Health authorities in northern Spain's Pamplona say two people were injured in Tuesday's speedy bull run, although there were no gorings, unlike in previous days.
The race along the 930-yard (850-meter) cobbled-street course to the bullring lasted just over 2 minutes, the fastest so far this year.
Four people — two Americans and two Spaniards — have been gored since the daily races started on Sunday.
Tomás Belzunegui, deputy director of the regional hospital, says that a man who fractured his ankle badly on Tuesday will likely remain hospitalized but that a runner who hit his head against the floor will likely be discharged soon.
The nine-day San Fermin fiesta attracts revelers from around the world who test their bravery and speed dashing through the streets with six fighting bulls.
