That's crazy run volume.
I am not surprised at all your body reacted "backwards" to increased food consumption. You just corrected some nutritional deficiency that was screwing with your cellular machinery.
You need to eat a very large amount…
very roughly:
100mile x 110kcal/mile = 11,000
100mile x 40kcal/mile = 4,000
BMR 2100 x 7 = 14,700
~4240kcal/day… that is some serious eating.
