On each day of the festival six bulls are released at 8:00 a.m. (0600 GMT) to run from their corral through the narrow, cobbled streets of the old town over an 850-meter (yard) course. AFP.
Ahead of the bulls are the runners, who try to stay close to the bulls without falling over or being gored. AFP.
The festival in honour of the patron saint of Spain's northern Navarra region - SanFermin- dates back to medieval times and combines religious processions, all-night partying and hair-raising daily bull runs. AFP.
