This live feed is in Pamplona for the famous Running of the Bulls:
The purpose of this event is the transport of the bulls from the off-site corrals where they had spent the night, to the bullring where they would be killed in the evening. Youngsters would jump among them to show off their bravado. Spanish lore says the true origin began in North-eastern Spain during the early 14th century. While transporting cattle in order to sell at the market, men would attempt to speed the process by hurrying their cattle using tactics of fear and excitement. After years of this practice, the transportation and hurrying began to turn into a competition, as young adults would attempt to race in front of the bulls and make it safely to their pens without being overtaken. When the popularity of this practice increased and was noticed more and more by the expanding population of Spanish cities, a tradition was created and stands to this day.
The Pamplona encierro is the most popular running of the bulls in Spain and is broadcast live by two national television channels. It is the highest profile event of the San Fermin festival, which is held every year from July 6–14. The first bull running is on July 7, followed by one on each of the following mornings of the festival, beginning every day at 8 am. Participants must be at least 18 years old, run in the same direction as the bulls, not incite the bulls, and not be under the influence of alcohol. In Pamplona a double wooden fence is used in those streets where there is enough space for it, while in other parts the buildings of the street act as barriers. It is composed of around three thousand separate pieces and while some parts are left for the duration of the fiesta others are mounted and dismounted every morning.
