Fans have only just noticed a crazy detail in Usain Bolt's world record achievement during 2008 Olympics

Fans have only just noticed a crazy detail in Usain Bolt’s stunning 100-metre world record run at the 2008 Olympics.

Back in 2008, all eyes were fixated on Bolt as he looked to break the world record and clinch the gold medal inside The National Stadium in Beijing.

The Jamaican superstar went on to break the world record after clocking a stunning time of 9.69 seconds.

However, it was later spotted that when Bolt crossed the line, his shoelace was untied.

Reacting on social media, one fan said: “Mr record maker and breaker Usain Bolt.”

Another tweeted: “I doubt if there could ever be anyone else like this in our generation ever again.”

A third fan added: “Mad how he did that and I can barely walk with my shoes untied.”

Someone else wrote: “The excitement watching Usain Bolt at the Olympics is somthing that will stay with me forever. The magic of the Olympic games.”

A fifth commented: “That's why. The flapping laces make you run faster.”

Another fan said: “While also celebrating before the finish line! What a legend.”

In 2009, Bolt set a new record time when he ran the 100 metres in 9.58 seconds during the Berlin World Championships.

Speaking about Bolt crossing the line with his shoelace untied, four-time Olympic medallist Ato Boldon said: “That was Bolt though, right?

“His top is not tucked in to his shorts, (his) shoes are untied (and) he takes the last third of the race off.”

He added: “Good TV, bad sportsmanship. I don't know if I understood that night.

“I think the beauty of it negates him (not just) just running through the line. Because we don't have (another) race like that in the sport. Ever.”

In 2017, after a glittering career, Bolt’s last race ended in disappointment as he pulled up injured whilst running the anchor leg for Jamaica in the 4x100 relay race at the World Athletics Championships.
