“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.”

“No matter how much long-distance running might suit me, of course there are days when I feel kind of lethargic and don’t want to run. Actually, it happens a lot. On days like that, I try to think of all kinds of plausible excuses to slough it off. Once, I interviewed the Olympic running Toshihiko Seko, just after he retired from running and became manager of the S&B company team. I asked him, “Does a runner at your level ever feel like you’d rather not run today, like you don’t want to run and would rather just sleep in?” He stared at me and then, in a voice that made it abundantly clear how stupid he thought the question was, replied, “Of course. All the time!”

“People sometimes sneer at those who run every day, claiming they’ll go to any length to live longer. But I don’t think that’s the reason most people run. Most runners run not because they want to live longer, but because they want to live life to the fullest. If you’re going to while away the years, it’s far better to live them with clear goals and fully alive than in a fog, and I believe running helps you do that. Exerting yourself to the fullest within your individual limits: that’s the essence of running, and a metaphor for life—and for me, for writing as well. I believe many runners would agree.”

“Sometimes I run fast when I feel like it, but if I increase the pace I shorten the amount of time I run, the point being to let the exhilaration I feel at the end of each run carry over to the next day. This is the same sort of tack I find necessary when writing a novel. I stop every day right at the point where I feel I can write more. Do that, and the next day's work goes surprisingly smoothly. I think Ernest Hemingway did something like that. To keep on going, you have to keep up the rhythm. This is the important thing for long-term projects. Once you set the pace, the rest will follow. The problem is getting the flywheel to spin at a set speed-and to get to that point takes as much concentration and effort as you can manage.”

“I’m the kind of person who likes to be by himself. To put a finer point on it, I’m the type of person who doesn’t find it painful to be alone. I find spending an hour or two every day running alone, not speaking to anyone, as well as four or five hours alone at my desk, to be neither difficult nor boring. I’ve had this tendency ever since I was young, when, given a choice, I much preferred reading books on my own or concentrating on listening to music over being with someone else. I could always think of things to do by myself.”

“SO THAT’S MY LIFE—or my life before I stopped sleeping—each day pretty much a repetition of the one before. I used to keep a diary, but if I forgot for two or three days, I’d lose track of what had happened on which day. Yesterday could have been the day before yesterday, or vice versa. I’d sometimes wonder what kind of life this was. Which is not to say that I found it empty. I was—very simply—amazed. At the lack of demarcation between the days. At the fact that I was part of such a life, a life that had swallowed me up so completely. At the fact that my demarcation between the days. At the fact that I was part of such a life, a life that had swallowed me up so completely.”

“I didn't start running because somebody asked me to become a runner. Just like I didn't become a novelist because someone asked me to. One day, out of the blue, I wanted to write a novel. And one day, out of the blue, I started to run-simply because I wanted to. I've always done whatever I felt like doing in life. People may try to stop me, and convince me I'm wrong, but I won't change.”
