Over at The New Yorker, Ferris Jabr explains why walking helps us think:

Because we don’t have to devote much conscious effort to the act of walking, our attention is free to wander—to overlay the world before us with a parade of images from the mind’s theatre. This is precisely the kind of mental state that studies have linked to innovative ideas and strokes of insight. Earlier this year, Marily Oppezzo and Daniel Schwartz of Stanford published what is likely the first set of studies that directly measure the way walking changes creativity in the moment. They got the idea for the studies while on a walk. “My doctoral advisor had the habit of going for walks with his students to brainstorm,” Oppezzo says of Schwartz. “One day we got kind of meta.”

As a former New Yorker, I walked everywhere for photo-shooting, idea generation, and because sometimes it’s the easiest way to get to where you’re going.
