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. If you get knocked down, cover your head and stay down. Tempt fate and wear the traditional red kerchief. The hordes could block your view of a bull that may be headed your way. Sit in the stands and savor the adrenaline rush.
