Spain's Red Cross says at least one person has been injured as thousands of people tested their bravery and speed by dashing alongside six fighting bulls in the fourth bull-run of Pamplona's San Fermin festival.

Spokesman Jose Aldaba says there are no reports of gorings in Friday morning's run, but one person has been hospitalized with a hand injury.

Four people — two Americans, an Australian and a Briton — have been gored since the runs started Tuesday.

The nationally-televised run sees people racing with six bulls along a narrow 930-yard (850-meter) course from a holding pen to the city's bull ring.

Friday's dash lasted 2 minutes, 24 seconds.

The nine-day fiesta was immortalized in Ernest Hemingway's 1926 novel "The Sun Also Rises" and attracts thousands of foreign tourists.
