I live in Texas at water level so training for altitude is still a question mark for me. My main way of preparing is 30 lbs in my day pack and fast packing on a hike/bike trail close to our house. My typical hike is 5-8 miles at about a 14:20 pace, 3 times a week. I also intersperse mountain biking, resistance training, etc. This seems to work for me.
I should mention that carrying a weighted pack in an urban neighborhood is also a recipe to get laughed at by all the soccer moms dressed head to toe in designer spandex while talking on the phone and moving at a glacial pace.
