Thanks Matthew! This is super helpful. I will take your advice. I’m leaning towards the first option you suggested towards Molde after riding Aursjøvegen. (I’ve got a gravel bike so adding some more gravel sounds great). Better yet, I would ideally like to connect:

1) Nasjonal Sykkelrute 4: Hallingdal
2) Nasjonal Sykkelrute 4: Skarveheimen Rundt (only the western half ending Flam) to ride the Rallarvegen
then somehow connect between Flåm and Nasjonal Sykkelrute 3: Fjord og fjell or Nasjonal Sykkelrute 6: Sognefjellsveien
3) and then ride Nasjonal Sykkelrute 3: Fjord og fjell to Alesund and continue on the Eurovelo 1: Atlantic Coast Route all the way North

Any advice on this would be super helpful. Or if you recommend something more similar to my original suggestion in the prior post I will just stick to that.
Thanks!
