JUSTIN GATLIN

Gatlin had planned to retire in 2020 after competing in his fourth Olympics at the age of 38. However, the controversial American star now plans to extend his career in order to compete in the rescheduled Tokyo Games.

"I think a lot of people think that time is against me or against older athletes in this situation, and it's far from the truth," said Gatlin, who has twice served suspensions for doping offenses during his career.

Gatlin, the 2004 Olympic champion, could face a battle to even qualify given the depth of the US men's sprint squad, with Christian Coleman and Noah Lyles the favorites in the 100m and 200m.

However, there is plenty of time for this pair...

She would not have been alone in Japan as professional skateboarder Sky Brown－only five months older－was hoping to compete for Britain.
