A team of young French alpinists has climbed a major new mixed line in alpine style on the 2,100m south-west face of Latok II in Pakistan's Karakoram range.

Due to unsettled weather Antoine Bletton, Pierre Labbre, Mathieu Maynadier and Sébastien Ratel were only able to acclimatize with one night at 5,800m, before receiving a text message that there would be a three-day weather window followed by 10 days of snow.

Despite feeling three days was not enough, the four moved up to the base of the wall and bivouacked....

...The route has been named Théorème de la Peine (ca 2,000m, ED1, M5).
