Oh man that race sounds really crazy. I can't believe they tried changing/correcting it mid-race when others had already finished. Congrats on running it well though! And that's awesome that your diet is working for you. I really don't do well trying to restrict myself with my eating. I find I eat healthiest when I eat what I want when I want, because for the most part I've learned that I enjoy "clean eating" (as defined by no white carbs or simple sugars). Anyway, you are totally right that our diets are very personal things, but I am always interested in hearing how other people do it!
