The Running of the Bulls began as a medieval cattle drive to Pamplona’s bullring, then grew into a saint’s day festivity and modern spectacle.
If you have watched clips and wondered how anyone came up with the idea of sprinting in front of a mass of horn and muscle, you are not alone. The story began as a practical job for workers who needed to move bulls through town, then slowly turned into the headline event of the San Fermin festival.
How Running Of The Bulls Started In Pamplona
The roots of the Running of the Bulls lie in the Middle Ages, when local ranchers and drovers had to get fighting bulls from fields outside Pamplona into the town. The animals were headed for early versions of bullfights and needed to reach simple rings or pens near the centre. Streets gave the most direct route, so the herd moved along narrow lanes at first light, pushed on by horsemen and helpers on foot.
Over time, young locals began to run alongside these cattle drives. They jumped in as a dare, teasing the animals and racing ahead of the horns to show raw nerve. Town leaders tried to keep order, yet the habit stuck. By the sixteenth century, records from Pamplona already mention people running ahead of the bulls as they approached the ring.
| Period | Main Feature | What Changed |
|---|---|---|
| Medieval era | Cattle moved from fields into town at dawn | Purely practical livestock transport |
| 14th–15th centuries | Youths begin to run beside the herd | Displays of nerve appear around work tasks |
| 16th century | Bull runs linked to local feast days | Running starts to blend with town celebrations |
| 1591 | San Fermin feast moved to July | Better weather and trade fair boost attendance |
| 18th century | Route fixed through old town streets | Encierro gains a recognisable layout |
| 20th century | Radio and television coverage | Worldwide audience grows year by year |
| 21st century | Tourism and safety rules expand | Local regulations and global debate shape the runs |
How Did Running Of The Bulls Start? From Work To Ritual
At first the event had no special name. People spoke simply about leading the bulls through town toward the ring. Spanish terms such as encierro, meaning a confinement or penning, later came to describe the whole process of bringing the animals in from outside the walls. The thrill for locals came from slipping into that routine task and turning it into a show of nerve in front of neighbours.
People who ask ‘How Did Running Of The Bulls Start?’ often picture a single bold decision, yet the answer lies in slow changes. As feast days grew in number, morning cattle runs lined up with church events. Bulls for afternoon corridas shared dates with trade fairs and processions, turning practical work into shared ritual. In Pamplona, that blend of faith, trade, and bulls produced the week that frames San Fermin.
From Cattle Drive To Festival Centrepiece
The move that locked everything together came in 1591, when Pamplona shifted the main feast of San Fermin from autumn to early July. Summer weather suited outdoor events and trade, so crowds grew quickly. Bulls remained in the middle of the week, and the morning encierro became the natural way to bring them safely to the ring in time for the late afternoon fights.
During the eighteenth century the route settled into a form that visitors would still recognise today. City workers put up wooden fences along several stretches so that the bulls could not break away into side streets. The dash now ran from bull pens near Santo Domingo, through the old quarter, and into the stone bullring. This layout turned everyday streets into a temporary track.
The municipal site in Pamplona still sets out this history in detail, with maps of the encierro route and safety advice for visitors on the official encierro page at Pamplona city hall.
Hemingway And The Global Fame Of The Bulls
The festival might have remained mostly local without outside storytellers. In the 1920s, Ernest Hemingway visited Pamplona and found the week of music, street life, and bull events gripping enough to anchor his novel The Sun Also Rises. That book carried scenes of the encierro to readers across Europe and North America and drew early waves of foreign visitors.
Later, travel writers, photographers, and film crews added their own images and tales. Once television crews began to broadcast the runs live, the Running of the Bulls turned into a yearly media event. As more tourists came, Pamplona refined crowd management, medical response, and local rules.
What The Running Of The Bulls Looks Like Today
On each morning between 7 and 14 July, a rocket at eight o’clock signals the release of the bulls from their holding pen. The animals and steers charge along an enclosed course of just under 900 metres, covering cobbled streets lined with balconies and packed barriers. Most runs last two to four minutes, yet every second feels full for those on the route.
Participants must be at least eighteen years old and sober, and they can only run in the same direction as the herd. Local police and volunteers line the route, while medical staff wait in side alleys and at the bullring entrance. Injuries from falls happen every year, and gorings still occur, though records show that fatal incidents remain rare across a long period.
Official guidance from Pamplona stresses that only fit, confident runners with quick reflexes should take part, and that anyone unsure should watch from balconies or safe viewing spots instead.
Traditions, Dress, And Local Atmosphere
Runners follow simple dress customs that visitors soon notice. Most wear white shirts and trousers with a red waist sash and matching neckerchief. The colours connect both to Saint Fermin and to older rural clothing. Many locals sleep little during the week, spending nights at concerts and bars before gathering at dawn to sing to the saint near the start of the route.
The encierro does not stand alone. It fits inside a packed week that includes religious processions, music bands, parades of giants and big heads, street parties, and nightly fireworks. For many residents, the run is one event among many that bring friends, family, and visitors together in shared rituals each July.
Debate, Safety, And Animal Welfare
The Running of the Bulls sparks strong opinions. Defenders argue that the encierro forms part of a long local heritage and helps sustain rural breeding farms and related trade. They also point out that bulls run only once in the morning and then appear in the ring that afternoon. Critics point to stress and injury to animals, as well as the risk to runners and spectators.
Animal welfare groups have staged protests in Pamplona and other towns with bull events. They argue that modern entertainment does not need animals at all, and they promote alternative summer festivals without bull runs or corridas. Debates over these points take place in local councils, Spanish media, and international outlets each year when the festival begins.
Rules Every Runner Needs To Respect
Anyone thinking about stepping onto the route should study current rules issued by Pamplona each year. Some of the core rules stay constant. Runners may not touch or harass the bulls, cannot bring cameras or phones into the track, and must leave the route at the first safe exit once they are tired or have fallen behind. Throwing objects, blocking other runners, or trying to guide the animals is banned.
Planning A Trip To See The Running Of The Bulls
Many people now travel to Pamplona with the Running of the Bulls at the centre of their plans. Air and rail links connect the city with major Spanish hubs, and buses from nearby towns fill up early in July. Hotels and apartments sell out months ahead, so early planning matters. Some visitors stay in nearby towns and travel in each day, while others book package trips that include balcony spots, guides, and transport.
| Choice | Main Advantage | What To Watch Out For |
|---|---|---|
| Balcony spot on the route | Safe view of the bulls and runners | High prices and early bookings required |
| Street level behind barriers | Strong sense of the noise and speed | Arrive early and expect crowding |
| Bullring seat for the finish | See the herd enter and watch morning displays | Sun exposure and limited shade |
| Staying inside the old town | Right in the middle of the action | Night noise and higher room rates |
| Staying in a nearby town | Quieter nights and lower prices | Need to plan daily transport |
| Running the route yourself | First hand view of the encierro | High risk of falls and injury |
| Watching on television | Zero physical risk, good replays | Less sense of the town atmosphere |
Making Sense Of A Historic Yet Controversial Event
The question “How Did Running Of The Bulls Start?” leads straight into wider questions about tradition, risk, and change. The event began as a simple way to move animals to the ring, then absorbed local faith, trade, and street life. Over centuries it picked up layers of song, dress, ritual, and argument. Today, any visit to Pamplona during San Fermin brings those layers together in one intense week.
Whether you choose to run, watch from a safe spot, or stay away from the bulls altogether, knowing the history will reshape how you react to the crowds and the morning rocket. The Running of the Bulls is not just a three minute dash through narrow streets. It is the visible tip of a long story that still adds new chapters each July.
