This is video of a track & field event where a female competitor makes a big mistake, which led to a big collision.

The track participant, obviously unaware of her surroundings, wonders onto the infield of the track, where a man participating in either the long jump, or the triple jump, was running full steam, as he prepared to jump.

The man, who was running with his head down, looked as though he never had any idea the lady was there. The guy in the orange jacket in the background sure did though. It looked as though he saw the collision happening before it took place.

I bet she never makes the same mistake again.
