This trail only opened last year, and was inspired by the US Pacific Crest Trail. The creator (from Chamonix) quit his tech job and journeyed from South America to Canada, and while on the PCT wondered why doesn't France have its own grand mountain trail? So he and a few others planned this route, crowdfunded an app to consolidate its info (campsites, water sources) and came up with this. https://www.connexionfrance.com/article/Mag/Nature/New-3-000...
