I'll be happy if running and I can grow old together.

No matter what, though, I keep up my running. Running every day is a kind of lifeline for me, so I'm not going to lay off or quit just because I'm busy. If I used being busy as an excuse not to run, I'd never run again. I have only a few reasons to keep on running, and a truckload of them to quit. All I can do is keep those few reasons nicely polished.

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.

Even if there were two of me, I still couldn't do all that has to be done. No matter what, though, I keep up my running.

When you see runners in town is easy to distinguish beginners from veterans. The ones panting are beginners; the ones with quiet, measured breathing are the veterans. Their hearts, lost in thought, slowly tick away time. When we pass each other on the road, we listen to the rhythm of each other's breathing, and sense the way the other person is ticking away the moments.

The last time I ran a full marathon it was awful. I've run a lot of races, but never one that ended up so badly. There are three reasons I failed. Not enough training. Not enough training. And not enough training. That's it in a word. Without knowing it, I'd developed a sort of arrogant attitude, convinced that just a fair-to-middling amount of training was enough for me to do a good job. It's pretty thin, the wall separating healthy confidence and unhealthy pride. As I ran this race I felt I never, ever wanted to go through that again. Right then and there I decided that before my next marathon I was going to go back to the basics, start from scratch, and do the very best I could. Train meticulously and rediscover what I was physically capable of. Nobody's going to win all the time. On the highway of life you can't always be in the fast lane. Still, I certainly don't want to keep making the same mistakes over and over. Best to learn from my mistakes and put that lesson into practice the next time around.

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.

Pain is inevitable. Suffering is optional.
