Could you ski mountaineer 23,000' in under 20 hours?

A unique quest was recently accomplished and it involved two french ski mountaineers, seven 14,000' peaks, 20 hours, 65 km and 23,000' of climbing.

Here's the details:

Mammut Pro Team athlete Beni Hug and French ski mountaineer climbed all seven four-thousander peaks of the Aletsch area on touring skis in only 20 hours. With a total of 7000 altitude meters and a distance of approx. 65 km, Beni and Tony completed their personal records.

On midnight of May 10th, the endurance specialists set out for their speed ascent at the Jungfrau Saddle. The route took them first across the Mönch (4108m) and Jungfrau (4156m) via the Jungfrau Firn and on to Greater Grünhorn (4051m) as well as the Fiescherhorn peaks (4032m/4051m). Finally, they had to climb the highest peak of the Bernese Alps, the Finsteraarhorn (4270m), to eventually end their route via the Grünhorn gap with the region’s second-highest peak, the Aletschhorn (4210m). For «normal» ski mountaineers, every single one of these mountains constitutes a good day’s tour. Tony and Beni conquered a total of 7000 altitude meters in only 20 hours on their touring skis, while crossing a distance of approx. 65 km.”
