It was only a matter of time, as zombies became a cultural icon outside of just films, books, and videogames, that people started to take thier zombie love onto the streets, and as running challenges began to become more and more profitable and popular, that someone would combine the too. You've heard of 5ks, 10ks, marathons and half-marathons, and maybe you've even heard of Obstacle Races and Spartan Runs and the Tough Mudder challenges.
Sure, you can run, but will you look this fashionable in the apocalypse?
