“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. Respecting that speed limit was a lot easier before the birth of cushioned shoes and paved roads; diet, and those tumors may never appear in the first place. Eat like a poor person, as Coach Joe Vigil likes to say, and you'll only see your doctor on the golf course.”
