BRIEFING

Jett here, and what happened on Mount Everest a couple years back is either a glimpse of the future or the start of a really messy fight about shortcuts, safety, and who gets to rewrite the rules. It's a doozy and really interesting. Let’s get into it.

Back in May 2024, four former British special forces soldiers pulled off something that made the mountaineering world do a double take. They went from the U.K. to the summit of Mount Everest in just five days. Not five weeks. Not the usual two months. Five little short days.

CRAZY!

That’s a big deal, folks, because humans aren’t meant to hang out at the cruising altitude of a 747. And if they do try it, it usually takes about two months of hardcore, well-structured acclimatization.

To understand why this "5 days" matters, you have to understand how Everest usually works. Climbers spend weeks slowly and painstakingly acclimatizing to the altitude because the human body does not handle thin air well. Move too fast and you risk altitude sickness, fluid in the lungs, or worse... death. That slow grind up the mountain has always been part of the price of admission, which isn't cheap.

These guys thought two months was way too long. They decided to compress the timeline. They trained for months at home using hypoxic tents and restricted-oxygen workouts to simulate the high altitude of Everest. And then came the really controversial part. Shortly before the climb, they underwent a supervised xenon gas treatment in Germany, a move they hoped might give their bodies an extra edge in handling low-oxygen conditions.

Four British men have successfully completed a controversial high-speed expedition on Mount Everest, reaching the summit in just five days with help from xenon gas.

The climbers—who are all former special forces soldiers—left the United Kingdom on May 16. By 7:10 a.m. on May 21, they were standing on the top of the 29,032-foot-tall peak, according to Agence France-Presse.

Garth Miller, Alistair Carns, Anthony Stazicker and Kevin Godlington climbed the towering peak with help from the Austrian guiding company Furtenbach Adventures. The team also included five Sherpa guides and a cameraman.

Climbers who want to scale Everest typically must spend weeks or months acclimatizing to the altitude. But the team was able to complete the expedition, which doubled as a fundraiser for veterans, in a fraction of the normal time.

They pulled off the feat in part because they spent months preparing at home. They slept in hypoxic tents, or chambers with low oxygen levels meant to mimic the effects of high altitude, and exercised while wearing masks that restrict oxygen.

On May 5, they also inhaled xenon gas, reports the Washington Post’s Cindy Boren. After being lightly sedated at a clinic in Germany, the men breathed in a low dose of xenon gas mixed with oxygen for less than an hour.

It’s not clear what effect, if any, the xenon gas treatment had on the climbers. First discovered in the 1880s, the noble gas was long used as an anesthetic. Past research has found that it boosts the production of erythropoietin, a protein produced by the kidneys that helps increase the number of red blood cells in the body, typically in response to low oxygen levels. Erythropoietin also increases hemoglobin, which transports oxygen throughout the body.

Supporters say this is simply smart preparation evolving with the times. Critics say it smells like a shortcut that could undermine both safety and the spirit of high-altitude climbing. The science itself is still murky. Some research suggests xenon can stimulate the body’s production of red blood cells, which help carry oxygen. Other experts say the performance benefits in the mountains are unclear or possibly nonexistent, and misuse could even be dangerous.

But they successfully pulled it off and shook the climbing world to its core.

High-altitude mountaineering has no single global governing body, and while the World Anti-Doping Agency banned xenon in certain sports back in 2014, those rules don't apply on Everest. So now the sport is staring at this question: if the technology exists to make something faster or safer, who decides whether it crosses the line?

DEBRIEFING

There is also some other tension brewing underneath all of this. Some critics worry that faster expeditions could disrupt the traditional Everest economy, including the Sherpa-led guiding structure that's supported the climb for decades. Others argue that reducing the time climbers spend in the death zone could lower overall risk. Both arguments carry weight, which is why this story is not going away anytime soon.

For now, one thing is clear. The five-day Everest summit was not just some flashy, cool headline. It's now a test for the old rules of extreme performance.

NOW YOU KNOW

Whenever humans find a way to compress risk, time, and suffering all at once, the arguments always heat up.
