He is without doubt the fastest man on the planet.
But is age catching up on Usain Bolt?
He is already 30 years old and what he wants now is to exit in a blaze of glory.
Bolt announced on Wednesday that he is retiring in August.
But he will still run, of course that what he does best, the 100 meters and 4×100-m relay at the World Championships in London, his final event before hanging up his spikes.
An eight-time Olympic gold medallist and an icon of world sport, the Jamaican speed marvel has made one of the most illustrious careers in the history of athletics.
“My aim is to win in London. I want to retire on a winning note,’’ he said.
The World Championships will be held August 4-13.
The men’s 100m final is on August 5, while the men’s 4x100m relay race – which will mark the end of Bolt’s career – will be on the following Saturday.
Bolt has reigned supreme in the 100m, 200m and 4x100m at the past three Olympic Games – Beijing 2008, London 2012 and Rio 2016.
Those feats could have been more emphatic had he not been deducted one gold medal in his unprecedented “triple triple’’ of nine gold medals.
His haul was downgraded to eight after his Jamaican teammate Nesta Carter, who was a member of the quartet which topped the 4x100m in Beijing, tested positive for a banned substance. Carter has made an appeal against the decision.
Still, Bolt’s achievements remain unparalleled. He also owns the world record in the 100m (9.58) and 200m (19.19).
He ran for the final time at his native Jamaica last June, clocking 10.03 seconds to prevail in the “Salute a Legend’’ 100m race before taking a lap of honour in front of a sell-out crowd of 30,000 in the capital city of Kingston.
Before seeing action in London, he will also participate in the 100m at the Diamond League event in Monaco on Friday.
Can someone outrun Bolt when he flexes those powerful long legs in the London trackfest for the last time?
