All good things come in threes, people say. On his third attempt, Andrzej Bargiel succeeded in scaling Mount Everest without bottled oxygen and skiing from the summit back down to base camp. “It’s one of the most important milestones in my sports career. Skiing down Everest without oxygen was a dream that had been growing inside me for years,” said the Pole.

He had abandoned his first attempt in fall 2019 because a monster serac around 50 meters high and 30 meters wide was hanging over the Khumbu Icefall and threatening to break off. His second attempt ended in fall 2 0 22 at the South Col at almost 8,000 meters, where the wind was so strong that it was impossible to pitch a tent.

Tyler Andrews abandons Everest speed attempt

The final stop was at around 7,400 meters. After almost ten hours of climbing, Tyler Andrews decided to abandon his speed attempt on Mount Everest and descend again. “Slower pace than planned, snow has gotten worse and harder to break through solo,” it said on his website.

The 35-year-old long-distance runner from the USA wants to climb Everest without bottled oxygen – and faster than anyone has ever done before. The current record for reaching the summit without a breathing mask from the Nepalese south side is 20 hours and 24 minutes, claimed in 1998 by Nepalese mountaineer Kaji Sherpa.

45 years ago: Reinhold Messner’s solo ascent of Mount Everest

“In 1980 on Everest, I was more wiped out than ever before and not even after that,” Reinhold Messner told me five years ago when we talked about 20 August 1980—the day he stood alone on the summit of the highest mountain on earth.

“I had fantastic weather, was very well acclimatized and made very good progress in the lower part of the mountain. That made me feel cheerful and confident. A few hundred meters below the summit, however, the weather closed up. Fog crawled up from the south side, spilling down over the ridges and the summit to the north. I was suddenly afraid that I would lose orientation. Tiny snowflakes were drizzling.”

Denis Urubko and Maria Cardell report: New route on Nanga Parbat

“On 10 July at 11:30 a.m. local time, we stood on the summit of Nanga Parbat after climbing it via a new route in alpine style,” Denis Urubko wrote yesterday to the Russian mountaineering portal mountain.ru. “Maria and I are happy.”

Urubko and his Spanish wife Maria “Pipi” Cardell had already travelled to Pakistan at the beginning of June to acclimatize for their project on the 8,125-meter-high Nanga Parbat. Their goal: a new route through the Diamir Face, the western flank of the ninth highest mountain on earth. In alpine style, i.e. without bottled oxygen, without fixed ropes, without fixed high camps and without high altitude porters.

Klara Kolouchova dies on Nanga Parbat – Horia Colibasanu reaches the summit without breathing mask

Mourning for Klara Kolouchova. The 46-year-old Czech woman fell to her death on Nanga Parbat on Thursday. “An experienced mountaineer, she fell while descending above Camp 2. She was accompanied by her Sherpa, Taraman Tamang, when she slipped on a rocky section of the mountain,” the Nepalese expedition operator Seven Summit Treks (SST) announced on Instagram.

Kolouchova was the first Czech woman to scale the three highest mountains in the world, Mount Everest (in 2007), K2 (2019) and Kangchenjunga (2019) – in commercial teams, with bottled oxygen. She has also stood on the summits of the eight-thousanders Cho Oyu (2006) and Annapurna I (2024).

Last summer, she failed on Nanga Parbat. Due to the difficult conditions, the end of the line was reached in Camp 2 at around 6,200 meters. “Last year, the ‘Naked Mountain’ (translation of Nanga Parbat) stripped me to the bone,” she wrote in her last Facebook post on June 16. “This year, we want to climb to the summit.” Her husband was also part of the team.

David Göttler after success on Nanga Parbat: “Highlight of my mountaineering career”

Even after returning to his home in Spain, David Göttler still seems to be floating on cloud nine. “It will probably take a month before the euphoria subsides and I can realize it all,” the 46-year-old German climber tells me.

On Tuesday last week, Göttler – together with French female climber Tiphaine Duperier and her compatriot Boris Langenstein – scaled the 8,125-meter-high Nanga Parbat in Pakistan.

