This 12 year old Australian's name is James Gallaugher and he's really, really fast. He runs the 100m in just over 11.7 seconds. If he could somehow find a way to travel back in time, that would be good enough to win him the gold medal at the Olympics in Athens in 1896
Check out the video below of his pretty awesome performance in a 4x100m recently. When he's handed the baton for the final leg of the race, he appears to be about 20-25m behind the leader. No big deal. He just turns on the jets. Everyone else looks like they're standing still.
