A new zombie horde rises, hungry for the packs of humans that flee in a desperate fight to see another day. This isn't a vision of a postapocalyptic future—it happens every fall at the Zombie Run Challenge, an event in which participants dressed as zombies chase down human competitors in a race for both survival and top prizes. After registering, competitors separate into the two factions, each with separate goals. In the course of up to two hours, zombies attempt to turn humans by capturing the flags attached to their belts. The living, in turn, try to complete challenges at four–five checkpoints, taking momentary refuge or healing at outposts scattered throughout the woods. All the while, a group of volunteer mercenaries armed with foam darts hunts down the undead attackers. Before the race begins, the special-effects gurus at Gregory F/X will provide zombie makeup to participants in exchange for a donation—100% of which goes to charity and won't be used to buy the zombies fresh brains at the local deli.
