This was one of the more inspirational stories to come out of the Games this year.  Deborah Cordner Carson was a DNF in 2011 as she could not overcome her fears of the ocean swim, which was the first event.  She had to have the worst sinking feeling when the first event announced for this years Games was a tri, starting with a 700m ocean swim.  What I love about this story is that despite being totally afraid of it, she did it.  And instead of a DNF this year, she fought all the way to the end, finishing 13th overall.
