Running of the Bulls: Pamplona's San Fermín Festival

The Running of the Bulls (encierro) in Pamplona, Spain, is one of the most famous and controversial festivals on Earth. Each morning from July 7 to 14, during the San Fermín festival, six fighting bulls and six steers are released to run 875 meters through the narrow medieval streets of Pamplona's old town, pursued and accompanied by thousands of runners.

Introduction

Pamplona (Iruña in Basque) is the capital of the Navarre region in northeastern Spain, situated at 449 meters elevation on a plateau above the Arga River at the foothills of the western Pyrenees. The city's geography — its medieval street plan, stone buildings, and enclosed plazas — creates the dramatic funnel-like corridor that makes the encierro both thrilling and dangerous.

The San Fermín festival celebrates the city's patron saint and attracts over 1 million visitors during its eight-day run. Ernest Hemingway's 1926 novel The Sun Also Rises brought the festival to international attention, and it has since become one of Spain's most iconic cultural events.

The Encierro Route

• Distance: 875 meters
• Duration: 2–6 minutes
• Start: Santo Domingo corral
• Finish: Plaza de Toros bullring

The encierro route follows a precisely defined 875-meter path through Pamplona's Casco Viejo (Old Town). It begins at the corrals on Cuesta de Santo Domingo, a steep 290-meter uphill stretch where the bulls emerge at maximum speed. The route turns sharply right onto Calle Mercaderes, then negotiates the treacherous 90-degree left turn at Calle Estafeta — the most dangerous point, where bulls often lose their footing on the cobblestones and crash into the wooden barriers.

Calle Estafeta, a narrow 300-meter straight, is the longest section and where most running occurs. The route then enters the Telefónica curve (named for the Telefónica building), another dangerous bend, before funneling into the callejón (tunnel entrance) of the Plaza de Toros bullring, where 19,720 spectators await. The entire run takes between 2 and 6 minutes, depending on whether the bulls stay together or become separated.

History & Origins

• Festival Origin: 12th century (San Fermín patron saint feast)
• First Encierro: 14th century (practical cattle driving)
• Hemingway Effect: 1926 novel The Sun Also Rises

San Fermín began as a religious feast honoring the first bishop of Pamplona, originally celebrated on October 10. In 1591, the city moved the festival to July to take advantage of better weather. The encierro evolved from the practical necessity of moving bulls from corrals outside the city walls to the bullring — herdsmen discovered that running alongside the animals through the streets was faster than driving them from behind.

Hemingway visited San Fermín nine times between 1923 and 1959, and his portrayal of the festival in The Sun Also Rises transformed it from a regional Basque tradition into an international destination. Hemingway's statue stands outside the bullring, and the Café Iruña on Plaza del Castillo, where he wrote, remains a pilgrimage site for literary tourists.

Geography & Climate

• Location: Pamplona, Navarre, Spain (42.8°N, 1.6°W)
• Elevation: 449 m above sea level
• July Temperature: 18–30°C, with occasional heat waves

Pamplona's position at the western edge of the Pyrenees gives it a transitional climate between oceanic and Mediterranean influences. July temperatures are warm but moderated by altitude, with daytime highs averaging 28°C. The city's compact medieval center, built on a bluff above the Arga River, is perfectly preserved and provides the enclosed street corridor essential to the encierro's dynamics.

The Navarre region surrounding Pamplona is geographically diverse, transitioning from the green Pyrenean valleys to the north to the semi-arid Bardenas Reales badlands to the southeast. This geographic crossroads — between the Basque Country, Aragon, and France — gives San Fermín a unique cultural character that blends Basque, Spanish, and French influences.

Dangers & Controversies

• Fatalities: 16 since 1910
• Injuries: 50–100 per year (gorings, trampling, falls)
• Animal Rights: Growing international opposition to bullfighting

The encierro is genuinely dangerous. Since 1910, 16 people have been killed during the running, most recently an American tourist in 2009. Each year, 50 to 100 runners are treated for injuries including gorings, trampling, broken bones, and concussions. The most dangerous points are the Cuesta de Santo Domingo (where bulls run fastest), the Mercaderes-Estafeta corner (where bulls lose footing), and the callejón entrance (where pileups occur).

Animal rights opposition to San Fermín has intensified in recent decades. Anti-bullfighting groups stage annual protests outside the bullring, and several Spanish cities and regions have banned bullfighting entirely (though not Navarre). The encierro itself, while not directly lethal to the bulls, is followed by afternoon bullfights in which the six bulls are killed by matadors — a practice that an increasing number of Spaniards oppose.

Festival Beyond the Encierro

• Duration: July 6–14 (8 days)
• Opening: Chupinazo rocket from City Hall (July 6, noon)
• Activities: Processions, concerts, fireworks, giants parade

San Fermín is far more than the morning bull run. The festival opens at noon on July 6 with the chupinazo — a rocket fired from the balcony of the City Hall into the packed Plaza Consistorial, where tens of thousands of revelers in white clothing with red scarves (pañuelos) erupt in celebration. The opening moment is broadcast live across Spain.

The festival features daily processions of gigantes y cabezudos (giants and big-heads), massive papier-mâché figures paraded through the streets by dancers. Nightly concerts fill multiple stages, and the peñas (social clubs) march through the streets playing music continuously. The festival closes on July 14 at midnight with the Pobre de Mí ceremony, a melancholic candlelit gathering in Plaza Consistorial where crowds sing "Pobre de mí, pobre de mí, que se han acabado las fiestas de San Fermín" (Poor me, the fiestas of San Fermín are over).

Final Thoughts

San Fermín is a festival defined by its geography — the narrow medieval streets, the cobblestone corners, and the funnel-like route from corral to bullring create a unique and dangerous spectacle that has captivated the world for centuries. Whether celebrated or criticized, the encierro remains one of the most visceral encounters between humans, animals, and urban landscape on Earth.
