Despite being the fastest man never to have won an individual Olympic medal, along with old rival Tyson Gay, Powell won’t be quitting yet.
“I know that my best race is yet to come,” said Powell, who was leading the Olympic final before the injury.
“When I ran the world record, I wasn’t training much. When I don’t train much, I stay healthy, and this year I was training a lot, that’s why I got hurt.”
Powell will not be racing indoors this year, after placing only third in Birmingham last year when he was expected to even break the world record.
He remains a big draw for IAAF Diamond League promoters and believes to be in the shape of his life at next year’s World Championship in Moscow.
Despite missing the 2011 World Championships and this year’s London Grand Prix with a groin injury, he has run the most sub-10 second 100m races in history, 80, and is called the “sub-10 King”.
Powell says he wants to run at least couple more years, but is not sure about the 2016 Olympics in Brazil.
“I don’t know what the future for track holds, at the moment I’m taking it day by day,” he added.
“I have many ideas of what I want to do after track. I’ve already started a couple businesses. I want to open my own car garage. I am also doing real estate.”
Coaching is not in his plans: “I have never thought about coaching, I don’t think it’s something I like very much.”
