The fiestas are organized by Pamplona City Hall. They are responsible for the official program for Sanfermin fiestas, which is published around the end of June. However, other groups may also organize their own events, which run alongside the official events. The running of the bulls, the txupinazo opening rocket to launch the fiestas and the “Pobre de Mí” (Poor me) event to bring down the curtain on the fiestas are all organized by City Hall and they all form part of the official program.
