Half #17 in Jeopardy

Half-marathon number 17 is Sunday and I woke up today feeling like my head was going to explode.  I don't know if I will make it.  I was so looking forward to this half.  The course if flat.  I had a super-fast time last year (even though I couldn't keep up with the kiddie run happening at the finish), and I am ten pounds lighter than I was for the half two weeks ago.  I was super curious to see how that would impact my finishing time.  I am resting lots, taking different meds, drinking fluids, and somehow managing to sit through class this weekend and hoping for the best.  If half-marathon #17 doesn't happen on Sunday at least there is always the Super Bowl!
