At 6000 feet of altitude people standing still are at risk from altitude sickness if they are not acclimatised as the amount of oxygen present in the air is down to 18% (it is 21% at sea level). Aaron & Lewis touched 12000 feet at some parts of the challenge where there is only 15% oxygen in the air.
