Is it possible to run a marathon in less than two hours?
This question along with a history of the attempts fill the pages of Ed Caesar's new book "Two Hours: The Quest to Run the Impossible Marathon."
Once thought of as impossible, now mere minutes separate an elite runner from the history books.
Can a person be mentally tough enough and physically strong enough to break this long standing record.
