Eight-time Olympic gold medallist Bolt confirmed his final plans today ahead of his retirement. "My aim is to win in London. I want to retire on a winning note," the sprinting legend said. The World Championships take place from August 4 to August 13 at the London Stadium. The men's 100m final is due to place on August 5 while the men's 4x100m relay takes place on the following Saturday. Bolt has won the 100m, 200m and 4x100m gold at the past three Olympic Games.
