" It was hard to understand, and all I knew was that you had to run, run, run without knowing why you were running, but on you went through fields you didn't understand and into woods that made you afraid, over hills without knowing you'd been up and down, and shooting across streams that would have cut the heart out of you had you fallen into them. And the winning post was no end to it, even though crowds might be cheering you in, because on you had to go before you got your breath back, and the only time you stopped really was when you tripped over a tree trunk and broke your neck or fell into a disused well and stayed dead in the darkness forever. "
