I'm typing in the first three passages of preface of the book. So what is the break point in marathoner's mind and how they know the moment?

"There is a moment in every marathon referred to as the break point. It is the moment the race will be won - or lost. It is the moment one runner, or sometimes a group of runners, breaks away from the others in the field.

"Often the Japanese will run under control of mile after mile waiting for that exact moment," says Frank Shorter, "The time to make their break."

In December, 1971, Frank Shorter, a law student at the university of Florida, won the Fukuoka Marathon in Japan, One of the great races in the world over the classic marathon distance of 26 miles 385 yards. At Fukuoda, Frank ran 2:12:50.4, a time close to the Olympic record of 2:21:11, set by Ethiopia's Abebe Bikila in Tokyo in 1964. In that key Japanese race, Frank also defeated some of the top marathoners in the world: John Farrington of Australia, Jack Forster of New Zealand, Akio Usami of Japan.

HunHun, you apparently are a loser in Marathon, have you ever thought of making the "break point", or just after a YN?
