What do YOU listen to as you run? Do you... think about your day, plan out what you're going to do? Do you... problem solve, teasing out work or personal problems in your head until resolution? Do you... zone out, either by listening to music or through the zen cadence of the run?
Me, none of the above. Without fail, about a quarter of the way into the run, I'll get a song in my head and it will stay there for miles. Often only the chorus. Common offenders: Eye of the Tiger (cliche, but effective), Single Ladies (Beyonce), Piano Man (Billy Joel), almost anything by Jim Croce. Recently it was She-Wolf, by Shakira. Over and over again, for probably half of my run. And I only know the chorus of the song.
On I went, out of the wood, passing the man leading without knowing I was going to do so. Flip-flap, flip-flap, jog-trot, jog-trot, curnchslap-crunchslap, across the middle of a broad field again, rhythmically running in my greyhound effortless fashion, knowing I had won the race though it wasn't half over, won it if I wanted it, could go on for ten or fifteen or twenty miles if I had to and drop dead at the finish of it, which would be the same, in the end, as living an honest life like the governor wanted me to. -Alan Sillitoe, "Loneliness of the Long Distance Runner"