It was only the eighth ascent of the mountain via the challenging Schell route. An Austrian expedition led by Hanns Schell first climbed this route to the summit of Nanga Parbat in 1976. It leads via a pillar on the left side of the Rupal flank to the almost 7,000-meter-high col between the Mazeno Ridge and the Southwest Ridge. At 7,400 meters, the route changes to the Diamir side.

Anja Blacha after her success on Mount Everest: “The summit seemed even more littered to me”

A week ago today, German mountaineer Anja Blacha experienced something on Mount Everest that is now a rarity: she had the summit all to herself – because she was the last summit contender of the spring season to reach the highest point on earth at 8,849 meters and was on her way without a Sherpa companion. One day later, the Icefall Doctors declared the season over and began dismantling the ropes and ladders through the dangerous Khumbu Icefall above Everest Base Camp. This deprived Anja of the chance to attempt the neighboring 8,516-meter-high Lhotse without bottled oxygen.

So be it, Blacha can be pleased to be the first German mountaineer and only the eleventh woman in the world to have stood on Mount Everest without a breathing mask. A remarkable achievement that stands out from the almost 800 Everest ascents this spring.

This means that she has climbed twelve of the 14 eight-thousanders – in commercial teams, on the normal routes – without supplemental oxygen. Only Lhotse and Shishapangma in Tibet are still missing from her collection of eight-thousanders. After her safe return from the mountain, Anja Blacha answered my questions.

Anja, first of all, congratulations on your ascent of Everest without bottled oxygen. It was your third summit success on Mount Everest, and you used a breathing mask on the first two. How did you experience the difference – with/without additional oxygen?

Breaking news: Anja Blacha is the first German woman to scale Mount Everest without bottled oxygen

“At the moment, I see it above all as an unbalanced combination of numbers.” That was Anja Blacha’s answer a week and a half ago when I asked her what it meant to her that she had climbed eleven of her twelve eight-thousanders without bottled oxygen. Now she has provided a balanced combination of numbers.

The 34-year-old German adventurer also scaled Mount Everest today without a breathing mask. “She was all alone on the summit,” Mingma Gyalje Sherpa, head of the expedition operator Imagine Nepal, informed me at around 8.30 a.m. Central European Summer Time. According to Mingma, Blacha had climbed to the highest point on earth without bottled oxygen and without a Sherpa companion.

Sirbaz Khan – the first Pakistani to climb all eight-thousanders without bottled oxygen

“I am delighted for Sirbaz that he has now also completed the 14 eight-thousanders ‘topless’,” writes Ralf Dujmovits, Germany’s most successful high-altitude mountaineer. “My heartfelt congratulations to him.”

Sirbaz Khan has fulfilled his self-proclaimed “Mission 14”: On Sunday at 11.50 a.m. Nepalese time, the 37-year-old reached the summit of Kangchenjunga at 8,586 meters with the team from expedition operator Imagine Nepal. Sirbaz also scaled the third highest mountain on earth without a breathing mask. This makes him the first Pakistani to climb all 14 eight-thousanders without bottled oxygen.

Anja Blacha after her Dhaulagiri summit success: “Not in competition with other German female high-altitude mountaineers”

“So, what’s next? Another record-setting expedition? Maybe. As a by-product,” writes Anja Blacha on her website. “Rather than defining my goals based on records, I like to let curiosity guide my way. Following my interests, and living up to my values, virtues, capabilities. The art of striving well. Eudaimonia.” This term from Greek philosophy is made up of “Eu” (good) and “daimon” (demon, spirit). In other words, Anja is trying to live out her own good spirit.

And the 34-year-old German adventurer does this very persistently. This is how Blacha reached the South Pole on skis in the winter of 2019/2020, after pulling her sledge almost 1,400 kilometers from the coast of Antarctica, alone and without outside support.

She has scaled Mount Everest twice – in 2017 via the Tibetan north side and in 2021 via the Nepalese south side. And with her successes on Annapurna I and Dhaulagiri this spring, she has summited twelve of the 14 eight-thousanders in commercial teams via the normal routes – with the exception of Everest, all without bottled oxygen. After her second eight-thousander summit success this season, Anja Blacha answered my questions.

