>>17509995The climb itself can be done in a day by very experienced climbers, but he is probably gonna take a week from base camp to the summit, they usually go to base camp about 5000 meters up and wait for a couple days, then they climb to camp 2 and wait there for a day or two for their bodies to acclimate with the low levels of oxygen, usually they climb with oxygen masks past camp 2, they rest in camp 3 and wait for the weather to clear to attempt the summit which is about 700 meters above camp 3. I highly doubt he is gonna try to summit without an oxygen mask.
