“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.”

“They say that a few minutes each day of petting your dog can raise your serotonin levels.”

“I promise you, I’m done running. I’m still selfish, but only where you and Noah are concerned. I have years of spoiling to make up for and I plan to spend every day of my life making sure you both know how much I love you.”
