Hi, C clearly. I rarely have the quickest or easiest tech solution, but what I like to do is use wikiloc.com. I go stage by stage and can choose hiking/biking, etc. Then I tend to use the most recent one, but I do check it out to make sure it comports with my understanding. There are lots and lots of options, and once I find a user I like, I tend to stick with him/her for the rest of the route.
I am by no means an expert, but one of the problems you may have with downloading the entire Vdlp and Sanabres on your GPS is that there is a limited number of "points" that the device will take. When I download from wikiloc, even one short stage of 25 km or so has more points than the device will incorporate, so that means I check the box that tells wikiloc to transform the tracks into one with 500 points, which my device will incorporate. That is perfectly accurate enough for a 25-35 km stage, but would not likely be good for the entire route of the Vdlp or Sanabrea.
I once learned this the hard way. When Susanna and I were walking the Camino Olvidado from Bilbao, it turned out that the tracks that were loaded up had way more than the accepted 500 points -- which meant that we had tracks only for the first part of every stage. So it required re-loading with the "fewer points" version. Hope this makes sense. And I'm sure that the more savvy tech people on the forum can help.
(Maybe it is already somewhere obvious here, but I am new to downloading the tracks, so I'm not sure what I need to be aware of.)
