Hi, anyone ever toured on one of the Grande Randonnées or other long distance trails? Know of someone who did? Know of an organization or tour company you can refer us to?

We did one of the Grande Randonnées in the Lot Valley and really enjoyed it. Even though it's legal to bike on most of them, they're not always bikable. But since this is not a very popular activity, it's proving impossible to find information on which of them (or other long distance hiking trails) are bikable. I've searched everywhere! Thanks for any help!
