Before the race, you will be given a flag belt, just like the game of flag football. These 3 flags represent your vital organs; Brains, Heart and Entrails. The Zombies are stationed along the race course trying to eat brains (capture your flags).
If you lose all your health flags, you are infected with the zombie virus, and zombies win.
The Zombie Run is an event that is designed for you to push yourself physically but in a fun way. Don't let the Zombie angle fool you, this is a real mud run.
