Eight-time Olympic gold medalist Usain Bolt retired from the track in 2017 and is playing soccer now. But clearly, the 32-year-old sprinter hasn’t lost his speed because Saturday at this year’s Super Bowl Experience event, where people can see how they handle NFL combine challenges, Bolt tied the NFL record for the 40-yard dash.

At the NFL combine in 2017, John Ross, now a wide receiver with the Cincinnati Bengals, set the record for fastest 40 time at an incredible 4.22 seconds. And not long after that, Ross challenged Bolt to a race — which they both later laughed off.

But Bolt — the fastest man on the planet with the 9.58 world record in the 100 meters — proved even in retirement, he’s still got it as he tied Ross’ combine record.

He’s not known as the best starter, and he did it in sweatpants and flat shoes, which means Bolt might actually be able to break it if he wore proper attire.

Here are a couple more angles from Bolt’s 40-yard dash.

Of course, the time is not official the way Ross’ combined time is, but it’s beyond impressive nonetheless. And really, what else would we expect from the GOAT?

John Ross Combine Run

Bolt retired from racing after the 2017 world championships, where he finished third in his last 100-meter race and heartbreakingly collapsed in his final race, the 4×100-meter relay. Still, that 2009 still-standing world record and all that hardware speak for themselves.
