Picture this: On a sunny morning, hundreds of runners take their position at the starting line to run a marathon. At the blow of a whistle, they begin to sprint towards the finish line. It’s an exhilarating experience. Now, come December 17, and you can run a marathon via a mobile app Awarathon that tests your social alertness.
