11secs. Later in the same Games, he broke Michael Johnson's long-standing 200m record and won a third gold in the 4x100m relay.
His phenomenal feats have seen Bolt become the yardstick by which all sprinters are measured and as yet, nobody has been able to usurp him on athletics' biggest stage.
The 29-year-old defended all three of his Olympic titles in London four years ago, helping Jamaica to another world record in the 4x100m relay.
Many have tried to steal his crown, most notably United States sprinter Justin Gatlin, but Bolt appears to thrive under the pressure. His often-colourful antics on the starting blocks belie the pressure on his shoulders to keep performing.
Such charisma - which was first showcased in his now infamous 'Lightning Bolt' celebration - is part of the reason that he holds such worldwide appeal. But it is his achievements in consistently raising the bar that truly deserve a place in the history books.
"Neither Jesse Owens, Carl Lewis or myself has produced, in my opinion, the consistency and longevity that Usain Bolt has and so to this point he has to be considered the greatest," Olympic legend Johnson told Laureus.com.
"If he's healthy, I don't think anyone can stop him in the Rio."
Bolt too is confident as he looks to retain his 100m, 200m and relay titles one last time in front of his adoring public.
He has already stated that he will retire in the near future, although is yet to decide whether that will be directly after the Games or following the 2017 World Championships.
"Training is going well, I've really stepped up the tempo," said Bolt, who appears to be fully fit again after shaking off ankle and hamstring problems in 2016.
"I'm really focused and I really want it, so I'm just pushing myself and working hard."
Not many would back against him completing a sensational achievement in August and showing the world his trademark 'Lightning Bolt' celebration one more time.
