No one was injured Monday in the second running of the bulls at the San Fermin festival in this northern Spanish city.
It took the bulls less than 2 1/2 minutes to cross the 850-meter (approximately half-mile) distance from the Santo Domingo stockyard to the bullring.
Monday saw a much smaller number of runners, as many of the tourists who crowded Pamplona for Saturday's start of the festival left town after the weekend.
The event will continue through July 14.
Four people were gored at the 2012 San Fermin festival, while 41 were transported to hospitals and 388 others were treated at the scene by paramedics for a variety of injuries.
More than 4,000 runners turned out some days at last year's festival.
A total of 150 paramedics and doctors, as well as hundreds of other personnel, are working each day to ensure that the runs take place as safely as possible.
The tense and adrenaline-fueled runs are dangerous because some people take part in them after all-night drinking binges, which make them reckless and more likely to get too close to animals that weigh in excess of 500 kilos (1,100 pounds).
Hundreds of other events also have been scheduled for the 2013 edition of the 400-year-old festival, which was popularized by Ernest Hemingway in his 1926 novel "The Sun Also Rises." EFE
