Oooooh, I'd never even heard of that. Looks amazing! Hope the weather is kinder to you (slightly obsessed by mountain weather after this weekend!)

You're not the only one! Kinda crazy as it has 18 races over a weekend with nigh on 15,000 trail runners showing up. I believe it's one of the oldest races in France. It's in the South of France but well into autumn so we'll see & the area can get snow so we'll see.
