Johnny Knoxville looked like a complete moron for challenging a track freak to a race…because when they finally met for an epic showdown – he found himself eating his dust!!

Here’s the deal – the stunt legend played trolling with a 13-year-old Junior Olympian Jaiya Patillo for months…requiring a one-on-one battle to prove he can take him on in a 200-meter sprint.

Well, that day has finally arrived… and let’s just say Knox must wish it didn’t.

Let’s give credit to Johnny for posting footage of the race to his 4 million Instagram followers…because he couldn’t even last a second before falling behind, even though he brought his own pom- cheerleaders for the event.

FYI – Patillo is the highest ranked sprinter in her class … and has won first place at the AAU Junior Olympics and USATF National Junior Olympics in the past. She has also gone viral multiple times on social media for showing off her insane speed.

According to his website, Jaiya’s fastest time over 200 meters is 25.48 seconds…so, yeah, Johnny never stood a chance.

Knoxville was a big sport about it all … but said he liked his chances in a second round.

“And just because you beat me CLOSELY this time Jaiya doesn’t mean there can’t be a rematch!!” said Knoxville.
