The athletics world has missed Usain Bolt since his retirement in 2017.
Over the course of his decorated career, Bolt elevated the sport to new heights and won eight Olympic gold medals for good measure.
Fans were disappointed to see him bow out at the 2017 World Championships with an injury in the 4x100 metre relay and a bronze in the individual race, but it hasn't effected his mythic legacy.
The Jamaican still holds the world record over 100m and 200m, with the current batch of sprinters failing to come close to his efforts from 2009.
Since hanging up his spikes, Bolt made an unexpected career decision by turning to professional football, making a handful of appearances for the Central Coast Mariners.
Bolt enjoying retirement
There were suggestions that the Olympic champion had lost some of his fitness in retirement, but he still looked in impeccable shape, even if his dreams of playing the 'beautiful game' ended prematurely.
Bolt can't keep away from the track for too long, though, and new footage has emerged of the 32-year-old taking on a very interesting challenge.
FloTrack posted footage of Bolt running 40 yards at a recent event, the same distance over which NFL players test their speed and acceleration.
Bolt races over 40 yards
The current record-holder is John Ross of the Cincinnati Bengals, who clocked an impressive time of 4.22 seconds. But how did Bolt fare over the same distance?
Quite remarkably, he also produced a time of 4.22 seconds, despite tracksuit bottoms and trainers. Remarkable stuff.
The clip has gone viral across Twitter and it makes interesting watching for a certain Hector Bellerin. Check out the full video below:
Even in retirement, Bolt is unstoppable.
Ok, so Bellerin recorded his time over 40 metres, so what does that mean if the two actually raced?
Bolt averaged a speed of 8.66 metres per second throughout the run, meaning he would clock a 40m time of 4.61 seconds if he maintained that pace exactly.
That's pretty remarkable when you consider Bellerin reportedly clocked a time of 4.42 seconds, but that doesn't necessarily tell us the whole story.
The fact that Bolt ran his last time in restricting clothing and having been away from training suggests he could do much better. Plus, his speed would likely increase during the final four metres.
There is also limited information about Bellerin's 40m run, other than word of mouth.
Taking the Bellerin element aside, however, it's still a remarkable achievement from Bolt and goes to show that the world's fastest man can still put athletes from other sports in check.
Come on Usain, you know you want to make a comeback.
