Some time ago, I read an opinion piece of how foolish it is to wait for New Year's Day to start a resolution. If a resolution is worth doing, it's probably worth doing NOW. Which makes a lot of sense, but of course having read that I developed a slight aversion to starting things on New Year's Day. But that makes just as little sense as only starting them on that day.
Anyway, I started keto today. My blood ketones were 0.2 this morning, but of course I didn't expect to be in ketosis that soon after a full day of essentially normal eating. I went on the last run of the week yesterday, finishing the year out with a cumulative full marathon in a week, but I got rather lost and stopped my run short of home instead of seriously exceeding 110% of the previous week's distance. I ate at a little local restaurant before coming home, and a fair amount if rice and arepas were still rolling around inside of me. I may well not even be well into ketosis tomorrow morning, despite having had zero carbs today. All in good time. Anyway, I started out the day at exactly 90kg; my goal is to stay on keto until I lose 10% of my body weight, then go in for a scan. I'm hoping to accomplish that goal within three months. I did find out that there are powdered versions of heavy cream and of butter available; coupled with powdered MCT oil, they could make a decent portable version of keto chow. Unfortunately, the powders are rather expensive, so it would have to be for occasional use only.
I found a great deal on craigslist for a small osprey running vest. On my way to go get it, I found myself walking by the local REI outlet. It sure is nice to be able to shop in physical reality; comparing the size of products, for example, is much easier in real life. I ended up getting a spare spigot for my water jugs and a replacement buckle for my larger osprey pack. The running vest ended up being suboptimal, but I expected that; for example, it has a flip-down case on the left strap for a smartphone or similar device, which ended up being too small for my phone (expected) but also ended up being removable (unexpected, and very nice). I may be able to make a better one.
Speaking of making gear, I think the best option for a fastpacking shelter setup is probably a poncho tarp and a good bivy sack. With a good quilt or sleeping bag, and all the necessary accessories (pegs, lines, groundsheet, etc), I should still be able to put together a decent setup for less than 2 kg. The poncho tarp has a lot of potential. I'm thinking about making a prototype out of tyvek, both to test the design and get some experience sewing. I want to give it a slight catenary curve, but still leave it able to use a normal straight-ridgeline pitch. I want to have the hood roll down and get fixed in place like the mouth of a drybag, to (hopefully) eliminate any dripping when used as a shelter. It would be great if one end, or even both, could have beaks when pitched, in order to allow for the use of a small stove. Of course, that brings up the issue of poles; should they be external, with the bivy hanging from the inside of the tarp? Or should the poles be under the tarp, reducing living space and restricting how low the tarp can be pitched? External seems the best, but the placement of internal tie points for the bivy sack will have to be done carefully to avoid chafing when the poncho is worn. Perhaps the same tie points can be used to keep the beak material inside while in "poncho mode".
When worn, I imagine the poncho first being placed on the head, and being draped over the pack. The flap out in front would be the wider of the sections, the "head" end of the shelter. It would ten be wrapped back around the body, and held in place possibly by a carabiner or other device connecting it at the back of the waist. Then, the flap hanging behind the user would be drawn forward, and held by a belt, another carabiner, etc. A few fasteners along the longer edges could allow the material to be fastened around the wrists for convenience; for example, a toggle on a short piece of elastic cord (to allow for size variations) could engage a tiedown loop. Anyway, there are a lot of options out there.
I also found some good resources for making sleeping bags and quilts. I wonder if I could wander around at goodwill and the like and get down-filled garments for a good enough price to warrant cutting them up for the down.
