Take time to learn as much as possible about this dangerous event and know what steps to take for your safety and the safety of the other runners. 

The encierro is not for everyone. It requires a cool head, good reflexes and physical fitness.  The risk is serious.  It is impossible to run the entire distance of the encierro.  Each runner must choose a section of the course. 

1. No runner may be under 18 years of age.
2. Wear suitable clothing and footwear for safety.
3. Cameras and backpacks are prohibited. Do not run carrying any object that could get in the way.
4. Do not run behind the bulls or run in the opposite direction.
5. There are only two entrances to the route, which is completely fenced off with a double fence.  The first fence is for withdrawing runners, police and medical services; the second fence is for the general public. The runners’ entrances to the route are closed off at 7:30 a.m.
6. Follow police instructions for the safety of all runners.
7. Do not take shelter before the bulls are set loose. It can distract the bulls if they are surprised by runners jumping out from blindspots or doorways along the run. 
8. You must run in a straight line. Do not stop in front of other runners or move across their path.
9. Never incite the bulls or draw their attention. A good runner never touches the bulls, but runs with them from a cautious and respectful distance.
10. Do not run drunk.
11. A runner should decide beforehand at which point of the course he or she will withdraw from the run. Do not stop suddenly. Do not watch from behind the first fence or in a doorway, or in any other way prevent other runners’ ability to find safety.
12. Leave space clear for runners following you.  On entering the bullring, take shelter behind the fencing as quickly as possible.
13. Do not incite the bulls. The bull ring can be an especially dangerous area. Leave the ring clear for the herders and dobladores to do their job.
