I'm probably 10 pounds heavier thanI should be and I'm not fast by anyone's measurement. I make up for that by doing what others don't like to do - I use ALL of the hours in a day. All 24 of them. I've done some big day hikes, but I've been out there over 23 hours at a time. I was researching a hike to do in Sept when I have some vacation days - I was looking at the Rae Lakes Loop as a day hike. Sounds impressive, until I found a guy who did it in TWELEVE hours. Kinda makes doing it in 24 seem like no big deal. Damn skinny little ultra runners...............................DUG
