Pamplona's San Fermin Festival kicked off with the Chupinazo, the official opening of the week celebration that involves running with the bulls, otherwise known as the Encierro. Thousands of locals and tourists held up red neckties, signaling the start of the festival. Each day until July 14th, at exactly 8 a.m., anyone can run along the 875 yard route from a corral to the city bullring where then the bulls are fought by professional bullfighters. Since records began in 1924, 13 people have been killed in the runs.
The festival, held since 1591, attracts tens of thousands of people. Many had spent the night drinking and partying.
