I live between E and F on your planned route, contact me if you need any help -advice?- around there. By the way, a nice place very near your waypoint E: http://www.hotelsemaforodebares.com/en/
, the gardens around the hotel have free access, with an amazing view of the Ria do Barqueiro and the point where the Cantabric sea meets the Atlantic ocean. The hotel has a wonderful terrace but not sure it will be open in October.
Thumbs up for your ride!
