Sorry, I never hit the wall when hiking. I am not out to cover ground, but wounder around leisurely and enjoy myself. When I was younger, I don't remember ever doing it either. Maybe I did, but either I didn't know it, or don't remember.

I usually take a few cliff bars just because of their high energy content per weight, also taste. <img src="/forums/images/graemlins/grin.gif" alt="" />

I don't usually overdo it and lose appetite. I walk too slow.

In basic training, I would drink 12 quarts a day when out in the field ( they made us, we had to keep a hydration card with us and mark each time we drank a quart. We had to drink one an hour). I went to Fort Benning in July. I easily sweated out those 12 quarts in the same amount of time. When I was in Iraq, I also easily drank 12 liters a day (they gave us water bottles of 1.5 liters).