Anja, first of all, congratulations on your 12th eight-thousander. The weather conditions were difficult at first. Then a weather window opened up. How did you experience the ascent and descent on Dhaulagiri?

Jost Kobusch after Everest attempt: “It would have been too dangerous to climb any higher”

Jost Kobusch on the West Shoulder of Mount Everest

Jost Kobusch kept a cool head on Mount Everest. On his first push this winter, the 32-year-old German climber reached an altitude of 7,537 meters on the West Ridge. The altimeter on his watch showed this value on 27 December. His GPS tracker measured the highest altitude at 7,488 meters. On another model, the figure was 7,553 meters. Such differences are not unusual for altimeters.

In any case, Jost climbed around 200 meters higher than during his most successful attempt to date in the winter of 2019/2020, when he turned back on the West Shoulder. This time, he sniffed into the upper part of the West Ridge. I asked Jost via WhatsApp if he hadn’t been tempted to pitch his tent there and climb further up.

Summit success on Cho Oyu – the tenth eight-thousander for Anja Blacha

Now she’s in double figures. Last Saturday (5 October), Anja Blacha and Ngima Dorchi Sherpa scaled the 8,188-meter-high Cho Oyu via the Tibetan north side, her fourth eight-thousander this year – “Ngima with, me without a breathing mask,” as Anja writes to me. “It was a bit windy, but otherwise the conditions were great.”

For the 34-year-old German, it was the tenth of the 14 eight-thousanders, the ninth without bottled oxygen. “I know my body well enough by now to know how it reacts to altitude and that it can usually cope with it. So why not do without this aid if I can?,” Blacha wrote to me at the end of September after her summit success on Manaslu.

Summit successes reported on Shishapangma and Cho Oyu

The first summit successes of the fall season on the eight-thousanders in Tibet are now perfect. The expedition operator Imagine Nepal announced that an eleven-member team led by Mingma Gyalje Sherpa reached the summit of Shishapangma at 8,027 meters today. Five team members had completed their eight-thousand-meter collection, it said: the Nepalese Mingma Gyalje Sherpa and Dawa Gyalje Sherpa, the US-American Tracee Lee Metcalfe, the Japanese Naoki Ishikawa and the Pakistani Sirbaz Khan.

Anja Blacha after her Manaslu success: “I had the summit to myself”

After the eight-thousander is before the eight-thousander. This year, this also applies to Anja Blacha, who has now climbed nine of the 14 highest mountains in the world. This makes the 34-year-old the German woman with the most eight-thousander summit successes.

Last spring, she first scaled Makalu (8,485 meters) and then Kangchenjunga (8,586 meters), both without bottled oxygen. She also climbed without a breathing mask during her successful ascent on Manaslu (8,163 meters) on Monday. Now Blacha wants to try her hand at Cho Oyu (8,188 meters). She answered my questions in Tibet.

Anja, Manaslu was your third eight-thousander summit this year. How did you fare on your ascent?

Anja Blacha after Kangchenjunga success: “Never had such heavy legs on the descent”

Now no other woman from Germany has stood on eight-thousanders more often than Anja Blacha. The mountaineer, who celebrates her 34th birthday on 18 June, achieved a last-minute summit success on the 8,586-meter-high Kangchenjunga, the third highest mountain in the world, at the end of the spring season on the eight-thousanders in Nepal. She had already scaled the 8,485-meter-high Makalu, the fifth-highest of all mountains, on 12 May. On both mountains, Anja climbed on the normal routes, with teams from the commercial expedition operator Seven Summit Treks (SST) and did without bottled oxygen herself.

These were her seventh and eighth eight-thousanders after Mount Everest (in 2017 and 2021), Broad Peak, K2 (both in 2019), Nanga Parbat, Gasherbrum I and II (these three in 2023). Only on Everest did she use a breathing mask on her ascents. This means that the German mountaineer now has one more eight-thousander summit success to her name than Alix von Melle, who has summited seven eight-thousanders to date. Anja Blacha answered my questions after her return from Kangchenjunga.

Congratulations, Anja. You scaled Makalu and now Kangchenjunga at the end of the spring season without bottled oxygen. With eight eight-thousanders to your name, you can now call yourself the most successful German female high-altitude mountaineer. How does that feel?
