“The young man was on the path of a bull run which he was filming with his mobile phone,” said Jesus Hijosa, mayor of Villaseca de la Sagra, where the accident occurred.
“A bull surprised him from behind and gored him in the neck,” he told AFP.
Villaseca de la Sagra is one of many towns across Spain that host annual festivals where crowds of people run ahead of a herd of bulls.
Another young man was killed during a 2010 bull run in the town.
One of the most famous bull runs is in Pamplona, which was immortalised by US author Ernest Hemingway in his 1926 novel “The Sun Also Rises”.
The 32-year-old man who died Sunday was from a neighbouring village and had come with friends to Villaseca de la Sagra on Saturday for the run, the mayor said.
“This sends shivers down our spine… we organise these events as a tradition, so that people can enjoy them, but these things happen,” Hijosa said.
“Bulls are dangerous animals and when there are a lot of people some don’t pay attention… you have to have your wits about you.”
Fifteen people have been killed in bull runs in Pamplona since 1911, where many foreign tourists join in the tradition.
