Today I was running for a while in Central Park. It’s nice to run when all of the Olympic athletes aren’t out in fancy running gear, lapping you, while their hearts thump along at a chill 65 bpm.
But anyway, if you aren’t an Olympic athlete, I think you have to put a decent amount of mental focus into running. I can’t really focus on anything moderately complex when running. The good news is you’re boosting your cardiovascular system and improving muscle tone. And your exercise goes by faster.
In comparison, if I walk, I can have a more interesting mental dialogue. This is a great time to put your thoughts in perspective, and look at things from a different angle without all the contextual clutter of your usual workspace. For me, this usually includes rethinking some technical challenge or general strategy. It’s not always work — maybe it includes time to think of what birthday presents I should get for others, or who I need to send a thank-you card to or get in touch with. But the point is, I’m always surprised by the number of important ideas that emerge when I’m just walking. This is, I think, more valuable than a little added muscle tone.

I think the most advantageous strategy is to run first. Run until you get a second wind and your legs start feel different, maybe a little numb. And your field of vision is narrowed by about 15 degrees. Then, with your senses partially numbed, walk home and divert all of your energy to your thoughts. If you’ve got an MP3 player, either shut it off or play some song you’ve already heard a billion times. That way you’ll ignore it. Make sure your field of vision expanded again, that means your brain has the right amount of oxygen. Take a few breaths, and think like you’ve never thought before.
