Eliud Kipchoge Breaks Two-Hour Marathon Barrier

In Vienna, the Kenyan achieved a milestone once believed to be unattainable. But his time, 1:59:40, will not be recognized as a world record.

In becoming the first person to cover the marathon distance in less than two hours, Kipchoge, 34, achieved a sports milestone granted almost mythical status in the running world, breaking through a temporal barrier that many would have deemed untouchable only a few years ago.
