Two hours to cover twenty-six miles and 385 yards. It is running’s Everest, a feat once seen as impossible for the human body. But now we can glimpse the mountaintop. The sub-two hour marathon will require an exceptional combination of speed, mental strength, and endurance. In this episode, award winning journalist, Ed Caesar is sharing a section of his fascinating book: Two Hours – The Quest to Run the Impossible Marathon. 

Ed traces the history of the marathon as well as the science, physiology, and psychology involved in running so fast for so long. And he shows us why this most democratic of races retains its brutal, enthralling appeal—and why we are drawn to test ourselves to the limit.
