Feeling a little bit better

I managed to get in close to 9 miles today in with 2 runs. I didnt feel spectacular on either of the runs but I at least felt better than yesterdays run.
Ive been looking a lot into nutrition for distance runners and I am starting to think that my recent problem has had to do with not getting enough food. I have been eating a good enough amount of food but apparently i should be getting in 700g of Carbs and 120g of Protein; I cant say for sure that I have been taking in that much.
Looking back whenever I have been running around 70 miles in the past, I always had either the dining hall at school or a dining hall at running camp. Now when I eat breakfast, I will eat cereal and a muffin. Thats not that bad but when I was eating at school I would have cereal, eggs, and other things on top of that.
So the next step for me is to make sure I am crushing at least two meals a day from now on. We will see how this new strategy pans out.
