Up until I hit my head, even with ataxia, I was having a blast on Whitney.
I drank 8oz of the costco bone broth the first two hours for 32 ounces.
At hour three a 16oz meal replacement shake of 50 grams protein, 50 carb and 20 grams fat as I was still trying to avoid the insulin spike. I had one more of those shakes on the summit.
From hour four until I ran out of fluids just above the Lone Pine lake sign I had about 8oz per 30-45 minutes from my camelback which was water with a 1/4 teaspoon of celtic sea salt per 16 ounces (a Victor Conte rehydration tip) and four nuun tabs in the two liter bladder. I also started in on the gels, gummy and gu packs giving me the simple carbs and electrolytes to fuel me the rest of the way, plus one 20oz gatorade.
The good about being "fat adapted", you use less carbs for fuel at sub-maximal effort. The bad about that is fat takes way more oxygen to turn to fuel than carbs and when the air is already thin that can hurt in the long run. That was why I helld off on the insulin spiking carbs as long as possible, then once starting, staying on them until the finish.
