Hi
I rode this route in April via Ourense. I took a German guide book, but I do not speak German. I did this as it was the best one around. It did have maps and profiles, the profiles were more important to me. I also used mundicamino's website and used the profiles from there as well. As for the German book, at the start of each walking chapter, it does mention where the albergues, hotels etc are.
How far do you plan on riding each day? How many days are you looking at. I used godesalco website and planned my itinerary through this. It gave me another idea as to where I should ride to and then stay. I would then look at mundicamino and see if they had a place to lock up the bikes. To me, this is one of the most important aspects of the trip.
As an indication, I gave myself 12 days to do this trip, but I also planned a couple of extra days in case of problems, which we did have. My girlfriends rack broke a couple of times. Luckily there were 3 of us so we were always able to get to another village/town. Finding places to fix your bike is also a problem but there was always somebody who would help us or point us to a welder, mechanic, etc. For a country that has produced many world class cyclists, bike shops are few and far between. This is a secluded route so make sure you have your bike serviced before you go. I did this for mine and my girlfriend's bikes, but by the end of 1000Ks, I had lost my gears and both her and my friends bike were running out of brakes !!! In the end, it took us 13 days.
I am not trying to put you off, trust me, the 3 of us said we would ride this route again !!!
One last question, are you going to follow the road or the track? We followed the track and it is very well marked, the only problems we had were going through a national park after the Roman dam out of Merida, leaving Salamanca and Zamora as the markings were quite crappy. The 3 of us did have bike GPS units and if you want, I can email you this file
If you would like to see the ride, you can view the GPS here -

I am still in the process of writing my blog, but once done, I will post the links to the stories and photos
If you need anymore, just ask !!!
