Usain Bolt has been a defining feature of the Olympics over the past three games, in which he has been unbeaten over the 100m and 200m. 

Not only is he the defending champion, but current world record holder making him the fastest man to have ever lived.

His lightning bolt pose and general charisma made him a worldwide icon, but will he be returning to defend his title in Tokyo? 

Here's everything you need to know about Bolt's legendary career and what he is up to now...

Will Usain Bolt compete at Tokyo 2020 Olympics? 

Unfortunately, Tokyo will be the first games in over a decade where Usain Bolt will not be on the start line. 

One year after winning yet another triple in Rio - gold in 100m, 200m and 4x100m - the sprinting ace retired in 2017 at the age of 30. 

However, he did consider a comeback for Tokyo, telling Wide World of Sports in 2020 that he had approached his coach, who had told him "No, we're not doing it." 

While it's sad for the fans who loved watching Bolt's easy track manner, it means that for the first time since 2008, the gold medals in the 100m and 200m will be up for grabs. 

What is Usain Bolt doing now? 

Bolt is now a dad and, with partner Kasi Bennett, has maximised his surname to pick some thematic names for his children...

Olympia Lightning Bolt was born in May 2020, while twins Saint Leo Bolt and Thunder Bolt were born in June 2021. 

Aside from family life, he had a brief flirtation with the idea of turning to pro football early in his retirement, but he soon abandoned these plans proclaiming his "sports life" was "over". 

He has time to decide what to do next though; with numerous sponsorship deals throughout his career, Bolt is the highest paid athlete in the history of track and field. 

What records does Usain Bolt hold? 

He is the only man to have ever won three back-to-back Olympic golds in the 100m and 200m, winning at Beijing 2008, London 2012 and Rio 2016. 

Bolt also has the title of "the fastest man to have ever lived", holding the world record for the 100m at 9.58 and the 200m at 19.19, both which he ran in Berlin at the World Championships in 2009. 

As if this wasn't enough, he also holds the second fastest time over the 100m, and the Olympic Record in both disciplines.
