Mobathlon is a mobile promotional campaign of NIKE ZOOM to complement ZOOM's new brand outlook, "Quick is Deadly."It's a Nike original sport event that transforms the everyday action of answering a mobile phone into a fun game. The rule is simple, to beat others' answering time. Anybody, anywhere with a mobile phone can participate. Then Nike calls you up unexpectedly during the competition. All you have to do is to answer it asap! When you get on the phone, the interactive voice message system reads out your record and current rank.
