Photo of Cabezudos in Fiesta De San Fermin crowd. El Encierro or Running of The Bulls, San Fermin Festival, Pamplona, Navarra, Spain.
The Cabezudos are headmasks of a big hollow head covering the head and shoulders of the porter. An open mouth enables seeing. The porter (usually a young man) is usually in costume, and holds the mask with a hand. The other hand has a stick with a whip or pig bladder. With it he chases after children or young women. Sometimes he will pause to calm a weeping frightened child. The cabezudos also represent local types.
The Running of the Bulls is the single most characteristic event of the Fiesta of San Fermin. This is the event which has given the Fiesta world-wide fame. It is held at eight o'clock each morning from the 7th to the 14th of July inclusive. It consists largely of young men, although it admits all types, who run in front of the bulls to lead them from their pen up and into the bull-ring. It usually lasts from two to three minutes - although if there are complications due to loose bulls it can last much longer.
The length of the run is some 800 metres (about half a mile) and you don't have to sign up anywhere to take part; you just enter into the run and choose the street where you will run and try to do as best as you can.
