Challenge your concept of impossible. Meet Joel Runyon, he did. Laid off from his part-time UPS job and fed up with living in his parents basement, Joel decided to "start living a life worth writing about." Last summer, Joel joined Pencils of Promise's program The Impossible Ones. He took on a challenge that previously seemed impossible, to run an Ultra Marathon, 50k in one day, and raise $25,000 to build a Pencils for Promise school. Joel will run this weekend in Chicago.
