And for a perfect training of high altitude, I recommend yo to do by your own the trip through the south Engilchek from Maida-Dyr to Base camps of Khan Tengri a 50 km walk along one of the longest glacier in the world. I've doneit totally solo, it needs five days of walk, no particular alpine material, just good trekking choes. I could give you more detail and the entire precise map if you mail me to the following. email@example.com
It's a great experience to do it by your own, not so expensive, only to hire a 4x4 to Ak-Jailoo, then start the trek, It is possible to bring more alpine materials in the base camp arranging to bring them only by helico from Maida-Dyr, starting the trek from Ak Jailo, join the base camp in 5 days by the Engilchek glacier. Then getting the high altitude alpine material (send from the helico) and then directly start the normal route of Khan Tengri until camp III (5800). Then climb the Pic Petka 6120, and if you're on a great physical health, trying the Khan Tengri, but it is more difficult althougth there is fixed ropes on it, it's a hardest alpine target !
You can do exactly the same by your own on the Peak Lenin, but due to tragical events this year, I have change to the north area. I plan to return to Peak Lenin on summer 2012 with my wife and my little children
