His most inspiring entry is about The Blerch:
Marathon runners often describe a phenomenon known as “hitting the wall.” They refer to ‘the wall” as the point in a race when they feel physically and emotionally defeated.
I do not believe in the wall. I believe in The Blerch. The Blerch is a fat little cherub who follows me when I run. He is a wretched, lazy beast. He tells me to slow down, to walk, to quit.
“Blerch” is the sound food makes when it is squeezed from a tube. “Blerch” is the shape of my tummy after a huge meal. If I am sedentary at a time when I have zero excuse for being sedentary, I call this “blerching.” The Blerch represents all forms of gluttony, apathy, and indifference that plague my life.
A wall is an obstinate, immovable object. You cannot silence it. You cannot outrun it and you cannot beat it. The Blerch, however, can be outrun. He can be silenced.
I run because it’s the only way I know how to quiet the monster. I run because, deep down, I AM The Blerch.
He goes on to talk about how running has affected his life for the positive and you should really read the entire comic. It’s brilliant!
