Sigurd has climbed on all seven continents and is one of the alpinists with the most impressive climbing resume in recent years. His achievements include several first ascents of big walls in Baffin, Canada, and the Karakoram, Pakistan, as well as numerous routes on big walls in Patagonia. Other notable peaks he has summited include Peak Lenin, Aconcagua, Alpamayo, and Mt. Kenya.

In 2005, Sigurd was part of the first Norwegian expedition to attempt K2, and in 2008, he was on the team that repeated the Norwegian Route on Great Trango Tower—an expedition considered a world-class climbing feat. Sigurd also has a passion for skiing, as demonstrated by his traverses of Svalbard, the Greenland ice sheet, and South Georgia on skis.

In Norway, Sigurd has led numerous guiding tours, including over 40 crossings of Jostedalsbreen Glacier, as well as other mountain and ski tours. Sigurd loves the tent life and enjoys every single day in the outdoors!
