Every year from July 7th-14th thousands pack into Pamplona to start Spain's most famous bull-running fiesta to honour Navarre capital's patron saint, San Fermin. Spain stages more than 3,000 fiestas (festivals) each year but the 7 days of bull-running are the favourite in terms of spectacle and excitement.
After the daybreak of July 7th, runners (mainly young men) gather at the bottom of Santo Domingo, which is the starting line. They crowd together and sing to the image of San Fermin which is placed in a niche on a wall.

Then, as a rocket goes off, a number of fighting bulls are let out onto the streets. A second rocket is then let off to make sure everyone knows the bulls are loose in the street. The bulls run along the narrow street 825 metres (half a mile) to a bull ring. The runners dash along in front of the bulls, aiming to feel the breath of the bull on their backs, getting as close as possible - all whilst trying to avoid getting gored by their sharp horns.
