For more from my favorite blogger (myself included) go here. Start at the beginning, and prepare to be inspired.
If you're too busy to read it, let me leave you with a quote from my favorite entry:
"To say I fulfilled a lifetime dream would be a lie. But maybe that’s the beauty; I had just done something that I perceived to be so far from possible that I hadn’t even dreamt about it. 12 months ago I was locked in my bedroom killing virtual demons and eating pepperoni Hot Pockets. Today, I’m a marathoner" - Ben Davis
