I, on the other hand, don't see the reliance on protein while foregoing fat (fuel). As it turns out, I am having a full panel later next week.
. I'm as curious as you.
As for "all that fat," i just note that some are advocating going with little or no fat for hours during fairly exertive activity. The body functions well by metabolizing fat up to a point - I have to sugar up after a out two hours. Fat is part of a healthy diet. Just wondering where it is on race day?
Lastly, on the subject of "carbo-loading," look all around your starting rows. See those bellies? Most of them have been carbo-loading for decades. It's called the modern American diet.
