An update on this: I have started putting together a rucking route so that I might train for this. From my front door I can walk to an impressive chain of staircases that ascend a steep hill (Bay Area, what can I say?). The views are glorious and it is partially shaded and open air. Nice. Recently, I tested out the following: walk to staircase, go up and down the staircase three times, walk back home. The route was 2.62 miles and had a cumulative elevation gain (and loss, because out-and-back) of just under 700 ft. It took ~1 hour and I was wearing my light backpack with a 5lb plate in it. It wasn't exactly easy (my cardio is pretty trash right now), but I wasn't exactly pushing it either: it was reconnaissance!black_son_of_gray wrote: ↑Mon Dec 30, 2024 3:20 pmThe fitness component intrigues me. There is one test: "Carry a 25 pound pack over a 4 mile distance with ~1300 ft elevation gain in one hour and 35 minutes."
Coarsely, each trip up the stairs adds ~140 ft of elevation in about 0.15 miles round trip, so in theory, I can test myself with a decent approximation of the route by walking to the staircases, going up and down them seven times, then heading back home. That gets the elevation roughly correct, although my route would be a little shorter. I don't think distance is the key variable here though: the workload of huffing 25 lbs up approximately 2300(!) stair steps in an hour and half is way more energy intensive than a flat mile.
This goal is looking more formidable now that I have a real sense of what it involves... Can you do stairs with a moderately heavy pack for 90 minutes?
This is part of the reason my cardio is trashblack_son_of_gray wrote: ↑Mon Dec 30, 2024 3:20 pmWriting:
Some of you know this, most don't -- I'm currently knee-deep in writing a novel. I spend a few hours working on it per day, and it has been a great experience so far. [...]
Anyway, a goal for this year is to finish it. [...]

I share a lot of writing-specific details of this journey with the forum's illustrious writing MMG, but I shall lay bare some details for the general population.
I started pursuing fiction writing in earnest (a little dabbling before...) about two years ago. That was when I started writing for a couple of hours a day, most days. I even spent real money to attend classes/workshop at a local writers consortium. On the whole, that was a great experience and provided some very useful insights. Worth it. Would I do it again? Maaaaybe.
To date I have written perhaps a dozen or so short stories of various lengths, a novella that doesn't end well (I'd like to revisit that), and now the novel I am working on. The novel is somewhere into ~draft 3, meaning it's very readable (or will be when the current draft is done in a few weeks), but it still needs a good spit polishing with another draft, maybe more.
A few thoughts/observations:
I would encourage those interested to give fiction writing a try*. It is deeply humbling. You think to yourself while reading a mediocre book, "This is rubbish--I could do so much better!" Oh, you can? I'd like to see your attempt. You think you know how people really interact/speak/behave, not just some cliched archetype? Show me. In many ways writing a novel is like marathon training. There are generally two motivations among the runners: 1) finishing, and 2) racing. The finishers are the NaNoWriMo types who derive satisfaction from having done the feat. "I buckled down and wrote a 50k word novel in a month!" The racers hear that and say, "Yes, but is it even readable? What you've done is write a 50k word 'shitty first draft'. Now the real work begins, which is revision. Anything less than a masterpiece, where your soul is utterly poured out on the page, is bullshit." Of course, both are right. It is an accomplishment, and writing something good takes so much more effort. Also, like marathon training, some are more innately gifted than others. But the biggest factor for most people, regardless of whatever linguistic edge you may or may not have, is simply time. The number of miles run.
The psychology of writing is peculiar. At least, for me it is. For background it is worthwhile to point out that, before starting to write fiction, I had a large amount of experience writing non-fiction (e.g. scientific journal articles, etc.). Fiction and non-fiction are different kinds of beasts, although some of the skills are transferable. Concision is transferable. Clarity of prose is transferable. The satisfaction of the read is... maybe not? What do I mean? I mean when I wrote a lot of non-fiction, sciency things, there is a very logic-driven, organized framework to the whole thing. It reads well when the blocks are put into place just so. After a lot of work on a manuscript, I could find a very pleasant sort of satisfaction with it...perhaps in the way that some people find something well-engineered. To this day, I find myself waaaay more critical of the writing in non-fiction works. I see little cracks in how something was laid out, a bit of sloppiness around the edges, and I almost consider it intellectual malpractice (god, I'm insufferable...I know). It's somewhat peculiar to me, then, that I am considerably less judgmental with a lot of fiction that I read. I think this is largely because I don't have a ideal form in mind when I read it...that or the goal of fiction doesn't seem so cut-in-stone the way it does with non-fiction. Sometimes the goal is crass, formulaic escapism. Sometimes the goal is absurdist or surreal. Sometimes the goal is 'cozy horror'. I may read something I don't particularly like or enjoy or understand in a story, and I usually cast it off as simply a difference in creative preferences. Over the last two years, I have experienced something with my fiction writing that I never have with my non-fiction: genuine enjoyment. It doesn't happen very often, mind you, but occasionally I am able to work a story (or part of a story) into shape, and I'll start reading it...and I just keep reading it because I'm enjoying it so much. (Of course, that doesn't mean anyone else finds it enjoyable.) Part of why I find this so interesting is because what is enjoyable in fiction is so often difficult to figure out. If it is all made up, and doesn't have an ideal goal or form to follow, why do some stretches of text just 'click' in my brain so well? To me, the craft is simply trying to figure this out, or find it when it happens. And there are macro versions of this as well...hours spent writing where I think to myself "this is amazing!" as I carve out some character arc or whatever, followed by the next day where I can't help but think how absolutely inane and boring everything I've written is. It's very interesting to observe this in your own thinking patterns. Thankfully, there is a 'me' that sits outside all of this whipsawing with a bucket of popcorn and finds it interesting to watch...
On expertise and becoming an expert. Like most people with a fancy degree, I am a card-carrying expert in something so niche and specific as to be essentially irrelevant when it comes to practical matters of living. A decade of specialized training and I am left with the ability to kick your ass in a single category of Jeopardy. (I'll do it too, ruthlessly: Look on my works, ye Mighty, and despair!) So it has been really interesting to observe myself progressing along in another skill. The thing about expertise is this: it is only rear-looking. You can't see what it is off in the distance. You don't know what it is as you approach it. It is only after you get there and mull around for a bit, realize that there is a group of others mulling around with you because you've all ended up in the same place (peers, in a way), can you look back and see the journey for what it was. With my fiction writing, all I know is this: I have put in perhaps 2,000+ hours of "butt-in-chair-hands-on-keyboard", and I have by this point read several dozen craft books. I have developed a depth of experience, therefore, to know what a writing practice looks like, what works for others (and for me), and I have an awareness (fairly confident) of most of the major theories/concepts/methodologies. I know I am getting better. I can read the difference for myself. I'm not exactly sure, though, where the destination is or how long it might take to get there. I have learned a very important thing, though: I am more than happy to write for up to 4-5 hours a day, every day of the week. This is more than most people seem to be able to handle, even many people serious about writing. I am not saying I'm better, just that I have discovered my manageable workload capacity. (Apparently, 'full time'.) Maybe this means I get there sooner, maybe not.
This is getting long, so I'll stop here.
*I encourage everyone to have any kind of writing practice. Good writing is good thinking (even if fiction). Practicing good writing, therefore...
