GLC, I think you nailed one of the fundamental issues a lot of women have with running (and other activities that require a high energy expenditure): they don't eat enough. It's a struggle to figure out how much to eat to fuel running and reconcile that with whatever programming each of us has in our head (and even harder if one is trying to lose weight). I am very sensitive to trying to keep my weight at a maintenance level, but I will often not eat enough. I'm getting better about eating foods with good fat and not freaking out; for years I ate too little fat of any kind. And there is no doubt that I run much stronger when I've had several days of good, balanced eating. Most importantly, in the fall I discovered that I run really, really strong the day after moderate red wine consumption. It was not a one-time experience!
