I was at the turnstyle when a guy tried to sprint thru. I can guarentee you can outrun any of those security guards. The problem lies when you sprint thru and they yell for their buddies. You stick out like a sore thumb and they tackle you. If they get you it will hurt, i promise. A minimum wage human pylon's biggest thrill is to get to take out a runner.
You have a better chance finding a guard off to the side and bribing him. The problem with this year is they will probably kick you out withou8t a bracelet.
