The doors have closed behind Ralf Dujmovits and Nancy Hansen. The so far only German climber who has scaled all 14 eight-thousanders and his Canadian partner moved in a 110-square-meter hypoxia chamber of the German Aerospace Center (DLR) in Cologne on Tuesday. As reported, the two mountaineers are participating in a study conducted by DLR in cooperation with the University of Texas to investigate whether extreme hypoxia can also have a positive side effect for human beings. US researchers from Texas found in two experiments with mice that heart muscle cells devided when the animals were exposed for two weeks to oxygen deficiency corresponding to conditions at 7,000 m. In mice which had previously been triggered myocardial infarctions, cardiac function improved after two weeks of hypoxia.
Medical control around the clock
Ralf and Nancy, both healthy, are the subjects of the pilot study. They are to stay in the hypoxia chamber for about a month. In the first few weeks, acclimatization as on a Himalayan expedition is simulated. The oxygen percentage in the air will be gradually lowered and temporarily increased only twice in between – as if the two climbers would descend again to breathe thicker air. The last two weeks, the 56-year-old German and the 49-year-old Canadian are to spend in a simulated height of 7,000 meters. The experiment can be stopped at any time in case serious problems arise. A DLR research team monitors Dujmovits’ and Hansen’s state of health around the clock. The daily schedule includes heart and lung function checks, blood and urine tests, fitness checks and so-called “cognition tests”, which check the reaction and perception of the subjects.
Yesterday, I visited the two climbers in their new “home”. That was possible on Wednesday for the last time without breathing mask. After more than half hour in a simulated altitude of about 3,700 meters, I felt a little bit dizzy. I preferred to do the interview with Ralf subsequently in thick air, by phone.
Ralf, you can not get out, there is no daylight, and the oxygen is lowered. That does not sound like a holiday apartment.

This seven-thousander has neither a summit, nor does it offer impressive views. It covers an area of only around 110 square meters – and is located on the grounds of the German Aerospace Center (DLR) in Cologne. A hypoxia chamber within DLR’s medical research lab “:envihab” – the name stands for environment and habitat – will be comfortably furnished in the coming months.
Four weeks in the chamber
In mid-May, Ralf Dujmovits, the only German mountaineer who has climbed all 14 eight-thousanders, and his partner, the Canadian climber Nancy Hansen, will move in there for four weeks. They are taking part in a highly interesting hypoxia study conducted by DLR in cooperation with the University of Texas. The assumption: Although extreme oxygen deficiency threatens life, there could also be a positive effect on the body.

It was the day of encounters. At first I cycled – for a change, in sunshine – along with a Swiss from the town of Zug, in his mid-60s, tanned, on a mountain bike that had already seen better days. “I’ve stopped working after 45 years,” the cyclist told me. “And now I am fulfilling my life dream. I always wanted to make a long bike trip.” I asked him how much time he took for the ride along the Rhine. “I’ll see how far I get until winter,” he said, grinning. In the further conversation it turned out that he was also a passionate mountaineer. He had climbed all four-thousanders of his home country, said the Swiss: “Actually, I had always dreamed of climbing Mount Everest one day. But tourism on this mountain has nothing to do with the way of climbing that I like.”

“Everything has been going well so far.” Ralf Dujmovits is highly satisfied with his acclimatization tour in the Khumbu area. To prepare for Mount Everest, the 55-year-old, along with his partner Nancy Hansen from Canada, climbed the 6440-meter-high Cholatse. Last Thursday they reached the summit. The climb via the Southwest Ridge was anything but easy, Ralf writes to me: “A good part of the route above the col leads over steep to steepest penitents – very, very uncomfortable to climb.” Dujmovits believes that the climb to the highest point will soon change drastically. “The summit structure of Cholatse threatens to break apart in the next few years,” says Ralf. “There are many crevasses up to the summit. 30 meters below the highest point you have to cross a snow bridge which is still only two meters long and half a meter wide. If this also breaks, you need a ladder to get to the top.”

Never say Never Again! This is not only the title of an old James Bond film but could also stand for Ralf Dujmovits’ personal story on Mount Everest. The first and so far only German, who has scaled all 14 eight-thousanders, had climbed the highest mountain on earth on his very first attempt in fall 1992. Due to bad weather, however, he had used bottled oxygen above the South Col. “I was very young at the time. It was a mistake,” says Ralf today.
After all, he climbed the other 13 eight-thousanders without breathing mask. And so he later tried to wipe out this Everest mistake again and again. In vain. In 1996, 2005, 2010, 2012, 2014 and 2015 he returned without summit success, for various reasons. This spring, the 55-year-old wants to give it a try again. For the eighth time, he will travel to Mount Everest, the fifth time to the Tibetan north side of the mountain. He will acclimatize in Nepal with an ascent of the 6,501-meter-high Cholatse in the Khumbu area, along with his Canadian partner Nancy Hansen. Ralf has now arrived in Kathmandu. I spoke with him shortly before he left to Nepal.
Ralf, I think, it’s allowed to say, that you and Everest have a relationship.

