Most mountaineering is not an adrenaline fueled pursuit and many adrenaline junkies would find it’s often non-technical tactics boring. Is it an egotistical pursuit? Sure. Objectively hazardous? Yes. But distance cyclists and runners have more in common with mountaineers than base jumpers.
There’s class 4 mountaineers, and WI6 mountaineers. It’s often hard to tell where any one person falls on that continuum.
