Jornet Summits Everest Again Sans O2

Kilian Jornet has reached the summit of Everest for his second time on May 27 after reaching it on May 22. He did not use supplementary oxygen on either ascent.
On his first climb, he set out from base camp and reached the summit 26 hours later. On his second, he reached it after 17 hours from advanced base camp.
Conditions were sub-optimal for his second ascent and the 29-year-old returned to advanced base camp after 28 hours.
“I’m so happy to have made the summit again,” said Jornet. “Today I felt good although it was really windy so it was hard to move fast. I think summiting Everest twice in one week without oxygen opens up a new realm of possibilities in alpinism and I’m really happy to have done it.”
In 1996, Hans Kammerlander from South Tyrol reached the summit in 16 hours and 45 minutes from advanced base camp. Kammerlander made the first ski descent of the mountain on the same climb.
In 2007, Pemba Dorje Sherpa reached the summit twice in a week up the north face without bottled oxygen.
Reinhold Messner and Peter Habler were the first climbers to reach the summit of Everest in 1978 without bottled O2. By 2016, there were over 160 ascents without supplemental oxygen. In 2017, there will be at least a dozen climbers to do it.
Cory Richards reached the summit this past weekend with Adrian Ballinger, Ballinger without bottled oxygen. This is Richards’s second time on the summit in as many years. In 2016 he reached the top, but Ballinger had to turn around.
Ralf Dujmovits was also attempting from the north, solo without bottled oxygen but had to turn around due to conditions. He first reached the summit in 1992 with bottled oxygen.
There have been a number of deaths around the world’s highest mountain this spring, including that of the great alpinist Ueli Steck who fell from Nuptse over a month ago.
There have also been a number of reports of climbers dying, only to arrive to base camp hours later. One of the few cons of having high-speed internet in the death zone will be rushed reports, but there are far more pros.