It is raining – at 9 p.m. at 5,000 meters in the Karakoram. “It’s incredibly warm here,” Ralf Dujmovits, Germany’s most successful high altitude climber, tells me via satellite phone from the Base Camp at the foot of Praqpa Ri. “We sat together until late in the evening with an open tent.” The unusually warm weather has resulted in difficult conditions on the seven-thousander so that its summit remains virgin. Like before on the also unclimbed seven-thousander Gasherbrum VI the 54-year-old German and his 47-year-old Canadian partner Nancy Hansen had to abandon their summit attempt. “We fought for every meter on ascent,” says Ralf. In vain.
Ralf, how far up did you climb this time?

The seven-thousander Gasherbrum VI in the Karakoram in Pakistan remains unclimbed. 54-year-old Ralf Dujmovits, Germany’s most successful high-altitude climber, and 47-year-old Canadian Nancy Hansen abandoned their attempt to first climb the 6,973-meter-high mountain (other elevation: 7,004 meters) in the Karakoram. They turned around at an altitude of 6,400 meters. “We did our best,” Ralf tells me via satellite phone. “Nancy fought in the slabs like a bear. It just was not meant to be. Finally we don’t want to commit suicide.”

“Really annoying that this happened to me at the very beginning!” Ralf Dujmovits, Germany’s most successful high altitude climber, is upset that he has first suffered from diarrhea and then from a bad cold while trekking on the Baltoro Glacier. “Meanwhile I feel better, but I realize that I still lack power,” Ralf tells me, when I reach him on satellite phone during an exploration trip. The 54-year-old and his girlfriend, the 47-year-old Canadian climber Nancy Hansen, traveled to the Karakoram in order to try first ascents of two still unclimbed mountains: first Gasherbrum VI (the reported altitude varies between 6,973 and 7,004 meters), then, not far away, Praqpa Ri (different elevation data too: 7,134 or 7,152 meters). The two climbers have pitched up their Base Camp at the foot of Gasherbrum VI.
Ralf, how have you experienced Pakistan so far? The country is still said to be a risk area.

Ralf Dujmovits is one of the many climbers who have already failed in winter on Nanga Parbat. The first and so far only German who climbed all 14 eight-thousanders tried to scale the 8,125-meter-high mountain in Pakistan at the turn of 2013/2014 after having acclimatized previously on the 6,962-meter-high Aconcagua, the highest mountain in South America. At that time Ralf abandoned his expedition relatively quickly because he thought the danger of ice avalanches on the Messner route was by far too high. I met the 54-year-old this week at the trade fair ISPO in Munich.
Ralf, at the moment much is happening on Nanga Parbat. Are you not itching to go there again?

Ralf Dujmovits is shocked. “I have rarely seen something so depressing and sad”, says Germany’s most successful high altitude mountaineer when he calls me from Kathmandu. He has just returned from an all-day trip to Sindhupalchowk District, about 80 kilometers northeast of the capital. There was no other district in Nepal where the devastating earthquake two weeks ago killed more people than in Sindhupalchowk. So far, the government has registered there more than 3,000 dead – at a total of more than 7,900 fatalities throughout Nepal.

China shows its friendly face. For 10 May, the Chinese government is planning “to provide a charter flight free of charge form Lhasa to Kathmandu for all Sherpas – not just for Climbing Sherpas, but also for cooks and kitchen helpers”, Ralf Dujmovits wrote to me calling it “a generous gesture” – despite the expected propaganda of the Chinese. The most successful German mountaineer arrived in Lhasa, like many other western climbers who were on expedition in Tibet. “The China Tibet Mountaineering Association (CTMA) generously bears the costs of transport to Lhasa, accommodation and meals. And they take care of the visa formalities for the stranded climbers coming from all Tibetan peaks”, the 53-year-old said.

His bookmark is still in the book of Everest. Ralf Dujmovits scaled all 14 eight-thousanders, as the only German so far. Only on Mount Everest in 1992, Ralf used bottled oxygen – something that the 53-year-old sees as a blemish by today. This spring, Ralf wants to travel to the highest mountain in the world for the already seventh time, for the fourth time to the Tibetan north side. Last year Dujmovits reached there an altitude of 8,300 meters on the northeast ridge. At that time he got angry about his own mistakes. And so Ralf’s repeatedly announced “definitely last” attempt on Everest became once again just his most recent try. This year, he wants to climb in a team with the Canadian Nancy Hansen. I met Ralf at the trade fair ISPO in Munich and asked him about his Everest plans:
Ralf and Mount Everest, a never ending story?
