My running is fun. Not ha-ha fun, but a quieter kind of contented fun. Not fun every minute of every day, but fun in the overall effect. My running is easy and comfortable, and it feels good. Seldom is there a morning when I don't feel 100 percent better in the last mile of a run than I had in the first mile. Never is there a day when I don't look forward to my run. Sometimes I don't want to go very far or fast, but I always want to go. Never is my running boring, because never are two runs exactly the same. They may be the same distance, at the same pace, over the same course at the same time of day. But they're subtly different. You learn to appreciate the subtleties.
