If you've never wanted to run a marathon before, watch this video. It's amazing. The film follows five runners - three amateur and two elite - as they prepare for the Chicago Marathon, which, being my first marathon, is near and dear to my heart. And legs.

Even though I think about having to run Nike in, oh, twenty-some days, and want to die, this reminded me of just how sweet it is to have accomplished such a feat. And to have the desire to do it again.
