Mountaineering icon Nirmal “Nims” Purja has redefined the limits of human endurance once again, setting a blistering new world record for the back-to-back ascent of Mount Everest and Lhotse without supplemental oxygen. Completing the high-altitude traverse in just 13 hours and 42 minutes, Purja dismantled his own previous record of approximately 25 hours.
The feat was far from a solitary sprint. Purja was actively managing a team of exclusive VIP clients during the most volatile phase of the season. Following a two-day stint in the “Death Zone” at Camp 4, where he balanced the safety and nutritional needs of his clients against the brutal conditions, Purja launched his summit push. After guiding his team to the top of Everest, he bypassed the typical recovery period to immediately tackle the 8,516-meter peak of Lhotse.
“No oxygen. No sleep. No limits,” Purja wrote on social media following the expedition. “The pain was the prize.”
The route between the two summits presented significant obstacles, including deep, fresh powder that required the climber to blaze his own trail while “fighting gravity itself.” Despite the exhaustion of leading an expedition, Purja described the internal drive that propelled him through the traverse: “I needed to push past the pain barrier…To understand and to remind myself again what happens when your body is screaming and your mind takes the wheel.”
Purja is currently the only person in the world to have successfully completed the Everest-Lhotse traverse back-to-back without supplemental oxygen. While his name is synonymous with high-speed mountaineering records, he maintains that these achievements are secondary to his broader commitment to professional guiding. “This isn’t ego,” Purja noted. “This is purpose!”
Purja, who famously completed all 14 of the world’s 8,000-meter peaks in record time and led the first winter ascent of K2, continues to operate his expedition company, Elite Exped, while simultaneously chasing these elite athletic milestones.
