The Running of the Bulls: reporting the race

This thrilling event dates back to the 14th and 15 centuries. The reason for the “encierro” taking place comes from the necessity of herding bulls to be fought in the afternoon from the corrals in Santo Domingo to the bull ring. But there have been many changes over the years.

At the beginning of the 19th century, the animals were led through the streets by a group of horsemen. The first runners were mainly butchers, and the bullfight took place in the Plaza del Castillo, but it wasn’t until the end of the 19th century when young men began to run in front of the bulls that the “encierro” became the most popular moment of the fiesta.

Today there are “encierros” every morning at 8:00 from July 7 through July 14 during Sanfermines. Again and again, runners risk danger and death along the 848.6 meters that separate the new bull ring from the corrals.

How it unfolds


The day before, at nightfall, in perfect silence and accompanied by oxen, the six bulls that will star in the “encierro” to be fought the next day are herded 440 meters by shepherds from their “los corrals del Gas” in the Rochapea to other corrals in Santo Domingo where the “encierro” begins.

Some 350 passes are given out free of charge from July 6 to July 13 to watch the “encierrillo” from the sidelines at around 10:30. The passes can be obtained from the Town Hall a few days before the start of the fiesta.

A chant to San Fermín

  • Since the year 1962, at 7:55 in the morning, los “mozos” who are running the “encierro” sing to the image of San Fermín, placed in a small niche built into a wall on Santo Domingo, asking for his protection. (“Mozos” is a term used for the women and men who run the “encierro”). With a rolled -up newspaper in hand, which later will be used to guide the bulls, they chant their prayer three times before the first rocket is launched, announcing that the gate to the corrals is open. Red scarves from the “peñas” or San Fermín clubs adorn the niche.
  • The words to the chant are these: “A San Fermín pedimos/ por ser nuestro patrón/ nos guíe en el encierro/ dandonos su bendición” Or in English, “We ask San Fermín, our patron saint to guide us in the “encierro”, giving us his blessing.” It ends with shouts :
    Viva San Fermín! Gora San Fermín!

Rockets in the Air

Two rockets announce to the “mozos” that the “encierro” is beginning. The first one is shot from the gate of the corrals when the clock of San Cernin marks 8:00 sharp. The gates are now open. The second rocket is launched when all the animals are all in the street.
The third rocket comes from the bull ring signaling that the herd is now in the ring, and the fourth, when the bulls have entered the corrals of the ring.

Route of the “Encierrro”

The present route of the “encierro” is divided into seven parts or “tramos”:


  1. Santo Domingo (280 meters). The stretch that begins at the corrals and continues up a dangerously narrow slope to the plaza of the Town Hall. This is the fastest “tramo” with bulls that are fresh and ready to run.
  2. Plaza Consistorial-Mercaderes (100 meters). Fewer incidents occur here as the space in front of the Town Hall is wider with more room to run.
  3. Mercaderes Curve. Mercaderes street finishes with a 90 degree curve to the right. This is where the bulls tend to slip and fall. Since the pavement has been treated with an anti-slide wash, there are fewer falls.
  4. Estafeta street (304 meters). Divided into two “tramos”: Estafeta-Bajada de Javier and Bajada de Javier-Telefónica where the herd tends to separate instead of running together. This is the most popular stretch and the one with the most runners because it is here where many of the most spectacular runs occur. It can be very dangerous because there is no way to escape from the course.
  5. Telefónica Curve (100 meters). Again the “tramo is wider and incredible runs can be had here. But it is dangerous as the herd usually has separated, and a bull alone can cause tragedy.
  6. “Callejón” or Entrance to the Plaza (25 meters). The entrance to the ring slants downward, and the risk of “mozos” falling on top of each other and causing a mountain or “monton” is high, and this small stretch can have fatal consequences . Now and for the last several years, there are small escape holes inside the “callejón”.
  7. Bull Ring. Runners should enter the ring and fan out to permit the animals to more easily enter the corrals. There is still a great deal of danger from bulls that don´t follow their brothers and remain in the ring.


The first fences appeared in 1776 to define the route of the “encierro”. Fences mean safety for runners today. During the first days of June, three carpenters from the company Aldaz Remiro have already begun their work putting fences up all along the 848.6 meters of the route. This is far from easy work as they must put in place 2,700 wooden boards, 900 posts, 70 gates, 200 metal-tipped posts (to prevent the public from climbing onto the fence), and 4,000 wedges to hold the posts in place. Every day 15 planks are also available along the route in case one of the boards should break.


Bulls and Oxen

Six bulls run the “encierro” every morning accompanied by two groups of “cabestros” or oxen. The first eight oxen leave the corrals at the beginning of the “encierro” along with the bulls. At two minutes past eight, the second group of three “cabestros” follow with the objective of “picking up” bulls that have been separated on Santo Domingo. The oxen wear bells around their necks and are usually calm and not dangerous to anyone unless a runner has the misfortune to be stepped on by one. Their task is to gently lead the bulls to the ring.

The runners

Habitual runners of the “encierro” are in excellent physical condition. They have rested the night before, and their minds are concentrated on how they want to run. The average age of a runner is around 28-years-old (although there are veterans of the race who are 60-years-old or more. Runners usually sprint an average of 100 of the 848 meters of the “encierro” route.


A team of 11 shepherds are extremely important to the “encierro” and must be respected and obeyed by everyone in the route. They run behind the bulls with a long cane or stick in their hands to help drive the bulls to the ring in a compact group.

They watch for people who distract the bulls or who could cause danger to others and are easily identified by their dark green polo shirts. On the backs of the shirts is the word “pastor” or shepherd.


This is a protagonist only found in fights in Navarra. Once the bulls have all entered the ring, the “doblador” (sometimes a retired bullfighter) tries to lead the animals into the corrals with capes in their hands. There are four of them.


Public Safety

Around 160 police agents from Pamplona work for safety in the “encierro” . Some 120 are from the Municipal Police. At 4 am, they begin to clear people from the route so that the streets can be cleaned and so the carpenters can complete their work on the fences. The agents also remove people who have positioned themselves on the first fence, as this is reserved for healthcare workers, police and accredited journalists and photojournalists. It goes without saying that anyone who has had a bit too much to drink is removed.


There are 16 stations for accidents and emergencies manned by 165 healthcare professionals. In addition to doctors, there are Red Cross workers, volunteers from the DYA and even firemen.

The hospitals of Pamplona are some of the very best to treat any kind of wound from a bull or accidents and are on red alert every morning. In addition, there are 15 ambulances – nine of them with medical equipment – parked in strategic areas.

Where Should I Watch the 'Encierro'?

There are several different ways to watch the running of the bulls. One is from the second fence (the first is reserved as indicated above), and it is free. You should be there at least two hours beforehand.

Another option is from the ring, itself. For just six euros, you can watch the “encierro” and the entrance of the herd into the ring on two gigantic screens. Following the “encierro” calves are released for the pleasure of those seeking minor dangers.

Estafeta street doesn´t have any protective fences, but balconies along the way are excellent places to watch, probably because of the increased danger and necessity of good running. You have to rent your space, which is shared with others, and usually comes with breakfast.

Others opt for watching the “encierro” live on television or listening to a live radio broadcast. RTV has been transmitting the running of the bulls for 30 years.
