Based on my limited observation of the ULers in my meetup group, they all tend to be type A, go go go types who not only go light, but go very fast. I have yet to meet a leisurely-paced ULer, though I am sure they exist. Our ULers always end up getting up earlier, leaving camp earlier, arriving earlier to the next campsite, etc., and can't be bothered with cooking hot meals, hanging out at the campfire, hiking with the group, etc.

If I were to lighten my load significantly, I am not sure I would be able to go any faster, or change how I cook, etc, but I bet I wouldn't be as worn out!
