Offline, you’ll find me outdoors.
Father of three. Freerider, ski touring in the High Tatras the moment it snows. Enduro mountain biker, doing a Transalp expedition every year. Marathon runner, mostly training on trails in the forests around my hometown, with my White Swiss wolf. Often sleeping in an old Land Rover, somewhere in the woods.
