This year we will follow the GR10.  It is a traverse of the Pyrenees, from Hendaye on the Atlantic to Banyuls-sur-Mer on the Mediterranean.  Daily blogs will file here.

The official GR10 website has lots of useful information, including all the gpx track data.  It can be found here:

We also bought the e-book version of Trekking the GR10 (Cicerone).  It’s generally good, though some of the links for accommodation take you to Chinese websites.  Some of the route descriptions are a bit garbled (especially if there is a variant on the day), and in one case the route described is now closed, and looked dangerous.
