Can I?

Another week of training.  It was actually fun and easy until today.  I ran 12 miles in 2:09.  Coach Jeff wanted me to go faster but it just didn't happen.  I did keep my heart rate just under 160 bpm.  And then I started wondering if I could really do a marathon.  Doubts invaded my head at the finish of mile 12 as I realized I wasn't even at half way for the real race.  I drove home wondering if I was crazy and as I limped up the two steps into the house I figured I was dillusional.  I was tired, needed a nap and was cranky.  Bob went to work.  I was wondering where my support team was.  Negative thoughts were ricocheting, my body was moaning.  What did I do?  I got online and registered for the Honolulu Marathon, Dec 9, 2012.  I guess that makes it official and me totally crazy.
