We've got a motto here-you're tougher than you think you are, and you can do more than you think you can.

Distance running was revered because it was indispensable; it was the way we survived and thrived and spread across the planet. You ran to eat and to avoid being eaten; you ran to find a mate and impress her, and with her you ran off to start a new life together. You had to love running, or you wouldn't live to love anything else. And like everything else we love-everything we sentimentally call our 'passions' and 'desires'-it's really an encoded ancestral necessity. We were born to run; we were born because we run.

You've got enough fat stored to run to California, so the more you train your body to burn fat instead of sugar, the longer your limited sugar tank is going to last." -The way to activate your fat-burning furnace is by staying below your aerobic threshold--your hard-breathing point--during your endurance runs.

Try the meditation of the trail, just walk along looking at the trail at your feet and don't look about and just fall into a trance as the ground zips by," Kerouac wrote. "Trails are like that: you're floating along in a Shakespearean Arden paradise and expect to see nymphs and fluteboys, then suddenly you're struggling in a hot broiling sun of hell in dust and nettles and poison oak... just like life.
