My family and I were in Zermatt this summer. I climbed the Mettelhorn (no, not the Matterhorn) from Zermatt. The climb took four hours and covered 2000 meters. Even though I didn’t train in a structured way this year, I suppose that my endurance has increased due to consistent (if unstructured) effort.
Some of the nice features of this climb were my first glacier crossing (just below the summit) and some nice camaraderie with other climbers. I met some Bavarians on the way up who encouraged me to cross the slushy glacier without crampons, and I’m very grateful to them for their companionship. I probably didn’t have any business going out on the glacier without more equipment, but whatever. When my iPhone died on the summit, I asked one of the Bavarians on the way down if I could quickly text my wife to tell her how long it would take before I got down (to avoid last summer’s iPhone battery bullshit). She said (in dialect, of course): “Of course, we’re Bergfreunde (mountain friends)!” That’s the spirit.
