Expedition climbing, or mountaineering, is where you tackle the highest peaks on earth, all of which a situated in the Great Ranges. These mountaineering trips are not a week away but many weeks or even months. For example, to climb Everest will take around 60 days. They are mountains that you almost certainly will need to go with a guided company to handle the logistics while you handle yourself on every aspect of climbing, mountaineering and endurance.
Going into the great ranges will require a building of your previous climbing and mountaineering, especially winter, skills. Navigation in bad weather, moving together on a rope, use of ice axe and crampons on level and steep terrain, belay skills and the ability to read objective dangers.
At altitude everything becomes a lot harder as your brain is starved of oxygen so you will need these skills to be second nature to you even if you go with a large company with a good client:guide ratio- a guide can only help you so much.
Mountaineering at altitude is very taxing, both physical and even more so mentally. The weeks, or even months, have a massive impact on you.
The most important aspect will be to train your mind to deal with the hardships you will face. Going on smaller expeditions, the Alps are a great place for this, in order prepare yourself for those long days and reduced oxygen.
Go on plenty of long mountain day, in summer and winter, to build up your physical shape, pushing yourself hard to make you body work. Even when you can’t get out into the mountains make sure you do physical exercise that forces you to push through your mental barrier of ‘I can’t go on’
Finally, practise the skills you need while on the mountains. This will give you the chance to refine your skills while physically and mentally exhausted which you will be at altitude.
Do all this, for many months, and then you will be fit enough to climb even Everest.
