His interest for the outdoors origins from his childhood. The family summer residence was situated not far from the legendary polar explorer Knud Rasmussen's house and museum. There René enjoyed studying images and artefacts from the polar expeditions.

When René was around 20 years old, he went on his fisrt hike to Kebnekaise. In the following years it became an uncountable amount of treks and ski trips to the Kebnekaise mountains, Sarek, Padjelanta, Rondane, Jotunheimen, etc.

René founded “Vildmarksskolen” in 1992, which arranged courses in Mountain hikes, Mountain skiing and canoeing. Later he started “Vildmarksrejser”, which offered hiking and fishing trips to Greenland and the Nordic mountains, including ski trips in the North.

He has taught in outdoor living, mountian hiking and winter hiking and has conducted mountain trips for more than a decade.

He has for many years lived in Greenland and he knows how to build and sail a Greenlandic qaaq. Furthermore, he builds and drives Eastern Greenlandic dog sleds. He has also lived on the Faroe Islands for some years. These to stays have of course lead to even more hikes, skiing and dog sled trips. Rock and ice climbing as well as glacier hikes are more thing he has done.
