People think I'm crazy to put myself through such torture, though I would argue otherwise. Somewhere along the line we seem to have confused comfort with happiness... Dostoyevsky had it right: 'Suffering is the sole origin of consciousness.' Never are my senses more engaged than when the pain sets in. There is a magic in misery. Just ask any runner.

Adventure books are my personal favorites. 'The Endurance,' a story about Ernest Shackleton's legendary Antarctica expedition, or 'Into Thin Air,' Jon Krakauer's personal account of the 1996 disaster on Mt Everest, are two notables.

Pain is the body's way of ridding itself of weakness.

Running back-to-back races requires a certain tactical prudence. Going too hard in any one race might jeopardize your performance in another. Maintaining proper hydration and caloric equilibrium also becomes increasingly critical.
