Fastest ascent of all 14 eight-thousanders (with supplementary oxygen)

What to remember

Fourteen mountains rise above 8,000 metres (26,247 ft) and stand far enough from their neighbours to be recognised by the International Mountaineering and Climbing Federation (UIAA). All of them sit in the Himalaya and the Karakoram ranges of Asia.

Kristin Harila and Tenjen Lama Sherpa climbed every one of them together in 92 days, completing the run on 27 July 2023. Their record is for an ascent with supplementary oxygen, a separate category from climbs made without it: at those heights the oxygen pressure in the air is too low for people to stay long.

History gives the figure its scale. The first eight-thousander to be climbed was Annapurna I, reached on 3 June 1950 by the French climbers Maurice Herzog and Louis Lachenal; the others fell one by one through the 1950s and early 1960s.
