Recently a new Facebook group called "In het spoor van Olav de Heilige" and is meant to exchange information and experiences on cycling over the Olav's way. The group is still public (unless to much 'unwelcome guests' start riding in)
Hopefully we can go to Norway this summer so people can exchange a lot of information after that!
For now you'll have to make do with the information on the website Via Gaia. Or you buy the guide... 😉
On the website of Norwegian Institue of Public Health you can monitor the situation to see if you're welcome again in Norway.
