On the Zombie Run map, you basically have to run away from the crowds of zombies through narrow streets and through various buildings. You can’t stop, because in this case the living dead will immediately overtake you. On the map there are rooms with other survivors where you can relax, as well as checkpoints that will help maintain progress.
