Usain Bolt will be in action today at the World Athletics Championships in Beijing. The world record holder will be lining up for the semi-finals of the 200-metres. The Jamaican will be aiming to win gold in this event for a fourth time in a row. To do that, he’ll need to overcome rival Justin Gatlin who’ll be looking to win back the title he first took in Helsinki 10 years ago.
