I solo-walked from Lourdes to San Jean Pied de Porte last July (2015).
It took 7 days walking and six overnights in Albergues / their French equivalents - Overnights: 1 Asson 2 Arudy 3 Oloron-St-Marie 4 L'hopital Saint Blaise 5 Mauleon 6 Saint-Just Ibarre
The route is very well marked as the GR78 but I would advise checking the evening before the route out of Lourdes and the route out of Arudy.
There tends to be some main-road walking (occasionally) so be careful - there are not many walkers, I found the last three days unbelievably quiet, at times lonely and character forming
I would advise using the link
http://vppyr.free.fr/vpp-index-etapes.php Paste the relevant pages into a word document and then use Google translate and print out the translation - its a bit
dodgy in places but I generally found the translation very useful.
I also bought
Sur le chemin de Saint Jacques de Compostelle (Lepere and Terrien 2013) - in French but you could pay to have the relevant pages translated or work on them as a project - by and large bang up to date - They also email you a list of updates upon purchase of the book
- be careful in Asson and Saint J-I - there are NO services.
Its a very quiet route with very friendly people (when you meet them). Finding the Albergue in Mauleon (Beautiful town) is an adventure and its hard to believe the contrast between Saint J-I and SJPP - despite being 25K apart.
I once had an issue with a dog and there was a lot of walking in Oak forests - there were also magnificent views.
If anyone has specific questions I will answer them as best I can - there is also a lot of other material on the forum so do search....
