It just might be one of the biggest blunders in recent sports history.
One overly eager fan at the Tour De France caused a major pile up that injured many racers on the first leg of the race.
The unidentified woman was waving her large sign when she turned it so the camera could see it. At that time a racer drove right into it causing him to fall.
The collision caused a domino effect which knocked many other riders around him to also fall.
The woman is currently on the run, but the Tour has announced they are going to sue her when they find her.
