Usain Bolt has widely been regarded as the fastest man of all time, breaking all the sprinting world records in his path and dominating the Olympics when he competed.

He was at the peak of his powers towards the back end of the 2010s and set records which other sprinters have been setting their eyes on, with no one able to come close to the Jamaican.

However, that could be about to change thanks to Fred Kerley who has shared a clip of him in training, running the 150m, posting a scary time.

The world record set by Bolt clocked in at 14.35 seconds, with Tyson Gay second with 14.41 seconds and Walter Dix back at 14.65 seconds.

Taking that into account, the time Kerley has claimed is ridiculous and if it is accurate, the next major events could be interesting with the American on track to break the records we didn’t think could be broken.

His clip from training is claiming that he posted a time of 14.01 seconds, at over 3 tenths up on Bolt’s time, not only breaks the record but absolutely smashes it.

Although he claims to have run the 150m in that time, it’s hard to determine whether his claims are genuine or not.

 Regardless of the accuracy, there’s no records for what you do in training, so it won’t be recognised as such, but people aren’t convinced by the credibility of Kerley’s claims.

First of all, it was hand timed, so it will be inconsistent, every re run of the video will lead to you getting a different time, it will never be truly accurate as you rely on human reactions for it.

We don’t know if he was helped by the wind or if he actually ran 150 metres, we can’t see any distance markings on the video either, so we just have to trust his claims.

Also, we don’t actually know where his sprint ends from the video, so we can’t even time it ourselves, it’s basically impossible to determine the accuracy of his claims.

You can see the video posted to YouTube below, including having a read of the comments section where I think it’s safe to say the viewers are slightly sceptical of Kerley’s timing.

If he is genuinely running that fast then the times he’ll be setting in competition will be worth keeping an eye on, records will surely begin to tumble for fun.
