Marek Holeček finished his many years long project, it was his 5th attempt.

Last year he was there with  Czech climber Ondra Mandula.  After bivouac in 7700 m they had to escape because of bad weather then.

In 2015 tried the ascent with Tomáš Petreček and they had returned in 7000 m because of weather.

And before he was there 2x with Czech Mountaineering Union chairman Zdeněk Hrubý, who had died there during the 2nd attempt.
