Carlsbad Half Marathon 2012 Crunch Time

It's the final stretch to the Carlsbad Half Marathon.  This is my second half marathon.  So when do the butterflys go away?  After the 3rd or 4th half marathons?  I would like to say I'm no longer worried about finishing, but anything can happen! For my first half marathon, I peed about 4 times before the race.  Thank goodness for all the porta-potties.  This Saturday, the morning of my long run, I woke up with gastritis.  I did go for my run and finished my target miles, but I should have went back to bed.  I'm still trying to learn when to just say "it's okay, take the day off" and listen to my body. It's a working progress.
