I carry 1.4 lbs of very calorie dense foods per day and consider that about as good as I will get. I typically carry 6 days or more of food at the start of each leg. I have carried as much as 10. I do not find it convenient to visit every town for resupplies. 6 days of food is 8.4 lbs. I often carry 4 pounds of water. Now I am up to 12.4 lbs before I even think of gear. Hmmmm.....
Non hikers are about a psi shy of a legal ball.
