Standing on top of the world at 4:00 AM in freezing, thin air isn't a casual walk in the park. For Kenton Cool, it just looks like one. On Friday, May 22, 2026, the 52-year-old British mountain guide stepped onto the highest point of Mount Everest for the 20th time. He already held the record for the most successful summits by any non-Nepali climber, and this latest achievement simply cements his place in mountaineering history.
People who look at the headlines might assume he is bored of the routine. They want to know when he will finally pack up his ropes and retire to his quiet village in Gloucestershire. But when Cool flew back into Kathmandu on Sunday, he shattered those expectations. He bluntly told reporters he wants to go back up maybe another two or three times. He changed his mind after claiming last year that his 19th or 20th climb would be his final bow on the big hill.
There is a massive problem with how we view Everest today, though. We see records breaking every single week, and we treat the mountain like a high-altitude playground. It's easy to look at a veteran like Cool and think the peak has been tamed. It hasn't. The real story behind his 20th summit reveals why the mountain is becoming more dangerous, how it's physically changing, and what it actually takes to survive it.

The Broken Feet and the Myth of Routine
People often think top-tier mountaineers are genetically superior beings who effortlessly glide up vertical walls of ice. The reality is far grittier. In 1996, Cool suffered an incredibly brutal accident. He fell from a rock face near Llanberis Pass in North Wales, completely shattering both of his heel bones. A specialist looked at the damage and told him he would likely walk with a stick for the rest of his life.
It took a year of intense surgeries, agonizing physical therapy, and sheer stubbornness to prove that doctor wrong. He didn't just learn to walk again; he joined the British Association of Mountain Guides. He spent months working high above the ground on industrial rope access projects, including the Millennium Dome, just to build back his comfort with extreme heights. When he first stood on top of Everest in 2004, it was a triumph over a body that was supposed to be broken.
Fast forward over two decades, and he has guided high-profile figures like Sir Ranulph Fiennes and Ben Fogle to the top. Yet, despite his unparalleled track record among Western climbers, Cool refuses to call the climb routine.
"It never gets any easier or any less frightening," Cool shared shortly after his descent. "It’s the tallest mountain in the world and with it comes an incredible sense of majesty. I rely on every bit of experience I have to move safely in this environment."
This is the mindset that separates survivors from statistics. While Nepal's legendary Kami Rita Sherpa pushes the absolute human limit with his mind-boggling 32 summits, Cool’s 20 ascents show what disciplined longevity looks like for an outsider.
The Climate Reality Shock at Base Camp
If you want to understand why Cool’s perspective matters, look at what he sees happening to the physical environment. He isn't just counting numbers; he’s watching an ecosystem collapse.
Because he has returned to the Khumbu region almost every year since 2004, he acts as an eyewitness to rapid environmental decay. He points out that the Khumbu Glacier is suffering from disturbing amounts of glacial loss. Back during his early expeditions, a river of meltwater would only appear at Base Camp at the very end of the climbing season. Today, that river flows constantly throughout the entire spring.
The data back up his observations. Glaciologists at the University of Leeds, where Cool originally earned his degree in Earth Sciences, have been tracking this through research projects. Satellite data shows that the area around Everest Base Camp has lowered by more than 50 meters since the 1960s. The glaciers are warming and melting at rates that defy historic precedent. The route Cool climbed in 2004 simply does not exist anymore; it is shifting, melting, and becoming far more unpredictable.
To combat this, Cool tries to practice what he preaches. His guiding company belongs to 1% for the Planet, meaning a portion of revenues goes directly to environmental charities. He offsets his expedition travel emissions and maintains a plant-based diet whenever possible. He knows his livelihood depends on the mountain, but he isn't blind to the footprint left behind by modern commercial guiding.
Overcrowding and the Race for Permits
Cool’s historic 20th climb happened during a week of absolute chaos on the mountain. On the Wednesday before his summit, more than 270 climbers rushed the peak from the southern side in a single day, taking advantage of a brief weather window. Photos from the high-altitude zones showed terrifying lines of people waiting on fixed ropes in the Death Zone, where the human body literally consumes itself due to the lack of oxygen.
Sadly, the exact same week Cool celebrated his feat, two Indian climbers died during their descent. The season’s death toll quickly climbed to five. Even Kami Rita Sherpa publicly voiced concerns, urging the Nepali government to regulate the crowds, vet the quality of the climbers, and enforce strict limits.
The surge in traffic over the last quarter-century is staggering. Nearly 16,000 people have gone above Base Camp in the past 25 years, which is nearly triple the amount from the preceding eight decades combined.
Cool isn't pulling up the ladder behind him, but he recognizes the current system is unsustainable. He actively champions a proposal that would radically change Himalayan guiding. The rule would force anyone applying for an Everest permit to first successfully summit a 7,000-meter peak elsewhere. This simple change would weed out wealthy tourists who lack basic crampon and rope skills, ensuring everyone on the fixed lines has earned their right to be there.
What You Should Take Away from the 20th Climb
If you love the outdoors or dream of high-altitude trekking, don't view Cool’s 20th summit as proof that Everest has become an easy, commercialized tourist trap. Treat it as a masterclass in risk management, physical resilience, and deep respect for nature.
If you want to apply this level of preparation to your own adventures, you need to shift your approach to training and planning.
Stop focusing entirely on physical endurance and start building technical competency. If you plan to tackle big peaks, don't just log hours on a treadmill with a heavy pack. Spend dedicated time practicing self-arrest techniques, cold-weather knot tying, and crevasse rescue until they become pure muscle memory.
You should also look closely at the ethics of the guiding companies you hire. Before booking any high-altitude trek or mountaineering expedition, ask tough questions about their waste management policies, how they treat their local porters and Sherpas, and what steps they take to minimize their environmental impact. Choose operators that value sustainability over a 100% summit guarantee.
Finally, build a progression plan into your climbing goals. Avoid the temptation to jump straight to iconic, massive peaks just for the social media bragging rights. Spend seasons cut-testing your gear and your mental stamina on smaller, highly technical peaks first. True expertise isn't about reaching the top once by luck; it's about having the skills to get back down safely every single time, just like Kenton Cool has done for over two decades.
