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. The pioneer will have to endure more, live braver, plan better, and be luckier than anyone who has run before. So who will it be? In this spellbinding book, journalist Ed Caesar takes us into the world of elite marathoners: some of the greatest runners on earth. Through the stories of these rich characters, like Kenyan Geoffrey Mutai, around whom the narrative is built, Caesar 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. is a book about a beautiful sport few people understand. It takes us from big-money races in the United States and Europe to remote villages in Kenya. It’s about talent, heroism, and refusing to accept defeat. It is a book about running that is about much more than running. It is a human drama like no other.
