A sport beset by doping controversy, athletics has a saving grace: Usain Bolt. The Jamaican Olympic 100m and 200m champion will be competing tonight at the London anniversary games; an event that will be a celebration of the 2012 Olympics held in London.

It is an opportunity for the UK public to once again salute the great champion and gauge his form before the Rio games in two weeks. He also timed it with the release of his personalised emojis.

With the backdrop of excitement and expectation, there are suggestions that the Rio games could be Bolt’s last outing at the Olympics – and his chance to win three successive 100m Olympic golds. He’s only 29 years old, so many fans will certainly hope to see him grace the tracks for a few more years.

As for his dreams of winning gold at 100m and 200m in Rio to complete his ‘triple double’, the entire world will certainly be adding wind to his sails, if only to witness the now famous lightning bolt celebration for one last time on the Olympic stage.
