Bill Hillmann, 33, author and writer of a book called “How to survive the Running of the Bulls” was badly mauled by a large bull during today’s Running of the Bulls event. Ironically, Hillmann’s book specifically targeted surviving a charge and evading a mauling.Hillmann was seen in a user-video being pushed to the side by a large crowd, and subsequently trampled by a large bull. The video also demonstrates one of the bull’s horns penetrating into Hillmann’s right thigh.Hillman was only one of four people injured in the entire Running of the Bulls event this year. The other three men , all locals, suffered lesser injuries during the famous event.Hillman , however, might have issues selling his book after this embarrassing incident.
