Surprise K2 Summit: Serge Hardy Tops Out Solo

On August 12, 2025, French climber Serge Hardy achieved a remarkable solo summit of K2, one day after the commercial teams had already reached the top. Contrary to earlier reports suggesting he had called off his attempt, Hardy pressed forward, turning to supplementary oxygen from the Bottleneck onward, ensuring his historic ascent.

A Season of Silence and Secrecy

This season on K2 was marked by limited information. Hardy confirmed with Explorersweb facts about the various teams were difficult to verify, and he described the leaders in Base Camp as “James Bonds in down jackets.” The competitive and secretive atmosphere created a tense “spy game,” where climbers wondered aloud: Will they go? Will they not? Hardy detailed the strained dynamics between big commercial teams and self-supported climbers, who were outfitted only as far as Base Camp by small Pakistani outfitters. As rumors of a weather window emerged, no one openly shared plans. Hardy needed both favorable weather and access to ropes, which only the large Nepalese expeditions could provide. Hardy expressed gratitude to the Madison Mountaineering staff, who lent him a spare sleeping bag when his own tent at Camp 2 had been destroyed by crows, and his sleeping bag had blown away.

Waiting for the Right Moment

By August 10 at Camp 3, Hardy observed that no climber would disclose summit plans. That night, all commercial teams departed, but Hardy stayed an extra day, encouraged by forecasts predicting a three-day window of suitable weather. The next morning, under clear skies and calm winds, Hardy recounted:

“The next day, under a blue sky and no wind, only the click-clack of my crampons pierced the silence.”

At Camp 4, he took a brief break before deploying his “secret weapon” – a single oxygen bottle purchased in Base Camp. Hardy described the effect as transformative:

“Even at the lowest flow, I suddenly transformed into Superman, trotting through the Bottleneck,” he admitted, though he acknowledged exaggerating slightly.

Summit and Conditions

Hardy reached the summit of K2 on August 12, completely alone. He described the contrast in conditions:

“On the Chinese side, a strong wind is blowing. On the Pakistani side, it’s like St. Tropez; we could put on a T-shirt, take a little nap, read a book…”

Challenges for Other Climbers

Except for Gulnur Tumbat from Turkey, climbers who summited on August 11 have yet to report details on the perilous descent. Rockfall turned lower sections of K2 into a literal shooting gallery. Climber Lenka Polackova, who summited without oxygen, commented on the challenge:

“While everyone is celebrating the summit, we are celebrating the return…I have never been more grateful for it. The mountain did not make it easy for us until the last moment.”

Most other clients and guides posted only summit pictures or celebratory messages.

Tragically, Jing Guan, a Chinese climber, died below Camp 1 after being struck by falling rocks on her descent. One rescuer assigned to retrieve her body was also hit by a rock but was later assisted down safely. Karrar Haidri of Pakistan’s Alpine Club confirmed that Base Camp is now empty.

This season’s K2 ascent highlights the perils, unpredictability, and extreme isolation faced by elite mountaineers. Hardy’s solo summit stands as a testament to courage, perseverance, and strategic use of oxygen, even amid the tense and competitive dynamics of modern Himalayan expeditions.
