"In a race, the ambitious contestant will want to stay fairly close to the leaders. He should be careful not to kill himself off at the start. He should let somebody else lead if the course is wet or the wind is blowing against him, and should watch the ground for good footing and keep a wary eye on his opponents to prevent being spiked or boxed. However, if the pace is too slow, he will want to take the lead. When fatigue strikes, the runner will want to call upon all his pluck. He must forget weariness by thinking of form and concentrating upon running as effortlessly and relaxed as possible. When the pace whips up at the start of the last half-mile, he remembers that he can always go a little farther and faster than he thinks he can. Mental fatigue comes before physical fatigue; in fact more races are lost through inability to resist mental fatigue than for any other reason. How many times have you heard a defeated runner ruefully exclaim after a race; "I could have run faster. I just didn't put out. I didn't know I had so much strength left.""
