PAMPLONA, Spain — One person was gored in the arm and five others were injured during the fifth bull run of this year's San Fermin festival in Pamplona, officials in the northern Spanish city said Thursday.

Regional hospital spokesman Tomás Belzunegui said that the six were in need of hospital care after being injured during the race along the 930-yard cobbled-street course to the bullring.

The most serious injury was suffered by a 27-year-old man from the Spanish city of Valencia who was gored in the arm. The other injuries were from blows received in falls as the crowds of runners tumbled out of the way of the much faster bulls.

The run featuring bulls from the Victoriano del Río Cortés cattle breeder lasted 2 minutes, 49 seconds, making it the longest of this year's festival. The bulls mainly stayed on course behind the steers which guide them through the narrow, twisting streets to Pamplona's bullring, where the bulls will be killed in bullfights later in the day.

In Sunday's running, two Americans were gored.

A 46-year-old man from San Francisco was gored in the neck by a bull, according to local authorities, and 23 year-old man from Kentucky suffered “less serious,” injuries after a bull’s horn pieced his thigh, according to authorities.

The nine-day San Fermin fiesta that was immortalized by Ernest Hemingway in his novel "The Sun Also Rises" attracts about 1 million spectators every year. Most come to party late into the night before watching hundreds test their speed and daring against the bulls each morning.
