The well-known Spanish tradition, the running of the bulls, took place on Monday and ended up causing only minor injuries.

Six bulls galloped down the narrow and crowded streets of Pamplona where thousands of people watched the third day of the annual San Fermin festival.

Six Spaniards and a 30-year-old American runner, who injured an elbow, were treated at hospitals on day three of the festival, the local government said.

The bulls completed the 930-yard route from a corral on the outskirts of town to Pamplona's central bullring in a mere 2 minutes and 46 seconds, officials said.

The bulls that took part in Monday's run were from breeder Fuente Ymbro. The heaviest of the animals weighed 1,422 pounds.

Though several runners fell directly in the path of the bulls at a bend in the route known to aficionados as "where Mercaderes and Estafeta streets meet" the animals jumped over them.

Pamplona's population of 200,000 increases significantly during the San Fermin festival.

Around 800,000 visitors came during the weekend, local government spokesman Patxi Cervantes said. The events are held every morning between July 7-14.

The festival in this northern city, known for its all-night street parties, dates back to the late 16th century, though its roots reach back to when Christianity first came to Spain.

It gained worldwide fame in Ernest Hemingway's 1926 novel "The Sun Also Rises."

Since record-keeping began in 1924, 13 people have been killed during the runs.

The last was a 22-year-old American, Matthew Peter Tassio, who was gored to death in 1995.
