This year's first running of the bulls got under way Thursday as more than 1,000 people rushed ahead of six bulls for a half-mile run. Police said 23 people were injured.

The festival, held every year in this northern Spanish city during the feast of San Fermin, was made famous by Ernest Hemingway in his 1926 novel "The Sun Also Rises."

The bulls ran the stretch from the corral to the bull ring in 3 minutes, 20 seconds. More than 1,000 people rushed ahead to stay in front, police said.

During the run, 23 people suffered bruises after being bumped or trampled by the bulls. A young Spanish man lost consciousness and was taken to a local hospital for observation.
