Usain Bolt claims losing his unbeatable tag in his final race does not tarnish his Forever Fastest legacy.
The Jamaican added a first bronze medal to his golden collection when he joined champion Justin Gatlin and Christian Coleman on the 100 metres podium.
He said he had no regrets at not retiring after completing his hat-trick of Olympic titles in Rio last summer.
“I’ve proved to the world I’m one of the greatest athletes,” said Usain Bolt . “This doesn’t change anything.
“I lost to a great competitor and a young kid who is coming up and is very talented.
“No regrets, I’ve done my part as an athlete to uplift the sport. I’ve done all I can, it’s time to go.”
Usain Bolt, 30, said he gave it one more year “for the fans – they wanted me to do one more season.”
But even that was not enough to persuade him to defend his 200m crown. He has lost only one 200m of 49 in nine years yet said: “It would probably be even worse than the 100m. I’m not in shape to win the 200m.”
Instead he will anchor Jamaica’s sprint relay next weekend then step out into civvy street.
“I’ve shown over the years that I’m unique,” he added. “I do things differently.
“I don’t think there will be another me.”
