I too, really, really like the Wise Guides. The problem I have is that they exist for so many routes, but not the Camino from Madrid. I do realize that this route is not as ancient as the others, but still, is is a viable route, is recognized as a formal Camino and an increasing number of people do walk it.
My situation is that I am leaving next Monday (only 6 days!) to fly into Madrid, and to walk to Santiago de Compostela from there. I do have the very good CSJ Guide to the Camino de Madrid, authored by our own Johnnie Walker. It does need some refreshing and I agreed to provide input to the next edition of this popular guide where possible from my direct, current observations.
But, I would have liked something better and usable on my iPhone. I follow the arrows each day, all day. But, I do like to know as much about where I am and where I am about to be, as possible.
I do wish the Wise Guide folks would undertake this as a new version.
I hope this helps.
