The 'Yo-Yo' Method of Climbing Everest
You don't just walk to the Mount Everest summit. You climb up and down several times to 'teach' your body to survive. This rotation strategy is the core of every Mount Everest expedition.
The first trip through the Icefall is to Camp 1. Climbers stay for a night or two and then return to Everest Base Camp. It is the first shock of high-altitude Everest trekking.
The second rotation takes climbers to the Lhotse Face and Camp 3 (7,100m). This is the hardest part of the Mount Everest expedition training, proving you can function above 7,000m.
After the rotations, climbers return to Base Camp (or even lower valleys) for a 'luxury' week of eating and resting before the final Mount Everest summit push.
Rotations are boring and exhausting, but they are the only way to safely stand on the Mount Everest summit. Trust the process of the expedition.
