With Usain Bolt and Sir Mo Farah both in action tonight as the World Athletics Championships 2017 get under way at London Stadium (the former Olympic Stadium), see if you can answer these seven questions based on the two legends.

Farah is aiming to defend his 10,000m and 5000m titles for a second time and runs in the 10,000m final tonight to cap the first day. His race is due to start at 9.20pm. Team GB’s Laura Muir runs in the 1500m heats at 8.25pm along with Jessica Judd, Sarah McDonald and Laura Weightman.

Bolt is another big draw of day one as he begins to bring the curtain down on his incredible career. The Jamaican is due to run in the 100m heats at 8.20pm, ahead of Saturday’s semi-final and final - with the latter primed to be his last global individual race.

There is live coverage on BBC television, radio and online, as well as governing body IAAF’s YouTube channel. The event finishes on August 13.
