Everything Hurts

Ok, so you knew this has to happen. I am sore, stiff, tired, and I am wondering what in the world makes me think I can go 140.6 miles. Every once in a while I have doubts about my ability to finish. Last night at bootcamp I have everything I could do to pull a 45 pound weight off the ground and up 8 feet ten times, tonight I rode in our cycling class for 2 hours and I was shot, no run after just wanted to go home and crawl into bed. As I try and look at my defeatist attitude right now it probably has something to do with a long work week and the self doubts that I get when I am tired. It is easy for me to forget all of the successes that I have had to this point and all of the support, but I still have to wonder what is driving me. What is it that will drive me back and push me to work harder. Tomorrow is another day and I guess that I will find out then.
