"Times for the marathon have been dropping since the distance of 26.2 miles was made official nearly one hundred years ago. But after a noticeable decline that occurred for half a century, the times ... have stalled several minutes north of two hours for the past decade ... [This] examines what it will take for an elite distance runner to go sub-two hours. It will require more than raw talent, optimal body size and great athletic genes ... The athlete who finally breaks distance running's most tantalizing barrier will become a worldwide celebrity overnight ... how soon will it happen?"--Publisher's description
