Unless I'm missing something, you didn't mention where you're going or what you're doing? How heavy is your loaded pack?

Your training sounds very intense, at least to me, but then I'm leaning toward the elderly side of life. However, by any measure, 5,680 feet of gain and loss in 4 out of 8 days seems like a heck of a lot.

Something you must be careful of if you train too hard, expecially in a short period of time, is that you heighten the risk of injury. With your schedule and depending on your age you might not have time to recover.

At any rate, given that today is the 11th you're all ready in the middle of it. Hope it's working out for you!
