A group inspired by the running of the bulls in Pamplona is planning to unleash bulls in several US cities to sprint through fenced-in courses as daredevils try to avoid being trampled.

The Great Bull Run is set to kick off on Aug 24 at a drag-racing strip south of Richmond, Virginia. A second event is planned for Oct 19 at an Atlanta-area horse park that hosted events for the 1996 Olympics. More events are planned later for Texas, Florida, California, Minnesota, Illinois and Pennsylvania.

Bull runs - when the animals are released to run alongside participants as spectators cheer - are common in Spain and can drum up controversy. Injuries often occur, as do deaths, though they are much rarer. Some groups attack the treatment of the bulls used in the runs.

About 5,000 people have signed up to participate in the Virginia event, and the number is growing by about 50 each day, said Rob Dickens, co-founder and chief operating officer of The Great Bull Run. And with 2,000 signed up for the Conyers, Georgia, event, Dickens expects 5,000 to 7,000 to run there in October.

The US events will last one day each, unlike the annual weeklong festival in Pamplona, when bull runs are held every morning. Author Ernest Hemingway wrote about the festival in the 1926 novel The Sun Also Rises, which helped it gain worldwide fame and attract spectators from around the globe.

Organizers acknowledge that the Great Bull Run is likely to start out on a smaller scale than its Spanish counterpart. But they note that other physically challenging activities such as extreme off-road runs and obstacle races have become increasingly popular in the US, and they see bull running as a natural follow-up.

"I think it's just a progression where we are becoming more and more active as a society," Dickens said. "There's this fitness craze that started with running. I think this is just an extension of all that, but making it more interesting to the general public."

Dozens of people are injured each year in the San Fermin festival at Pamplona, most by tripping and falling. Bulls have killed 15 people since record keeping began in 1924.

Last month in Spain, a University of Utah college student and an Australian woman were gored by bulls. During one run, participants and spectators screamed as a bull tossed a Spaniard to the ground and attacked him, with fellow runners trying to pull the animal away by its tail. The man was eventually dragged to safety.

Organizers of the US events plan to include several safety features, making them "quite different than the running of the bulls in Spain',' Dickens said.
