As far as I can tell everyone who has set off along the GR1 armed with a little blue book containing my description of the route has somehow survived the experience. Feedback suggests that, generally speaking, the sequence of events on the ground follows that described in the guide. The route, however, is 1250kms long, things do change and occasionally my description of the route has left hikers scratching their heads. Most hikers, following the recommendation in the guide, have used the GPS route (many using GPS for the first time) and the only real problems reported are from those attempting the route with just the guide.
The good news is that in a number of places the route has been improved. For much of its length, the GR1 passes through wild countryside and although populated in the recent past, the people who originally used the footpaths and maintained the tracks that make up the route have long departed. Keeping it open and preventing it from becoming overgrown relies on the efforts of local volunteers and the occasional smidgen of public money.
