J'ai testé le gr 169 il démarre d'Irigny et se termine à Feyzin
compter 170 km et 2100 m D+ je recommande pas , de petits chemins sympa, mais entrecoupés de petites routes et surtout passage dans le centre des communes, je pense que c'est voulu !
Le plus intéressant est entre Charbonnières et Cailloux sur Fontaine, cela permet de trouver des passages pour des retours ou des liaisons c'est bien le seul intérêt.
Le groupe Gravel Lyon l'effectue également, cela passe hormis quelques escaliers contournables.
Très difficile de suivre les balises (blanc/rouge) mal balisé et sans rappel, souvent par soustraction en rencontrant une croix ? j'ai les traces si cela vous dit
Voici un image ce tour des forts (12)
Maintenant tout sur la GTMC de Juillet probablement plus vtt
