I couldn't really figure out what happened. I have often felt tired or sore, but not heavy legs that can barely move. What had I done wrong/differently? After thinking about it a little, I remembered that I didn't eat dinner the night before. I was really tired and not hungry so I went to bed early and didn't eat. Hmmm. I probably didn't have any fuel to draw from. I also have a little bit of Mt. Dew in the morning and I didn't have that either. Good lesson to learn. Eat dinner the night before a long run!
I'm not sure how this 1/2 marathon thing is going to go. I haven't done a run longer than 8 miles. There isn't much time left. Maybe November will have to be the first 1/2 marathon instead of October. We'll see.
Do you have any nutrition advice for long runs?
