>>1295997I live at an elevation of 10,500 feet.
I hurt every time I come back from vacation, it takes me about a week to adjust after a week on the beach.
My elevation regularly kills a small number of locals and visitors every year. As far as exercising at this elevation goes, it's not really a great idea until you've acclimatized, which takes most people a couple weeks. It hurts coming here. It will make you feel pretty sick. If you're in great shape you should be able to power through it, but if you're in anything less than perfect health, rigorous exercise here can kill you.
