My 2005 Marine Corps Marathon Medal. I think I'm going to carry this around in my pocket for the rest of my life to convince the doubters when I say I've run a marathon.
Of course, for the record, I didn't “run” the marathon, exactly. I mean, I ran and walked it and most of it was a run, but still, I kind of hope someday to be able to do 26 miles running the whole thing. For now, I'm glad of what I've done and I think I'm going to rest a bit before deciding what to do next (other than NaNoWriMo, that is).
