I'm late to jump on the Born to Run bandwagon but I found the book surprisingly inspiring.
Ask nothing from your running, in other words, and you'll get more than you ever imagined.
Instead of cringing from fatigue, you embrace it. You refuse to let it go. You get to know it so well you're not afraid of it anymore.
Make friends with pain and you will never be alone.
It's a great book. Even if you don't run, I think you'll find it a solid read. And yes, I am going for a run tonight.
