A runner is painfully flipped over when a young bull catches him with a horn between the legs, after the completion of the first run of the 2011 San Fermin Fiesta in Pamplona.
The festival of San Fermín (or Sanfermines, Basque: Sanferminak) in the city of Pamplona (Navarre, Spain), is a deeply rooted celebration held annually from 12:00, 6 July, when the opening of the fiesta is marked by setting off the pyrotechnic chupinazo, to midnight 14 July, with the singing of the Pobre de Mí. While its most famous event is the encierro, or the running of the bulls, which happens at 8:00 am on July 7th, the week-long celebration involves many other traditional and folkloric events. It is known locally as Sanfermines and is held in honor of Saint Fermin, the co-patron of Navarre. Its events were central to the plot of The Sun Also Rises, by Ernest Hemingway, which brought it to the general attention of English-speaking people. It has become probably the most internationally renowned fiesta in Spain. Over 1,000,000 people come to watch this festival.
