Sometimes I feel as if I'm racing with my own shadow, Korogi says. But that's one thing I'll never be able to outrun. Nobody can shake off their own shadow.

All I do is keep on running in my own cozy, homemade void, my own nostalgic silence. And this is a pretty wonderful thing. No matter what anybody else says.

Of course it was painful, and there were times when, emotionally, I just wanted to chuck it all. But pain seems to be a precondition for this kind of sport. If pain weren't involved, who in the world would ever go to the trouble of taking part in sports like the triathlon or the marathon, which demand such an investment of time and energy? It's precisely because of the pain, precisely because we want to overcome that pain, that we can get the feeling, through this process, of really being alive--or at least a partial sense of it. Your quality of experience is based not on standards such as time or ranking, but on finally awakening to an awareness of the fluidity within action itself.

Pain is inevitable. Suffering is optional.

The thoughts that occur to me while I’m running are like clouds in the sky. Clouds of all different sizes. They come and they go, while the sky remains the same sky always. The clouds are mere guests in the sky that pass away and vanish, leaving behind the sky.

For me, running is both exercise and a metaphor. Running day after day, piling up the races, bit by bit I raise the bar, and by clearing each level I elevate myself. At least that’s why I’ve put in the effort day after day: to raise my own level. I’m no great runner, by any means. I’m at an ordinary – or perhaps more like mediocre – level. But that’s not the point. The point is whether or not I improved over yesterday. In long-distance running the only opponent you have to beat is yourself, the way you used to be.
