I love to run as well. For long,long
distances. I assume you are also aware of the other aspects of good health as well. Try to increase fluid intake by about 16oz/day for the next couple of months. Also remember to really pack your diet with yummy whole foods, grains, beans, olive oil, and foods high in healthy fats such avacados, walnuts, and sweet potatoes. Most important of all, you must,must, must try as hard as you can to get 8 hrs of sleep at night.
