Looking for some thoughts and feedback for my tentative gear list for my planned attempt at the unsupported speed record for the Colorado Trail this summer.
Some background as to my plan. I am looking at starting the middle of August for a few reasons. That is when my work schedule allows, snow pack will not be an issue, thunderstorms will be less (hopefully) and mosquitoes will be gone. (I HATE mosquitoes!). I know by going then I will lose a bit of daylight and water will be slightly more scarce. Tradeoffs I am willing to make. I am planning on carrying 13 days of food (32.5lb) at roughly 2.5lbs per day with 4800-5000 calories. I will hike for 18-19hr a day with 16 of those moving. That will leave 2-3hours per night hiking in the dark, with another 1-2 hours in the morning before dawn. I'm expecting over night temps to be 25-35 degrees depending on elevation. I'm trying to balance going absolutely as light as I can, while ensuring that I can get adequate sleep at night (re: comfort). I will cook one hot meal per day for morale boosting and see the weight benefits of carrying a cook set for this extended carry.
Things I'm considering.
– I know my electronics are fairly heavy. The SPOT is needed for verification and I will need two sets of batteries. I'm looking at my headlamp choice. I think it is valuable to have sufficient light at night to see (avoid injury), but am debating whether I want to carry two different types of batteries (CR123 & AA). I know I could ditch the Petzl, but for .75oz its probably lighter in the long run in not having to carry an extra battery. Music is a must. Know any great MP3 players with 16g+ and loooong battery life?
– I'm wondering about how the Klymit pad and quilt will fair? I'm worried that the gaps in the pad will leave drafts all night with the bottomless quilt. I may take a small 24"x12" piece of 1/8"EVA foam. Any body have experience with a similar set up. I will be doing some overnight trips the end of the month to try out the combo.
Any thoughts would be much appreciated. See my tentative gear list posted under my profile.
