I'm an experienced hiker and most of my past experience has been steep elevation gains with a 40lb pack. Now I plan to thru hike a graded 70 miles trail starting Friday evening (after work) until Sunday (afternoon...evening) carrying a 3L reservoir pack, light sleeping bag, compass, map, knife, and a spare water bottle or two. There is water available every 12 miles via trailhead fountains so I'll refill at each stop. This is semi-arid, mountain lion, rattlesnake country. I'll be hiking alone. I figure 10-12 hour days, dawn to dusk, at 2.5-3mph should do the trick; jogging on flat and downward slopes. I have two concerns - 1. that a 3mph average cannot be achieved and I'll miss my pickup; 2. that hiking dawn to dusk, perhaps into the night (see #1), puts undue risk with a puma attack or rattlesnake activity.
Is this achievable?
