The zombie theme has been played out on the big and little screen, but put zombies on a mud run and it is an entirely refreshing and terrifying experience. There is nothing like being chased by a zombie hoard to really push you to excel. And if you don’t want to run, you can always sign up to be one of the zombies. You can choose one of the 30 minute time slots between 8 am and 4:30 pm. The race is coming to both Dallas and Austin.
