Halfway through a 45-minute run, I was thinking about a far-off friend and the bane of long-distance relationships. As I traced a well-known route through downtown Portland, Oregon, I wondered if the relationship could ever work out. And suddenly, practically from one step to the next, I had the idea for a science fiction story about a space pilot's lover, whiling away the centuries in suspended animation until the pilot returned from the stars. I raced home to write the story.

I'm not the first writer to lubricate the creative process with exercise. Narnia author C.S. Lewis was fond of long, contemplative walks. Most mornings, Stephen King runs several miles. And fitness buffs of all professions have long known that the best way to unlock creativity is to go for a bike ride, run or swim.Now science is proving that eureka moments during exercise are more than mere anecdote. Stephen Ramocki, a marketing professor at Rhode Island College, found that a single aerobic workout is enough to kick the brains of college students into higher gear—and that the benefit lasts at least a couple of hours. To function optimally, each person's brain needs a physically fit body, Ramocki believes.

Poll a group of runners and you'll find that on-the-move insights are so common that most athletes take them for granted. But it's disconcerting to know that you're likely to be miles from the office when insight strikes. Fred Lebow, founder of the New York City Marathon, once told an interviewer that whenever a great idea came during a run, he'd grab a twig and scratch it in the Central Park dirt. He'd go back later to recover his notes.

Creativity tends to be the result of a two-stage process, says R. Keith Sawyer, a psychologist at Washington University in St. Louis. The first stage is data gathering. That's when you're working hard to bone up on background material that you'll need to solve your problem. But the moment of insight tends to come when, having worked hard, you take time off for a change of pace.

Perhaps that's because during the preparation stage, the mind is so narrowly focused that it ignores random-seeming associations percolating in the subconscious. Yet creativity is, by definition, the process of making unexpected leaps.

When you're deliberately working on a problem, such thoughts seem like distractions, so you tune them out. To free up the mind, Sawyer says, creative people tend to schedule "idle time" in which to do something completely different—such as listening to music or taking a bike ride.
