CitySolve Urban Race lets citizens explore their metropolis through a one-day odyssey that tests speed, stamina, and smarts. Teams scamper through their burb as they solve clues ranging from anagrams and pop-culture trivia to deciphering graffiti written in pig Latin. Interspersed throughout the race are mettle-testing physical challenges, molding iron wills to such tasks as dodgeball, improv comedy games, or identifying ice-cream flavors. Each day's race also awards winners for best costumes and best tweet. Each urban iditarod takes between two to three hours, and jet packs are strictly prohibited.
