Watch crazy moment high school athlete is PUNCHED in back of the head during race at Florida track meet

A HIGH-SCHOOL runner was left in a heap after being sucker-punched DURING a race last weekend in Florida.

Images from a shocking viral video see the athlete hit the deck after receiving a brutal punch from behind to his head.

Shocked onlookers in the crowd could barely believe their eyes at the events which unfolded during the Tohopekaliga Tiger Invitational in Kissimmee.

The stricken athlete has not been identified but the host school claims no Osceola County students were involved.

, the runner in red and white was leading the race and had been involved in a collision with his assaulter on the previous lap.

Witnesses report that the man who threw the punch was standing on the track and the runner had previously shoved him out of the way.

He is not believed to have been part of the long-distance race.

And when the race leader came round following another circuit, he was sucker-punched hard in the back of the head.

The video continues after the confrontation, with the remaining members of the field running past the fallen athlete.

One supporter in the stands is heard shouting “are you f***ing kidding me?” as the race continued.

Another gasped “did you see that?”, while others simply screamed at the shocking spectacle unfolding in front of them.

Local police were reportedly called to the scene after the race, but there has been no confirmation any charges were filed.

The teen eventually rose to his feet and was able to reach the finish line.
