Jamaican sprinter Usain Bolt, who has won eight Olympic golds, is set to run the last race of his glittering career on August 12, 2017 if he qualifies for the 4x100m relay at the World Championships in London. In the run-up to his key 100m event on August 5, he clocked 9.95 seconds at the Monaco meet in July.

Bolt holds the world record for the 100m (9.58 seconds), the 200m (19.19 seconds) and the 4x100m relay (36.84 seconds).

At the Rio Olympics in 2016, Bolt won the 100m in 9.81 seconds, his winning time clearly slowing down. Speaking ahead of his retirement, Bolt said he would like to go out at the pinnacle of his sport when he was “unbeatable, unstoppable.”

He joked that he was still waiting for a call from Manchester United to play football. What comes next for athletics after Bolt? The world will be watching American Christian Cole, who has run fast this year (9.82 seconds), and Canada's Andre de Grasse but Bolt's are very big shoes to fill.
