Games require skill....

This was a Runner's World quote of the day a while back.....
Games require skill. Running requires endurance, character, pride, physical strength, and mental toughness. Running is a test, not a game. A test of faith, belief, will, and trust in one's self.  If you have to ask us why we run, you'll never understand, so just accept. ~Jessica Propst

People ask me why I would want to run 100 miles and I try to explain but ultimately end up where the quote does.  In my explanation I usually tell people it is a mental test of getting my brain and legs to do the same thing.  For most of us who do this, the brain is the weaker half of the equation.
