Calling GaliWalker and anyone else who has trekked in the Himalaya and similar very high altitude regions. What did you do to prepare for the altitude? I feel like anything I can do is paltry: spend a few days up in the Sierra (fairly challenging at this time of year), or spend a lot of money on one of those low-oxygen tent things (I’m not going there). But I do worry about acclimatizing. We start hiking fairly low, just over 9000’, and don’t start sleeping high for most of a week, but even so, we’ll be going over some high passes every day (Sierra-type high in those first days). I know we’ll be okay on the first few days, because we’ve done that sort of thing, right up from sea level. But by the end of the first week we’ll be getting up to 15K and beyond, and I know one week is pretty minimal prep. So, the question: anyone have any tips, besides what’s mentioned above? And did you do anything special before your own trips to high altitudes? Thanks!

I confess that I didn't do anything special during my prep for any of my high altitude trips, other than work on fitness*. But I've been lucky enough to tolerate the altitude well, so far. While you're there though, here's what I would do: - Don't do too many big elevation jumps between each day's ending elevation. Going over a high pass, but then dropping down to camp is ideal!
- Think about adding a rest day or two, especially early on.
- Don't try and exert yourself or try and push hard on climbs. That can result in headaches.
- Spend 4hrs awake before going to bed. If you feel up to it, walk around camp and maybe climb something above camp, then come down.
- Stay hydrated! Drink lots of water. Have soup.
- Eat nuts and/or dried fruit.
- Avoid oily foods.
Enjoy the experience!
* By 'fitness' I mean cardio! (Obviously, we all work on leg strength and endurance anyway.) I did jump rope workouts, on top of the StairMaster stuff I already do.

GaliWalker, thanks for the recommendations! I’m not in charge of itinerary (going with an organized tour), but it looks like they have followed the advice about up, over, and down. We’re staying in lodges, which means villages, so that helps—they do tend to be in valleys, rather than atop passes! I hadn’t heard that about staying up 4 hours (presumably after hiking) before bed. Or do you mean after dinner? That would be challenging, I’m guessing, but after the hike it should be doable.

I hadn’t heard that about staying up 4 hours (presumably after hiking) before bed. The thinking is that almost all altitude problems happen when you're asleep, because the body has a tendency then to revert back to the last altitude it was used to. Spending 4hrs at your day's end elevation before going to sleep provides enough time for the body to adjust. I was provided this advice on my very first Karakorams trip, by not only my guide, my porters, but also by some Pakistan Army personal - liaison officers for climbing parties - that I had met. The Pakistan Army has a lot of high altitude experience, because they man posts in the region at over 20,000ft for months. To be clear: If you begin at elevation X, go over a pass X+Y, but then go back down to an elevation close to X, then you don't need to worry about staying up for 4hrs after you're done with the day's hike.
