Day 80...not so good

Well....today was a pretty bad run.  I went for a 20 min run but gave in and walked 2 times during the run.  I ran a little over 1.5 miles before I did, but none-the-less I gave in.  It wasn't even that I was tired or sore, it was just that I gave in and didn't have the self control to keep going.  I have got to work on that if I ever want to get to a place where I can run longer.  It's just so easy to fall into the trap of giving in and just walking.
