Origins and Civic Calendar of San Fermín
The Fiestas de San Fermín take place annually in Pamplona, the regional capital of Navarre, commencing at twelve o'clock noon on July 6 and concluding at midnight on July 14. The modern celebration originated from a historical merger of three medieval traditions: liturgical observances honoring saint patron figures, regional agricultural cattle trade fairs, and seasonal bullfighting exhibitions. In 1591, municipal councilors and diocesan authorities permanently transferred the patron saint feast day from its damp autumn date on October 10 to July 7 to secure drier summer weather for public festivities.
The festival officially opens with the Chupinazo pyrotechnic rocket launched from the town hall balcony in Plaza Consistorial before crowds dressed in traditional white clothing with red neckerchiefs. In January 1980, Spain Secretariat of Tourism formally designated the Fiestas de San Fermín as an official Fiesta of International Tourist Interest. The festival officially draws to a close at midnight on July 14 in Plaza Consistorial as assembly participants sing the mournful anthem Pobre de Mí and untie their festive red neckerchiefs.
The Encierro Course and Double Wooden Barriers
The morning encierro bull run is conducted daily from July 7 through July 14, commencing at precisely 08:00 following two warning pyrotechnic rocket discharges. The designated encierro route spans 875 meters across narrow urban streets from the Corrales de Santo Domingo through Plaza Consistorial, Calle Mercaderes, and Calle Estafeta before entering the arena. Municipal carpenters construct a heavy double wooden barrier along the 875-meter route using approximately 900 vertical timber posts and 2,700 horizontal pine planks.
The intermediate security space between the inner and outer timber fences functions as an exclusive evacuation corridor restricted to medical personnel, police officers, and accredited media photographers. Municipal sanitation teams treat the ninety-degree right turn from Calle Mercaderes into Calle Estafeta with a specialized anti-slip resin solution to reduce bull sliding on cobblestones. Municipal carpentered timber barriers are inspected and secured with timber wedge keys each morning, with selected gate sections temporarily disassembled daily to enable urban delivery vehicle transit.
Pastoral Handling and Six Fighting Bulls
Each morning running features six mature fighting bulls from an accredited livestock estate accompanied by six castrated steer guides, known as cabestros, that maintain herd cohesion. A sweeping sweep team of three additional bullocks is released two minutes after the main herd to gather any disoriented or isolated animals remaining along the course. Professional pastoral herders known as pastores run behind and beside the animals carrying flexible hazel wood rods to prevent human runners from touching, inciting, or turning the bulls.
Minutes before the 08:00 rocket launch, runners assemble before a wall shrine niche in Cuesta de Santo Domingo to sing a traditional chant to Saint Fermín three times requesting divine protection. Without isolated or fallen animals, the collective herd traverses the 875-meter cobblestone course in an average duration of approximately two minutes and thirty seconds. Municipal ordinances strictly prohibit runners from participating while intoxicated, carrying filming equipment or backpacks, touching animals, or running behind the pack into the arena tunnel.
Municipal Healthcare and Crowd Safety Logistics
The specialized emergency medical operation stationed along the 875-meter encierro course deploys over three hundred healthcare personnel, including trauma physicians, nurses, and Red Cross volunteers. Emergency authorities station sixteen medical intervention posts along the course, distributing trauma response stations at intervals of roughly fifty meters to guarantee immediate roadside stabilization. A dedicated fleet of more than twenty emergency ambulances, including mobile intensive care ambulances, occupies preassigned egress streets with clearance corridors directly to the Hospital Universitario de Navarra.
While superficial contusions and abrasions represent more than 85 percent of all injuries treated, specialized surgical teams remain on alert to manage severe horn puncture wounds, known as cornadas. The municipal police force collaborates with the Policía Foral and the Guardia Civil to enforce mandatory perimeter sobriety checkpoints and filter unauthorized spectators out of the race precinct. Since systematic municipal injury keeping commenced in 1910, sixteen participant fatalities have been documented in the Pamplona encierro, spurring modern protective barricades and medical protocols.
