For cyclists, there is the Facebook group In het spoor van Olav de Heilige(In the footsteps of the Holy Olav) Here you can exchange experiences or ask questions. It's in Dutch, but feel free to ask something in English. You can also find news and information on Via Gaia's Facebook page and Instagram page.
Agenda
To promote the guide, I started giving presentations and interviews. These are all in Dutch, but if you’re still interested, you can find links to them Dutch news page. What’s interesting, even if you don’t understand Dutch, is that I have an introduction clip for a presentation, on Youtube, which gives you an impression of the Gudbrandsdalsleden by bicycle. I narrated it myself, but you can enable subtitles which are automatically generated, on the bottom right of the video player.
