Your diet seems pretty healthy from what you posted.I noticed that in your diary posts there are not many protiens listed. You do have milk, yoget and turkey listed, but all are easily digestable and do not give sustained energy. I would agree with PotentialPhreak about complex carbohydrates, whole wheat and multi-grain type foods during your meals (B,L,D). But one thing that I would personally suggest, especially since you are not wanting to loose the weight, would be more protiens through out your day. Milk, yogert and turkey are good to eat, I would just ad more of them in and possibly ad more type of protiens. It is usually good to get them from more than just a few types of foods as each type of food offers specific types of protiens. Try adding in pieces of chicken and fish, plus goats milk if you can find it anywhere, just to change things up a bit.
My other suggestion would be a good multi-vitamin that is high in the B's and iron. With the diet you have posted it and running as much as you are, you could easily be buring off all of you b's and the body uses iron to transport oxygen (low oxygen low energy).
Something like TwinLabs amino fuel may be beneficial. It is high in B's and quite a few highly digestable and muscle targeted amino-protiens. This could be a good suppliment before your run using about 1-2 tbsp. I started using 3 tbsp starting about 3 weeks ago, and when taken with about a glass of water 5-10 min before my workout I have a huge energy boost that lasts for about 1-2 hrs depending on my routine that day.
Post running, try eating foods high in potasium. Muscle growth, fast or slow twitch, comes from strenuous excercise causing small tears that the body replaces with newer, stronger muscle. Potasium helps the body heal and recover faster and more efficiently. Foods like a banana, 1 cup of antelope, a few figs, a cup of milk, or a half cup of OJ or Tomato juice.
More dark green vegetables. I'm not sure what kind of lettuce you are having in your salad's, but stay away from iceberg, it has not redeeming health value other than fiber. Try to eat romaine or red lettuce and spinach in your salads.
And final suggestion
by Dr Ted Broer can give you quite a few tips
I have some other suggestions, but I don't want to overwhelm too terribly much (if i haven't already)
