KINGSTON (AFP) - Usain Bolt says he has considered the possibility of extending his remarkable sprinting career to the 2020 Olympics - but is targeting a history-making new world 200m record at this year's Rio de Janeiro Games first.
The Jamaican sprint star has repeatedly said he plans to hang up his spikes after the 2017 World Championships in London, bringing the curtain down on a record-breaking career that has included six Olympic gold medals.
However, the 29-year-old told Television Jamaica in an interview aired on Sunday that his coach Glen Mills had suggested he was capable of running in a fourth Olympics if he chose to.
"The coach says I can go on to even the next Olympics in 2020," Bolt said. "But I'm not gonna say what I'm gonna do. My coach says I should stop talking about it all the time, let's just go through these two years and see what happens."
Bolt revealed he is targeting a new world record in the 200m, hoping to become the first man to duck beneath 19 seconds.
"If everything goes as planned it's going to be an awesome Olympics," he said. "That's the main aim. Everyone wants me to win again, but what they really want to see is records.
"One of the big records I want is the 200. What I want is sub-19 - the first man to ever have done it, it would be a game-changer."
