Sprinter beaten by 8-year-old Youtude sensation

He’s that fastest man in the world, feared by top sprinters all over the world.

For 8-year-old Demarjay Smith, Usain Bolt is beatable, very beatable.

Demarjay Smith is now a Youtube sensation after a video of him training his friends went viral.

He was a guest on The Ellen DeGeneres Show where he boasted that he can beat World Record holder, Usain Bolt to a race.

Bolt, who has won 17 gold medals in the Olympics and World Championships, surprised the young fitness guru and they took to the track.

"C'mon Usain don't be scared of me," he told Bolt.

As the pair headed for the finish line, Bolt feigned a hamstring and allowed the 8-year-old to win.

Bolt also sat down with Ellen during the show and revealed that next year Olympic Games in Rio de Janeiro will be his last.
