The 32-year-old specialist in high-speed ascents – made without the aid of oxygen – left K2 base camp just after midnight on Saturday and reached the summit 10 hours, 59 minutes and 59 seconds later.

Vedrines attempted the summit in 2022 but was forced to turn back after suffering from hypoxia, a lack of oxygen in the blood caused by thin air at high altitudes.

“I took my revenge on this mountain,” Vedrines said in a voice message shared with AFP. “But above all I wanted to reconcile with it by doing things with maturity.”

“It was very symbolic for me because I was returning in my footsteps to where I experienced those very unique moments,” he said. “I really enjoyed seeing the same sections again, but with lucidity this time.”

Standing at 8,611 metres (28,251 feet) on the Pakistan-China border, K2 is 238 metres shorter than Everest but is considered more technically challenging – earning it the nickname “Savage Mountain”.

Vedrines is considered one of France’s pre-eminent climbers and set a speed record climbing Pakistan’s Broad Peak in 2022 before descending by paraglider.

He reached the top of the 8,051-metre mountain – a short distance from K2 – in seven hours and 28 minutes.
