Event organizers are gathering the help of U.S. ranchers and veterinarians to bring a tradition originating in 14th century Spain to Houston, Atlanta and Petersburg, Va.

The Great Bull Run, modeled after the running of the bulls at the San Fermin festival in Pamplona, Spain, will challenge runners in a 5k as they are chased by bulls. The traveling event offers a similar experience to the trip to Spain, without the additional expenses of traveling to Europe.

Event organizers are minimizing the risk of injury by partnering with ranches to provide the bulls and veterinarians to monitor animal health.
