Zombie Sprint, Tempe

Problem-solving skills. A bit of street smarts. Maybe a smartphone to look up facts or call a friend for help. These are all things a person might need to take down one of the terrifying monsters that stand in the way of the finish line at Zombie Sprint. The course seems straightforward enough: teams of two solve six clues and then make their way through hazard zones. But each of these zones has a zombie guarding the way—and these monsters are smart enough to operate a specialized gun that shoots food-grade "blood," marking racers with a zombie virus that will soon have them joining the undead horde.
