For all you guys dreaming of the Zombie Apocalypse Your chance is here to evade the walking dead. Here is a video of a very unique "Mud Run" concept allowing you to have that experience. Basically its a 5k mud run type event with obstacles and volunteers that act as Zombies. You have three flags that Zombies try to snatch while your running the course. They seem to have some pretty decent make-up artist to set the tone.
I'm thinking about doing the one this September in Atlanta.
