Keep Going!

"In the process of completely exhausting myself, I connect with an inner part of me ordinarily veiled by the everyday distractions of life. During that short time spent on a trail in the mountains, my life is reduced to its simplest terms. Most ultrarunners are people who find goodness and joy in difficult times, who see beyond the misery to the beauty of nature, and who truly realize the elemental and important aspects of life. Going for a run always clears my head, but running 100 miles distills my soul."
Keith Knipling

 

I think the above applies to distance runners too.
