Also good for folks to realize base camp is at 17k feet and you typically go up to 4 higher levels of camp over the course of a few days. You aren't climbing 0 to 29k feet in one day--at most it's more like 4-5k feet in one day.
How is that “good for folks to realize”? No one is taking this challenge as an analog to climbing Everest. People are not out packing their bags to go to Everest after having done this.
The challenge is literally called "everesting". Your brain is working in a weird way if you're trying to claim there is no analogy or parallel being drawn here to climbing Mt. Everest.
The point being made, which in your fury you seem to be completely missing, is that climbing Mt. Everest is actually _easier_ than this everesting challenge. A guided climb of Mt. Everest would have you doing no more than about 5k feet of elevation gain in a single day. Over the course of a week you would work up to acclimating and preparing for the summit push. This challenge has you doing 29k feet of elevation gain in a single day--even at sea level and on a bike that is a tremendous leap in athletic challenge.
