what are the events has Usain Bolt participated in and won medals for? Except running.
Answers
The world's fastest man, Usain Bolt, will run his last ever professional race at the World Athletics Championships in London, which begin on 4 August.
He's been an unstoppable force since winning his first Olympic gold medal in Beijing, China, nine years ago.
Between 2008 and last summer's Rio Olympics in Brazil, Bolt has won an incredible 19 Olympic and World Championship gold medals out of the 20 events he took part in.
It's a medal collection that makes him 'the greatest sprinter of all time', according to the International Olympic Committee.
But why is it not 20 gold medals from 20 races? What happened when world record holder Bolt did not win?

Let's go back to the World Athletics Championships in Daegu, South Korea, in 2011. It's the 100m final.
Usain has looked good so far during the competition. He's been among the fastest sprinters in the qualifying rounds.
As he get ready for the final, the Jamaican does his famous lightning bolt pose and the crowd cheers.

On your marks, set, go!
Usain springs out of the blocks but then the starter's gun goes off. That's not what's supposed to happen.
Disaster, it's a false start!
