I keep saying I'm going to pick up some Hammer Nutrition and try it out, but I keep spending my money on new gear instead. I will try the Hammer stuff, though. Too many people have recommended it to ignore it.
Christopher — I will probably be hiking an hour or two in the dark each day. I'd love to do 45-50 miles the first two days to give myself a shorter day on the third. This would make for a much more enjoyable finish and put me on top of the mountain at the end of the trail in time for sunset.
If I can manage a few more hours in the dark, I just might go for it. The thing is, I've heard that the hours spent on your feet take more of a toll than how fast you go. I think I can work up to 14 hours at 3 MPH, but 20+ hours, even if I go a bit slower, seems pretty daunting.
That said, I have no idea what my body will be capable of when I try this out in a few months. I'm doing an overnight trip next Monday and Tuesday and am just going to hike one way until I can't go much further on Monday, and then hike back that same distance on Tuesday.
Despite my intense training these last couple of months, I have yet to hike a 25+ mile day, so I'm interested to see how this goes. Hopefully I'll do at least 30 miles each day. Either way, the trip will give me a good gauge for the work I need to do to get in shape for this.
Right now, my gear list is still a bit heavy, so that will probably slow me just a bit. I'll be taking a Tarptent on next week's trip, since I haven't been able to get a lighter shelter yet. This is also going to be my first trip using Micropur tabs, so I'm sure lack of technique will cause me to carry more water than I need.
I did just pick up a short Ridgerest, though. It's too cold out to try a 1/8" pad, but I plan to pick one of those up later this spring and try it out as well.
