Reality.

You know how sometimes, you're running along...feeling like a total bad-ass athlete.  Like you are totally rocking this workout.  Showin' it who's boss.  You are in it to win it today.  Running along thinking you look like Desiree Ficker or Amanda Lovato.....feeling pretty much like a triathlon rockstar.....

and then you run by a reflective surface and see the train wreck that is reality and wonder how it is that you are even able to continue to move in a forward direction with form that bad.  And whoa, girl back off the root beer floats already.

Ya, I hate it when that happens.
