7 years ago Sergey, a 33 year old successful manager and entrepreneur, ran to catch a bus and got so out of breath that he almost fainted.
When he got back to normal a question got stuck in his head: what are all his achievements worth if he can’t even run 200 meters? That same day he realised he should change something in life. But to do that he needed a real goal, something significant and heroic. So he decided he should run a marathon.
