My plan was to take in about 3200 calories/day. This worked well as I felt good the whole time, both for energy and gut happiness. I did lose about 8 pounds in five days, and I did need a steady supply of perpetuem to feel strong. Without a supply of water at any part of the hike I would have been unable to mixed the perpetuem, which would have lead to a crash. This almost happened getting to Garnet Lake.
I planned 8 servings of perpetuem per day x 260 calories/serving = 2080 calories/day. I used somewhat less than this.
I used 3 servings of recoverite (540 calories) at my afternoon rest and at the end of the day. This totals to 1080/day.
I also used fish oil caplets, which added another 100 calories.
I premixed both the recoverite and perpetuem with Emergen-C, Ibuprofen, glucosamine, conjointin, and endurolytes. Plus a little caffeine in the perpetuem. This made using these items automatic.
I'm very happy with the Hammer Nutrition product line (no they don't support me). In the future I will throw in a power bar or gel to add a little diversity to the diet, but the basic idea of a liquid diet on a hard, hot hike is very sound.
Thanks again, Mark
