Botswana's Isaac Makwala has the chance to go for World Championships gold today, but he remains aggrieved at his exclusion from his favoured 400 metres on medical grounds.

Botswana’s Isaac Makwala will go for World Championships gold after overcoming illness, quarantine and two races in little more than two hours to qualify for today’s 200 metres final.

Usain Bolt ducked under 10 seconds for the first time this year to win his last ever race outside of a major championships.

The morning after collecting his 100m gold in the Olympic Stadium, Usain Bolt reverted to his finest showman mode at the start line of the 200m preliminaries, offering his 80,000 disciples an extravagant version of his trademark lightning bolt pose.
