How many bulls are in the Bull Run?

In total, you will see 12 animals. There are six bulls which can be identified immediately by their darker coloring, either black or brown. The other six bulls are actually steers, recognizable by their lighter coloring, usually white and brown spots. Up close you can also tell them apart because the bulls are not castrated. The purpose of the steers is to keep the whole pack together and to calm down the bulls. The steers run every day and know the course well. Steers are harmless, meaning they will not try to gore you. If you stand in their way, however, they may bump into you.
