In a zombie apocalypse, there are usually just two camps: the living and the undead. But not all zombies are alike at Lake Eerie Zombie Mud Run: some run, some lunge, and some appear out of nowhere. The ghouls chase the 5K's runners, who navigate a muddy route full of obstacles that challenge endurance and nimbleness. If zombies take all their flags, runners have the chance to win an extra lifeline by completing an additional obstacle at one of the run's vaccination stations. Otherwise, they cross the finish line infected. Regardless of their fate, all racers receive entry to the post-run survivor's party, as do all spectators, who can cheer their favorite participants on from zombie-proof viewing areas.
