This section is marked on the map as a main road but it isn't. It starts as a lovely gravel road but gradually losses it's width and quality to become single track and goat passage. Don't take me wrong, I enjoyed every minute of it but I love hills and I had enough time. There are some steep sections that you will have to push your loaded bike.
Plan you time accordingly so you can enjoy scenery and nature along the way. There are no stores or houses along the way so get your supplies beforehand.
Enjoy and respect.
