If you are actually planning to run with the bulls, the first thing you should do is get a brain scan. People have gotten seriously injured. You are expected to outrun a scared and angry 1,200-pound bull. Have an escape plan. A quick dive under the rail will skin your knees, but you may escape serious injury.
Theft is rampant.
Remember that the run is one-way. Disastrous consequences can happen if a bull gets turned around and doubles back. Get past the one sharp curve. Bulls often slip on the cobble stones and panic. Keep your head on a swivel, looking behind you for the bulls coming up fast on your heels and forward to make sure some drunk hasn't fallen in your path.
