PAMPLONA, Spain – One thrill-seeker was gored in a leg and five others slightly injured as thousands of adrenaline-fueled runners raced ahead of six fighting bulls in the streets of the northern Spanish city of Pamplona in the first running of the bulls of this year’s San Fermin festival, officials said Saturday.

Runners, in traditional white clothing and red kerchiefs around their necks, tripped over each other or fell in the mad daredevil annual rush along early-morning dew-moistened slippery streets to the city’s bullring.

The gored runner, a 73-year-old Pamplona resident, was taken to a local hospital and five others were treated for cuts and bruises, the regional government of the province of Navarre said in a statement.

The running of the bulls became famous with the publication of Ernest Hemingway’s 1926 novel “The Sun Also Rises.”
