A golden era is drawing to a close as Usain Bolt's career comes to an end, but he is not done yet and wants to go out on a high in London.
Usain Bolt will not let his "horrifying" farewell run in Jamaica undermine his confidence going into the World Championships as he seeks to sign off a stellar career in style.
The eight-time Olympic champion reminded his rivals that he remains the fastest man in the world, despite an underwhelming 10.03 seconds over 100 metres on home soil this month.
In the meantime Andre De Grasse who took third in the 100m in Rio and silver in the 200m clocked a wind-assisted 9.69secs in Stockholm to underline his growing threat to Bolt's supremacy, and long-time rival Justin Gatlin won the US trials last week.
But Bolt, who will compete in Wednesday's Golden Spike meeting in Ostrava, was defiant when asked if he would be able to keep up with the competition in his final outing on the global stage in August.
"I am the fastest man in the world so I will say yes to that," he said, before playing down De Grasse's time in hugely beneficial conditions.
