The day before I did my Ironman, I bought a sticker that said "IronMan Finisher". I really liked the sticker and thought it would be cool on my car. Also, I figured it would be a little extra motivation to finish because I wouldn't dare put it on the car if it weren't true.
This morning I was parked at a local grocery store parking lot just about to get in my car and someone approached me. "Hey, did you really finish an Ironman?" I answered affirmatively. He then responded, "Wow, that's not trivial!"
