My second 4000m peak in the "going light and fast"- manner. With the trail-maniacs crew (Natalia, Christoph and Harald) we conquered together the broad summit of Alphubel in shorts in 4hours and 36min (incl. breaks), had a blast running down the steep snowfield and finally arrived tired and exhausted but satisfied after 8hours the church of Täsch in the centre.
The crux of the route, named Eisnase, a 40 degrees steep ice field, was still covered with snow at that time. Just 3 meters started to become icy. If you wanna run up Alphubel, try to find these passage in snow-covered conditions given the fact that Eisnase is very exposed and sketchy to climb up/down with snow chains under your feet. Alphubel glacier isn't a big risk for crevasse fall, we didn't use a rope or brought glacier equipment with us. Going light and fast on this route works very well...
