Today I found myself with another tent-related challenge – setting up an altitude tent ‘over’ my bed in the comfort of central London. It wasn’t a very elegant process with poles, arms, mattresses and duvets flailing about. I admit it took about an hour longer than it should have and my flatmate did intervene and call me mad.... But I did it. On my own (referring to the instruction manual only after the 3rd unsuccessful attempt!)
The tent is made of a special grade nylon with 4 clear vinyl windows and a small ‘mesh’ roof for air exchange. My mattress fits inside of the tent and serves as the tent base. Next I add the goose-down duvet, the 400-threadcount bedding and decorative pillows… It looks like a sultan’s lair and my mind boggles with 'pick up line' potential!!
This ‘portable altitude training sleep system’ will help with the Cho Oyu pre-acclimatisation process by simulating sleeping at 3800m and maximizing the physiological benefits associated with altitude training while sleeping or resting. About 45 minutes before I go to bed I turn on the ‘hypoxicator’ (small machine about the size of a microwave or a small beer fridge) and set it to the desired altitude. The tube running from the machine into the tent then pumps in the air filtered to reduce its oxygen content.
I admit, I’d prefer training high in the Swiss Alps by day in a gorgeous chalet with a fantastic mountain view by night while eating cheese fondue and enjoying the positive effects of altitude but sometimes in life I’ve learned to make compromises….
