L'enfer du viroin
A whole day playing with your limits. Big elevation gain, technical trails, and not a single meter to hide. Prepare your pack, your legs, and above all your mind, because you might just wonder what on earth you're doing in the Hell of the Viroin.

La descente aux enfers
A marathon format, wild version. Sublime landscapes, quad-shredding descents, and single-tracks as beautiful as they are ruthless. The only way out is to dig deep, descending further into your soul to find that last bit of strength.

L'infernale
The ultimate treacherous format. Not short enough to explode, not long enough to save energy. When the slope rears up, when your quads are already burning and the rocks join the party, you either push on or you walk: that's the dilemma of L'Infernale.

La maudite

La diabolique
Pure high-octane racing. The pack starts fast, the climbs are steep, and it's a relentless rhythm on the single-tracks. A concentrated dose of trail running that will keep you in the red from the first to the last kilometer.
L'échappatoire
A real bite of nature with just enough incline to warm up your calves and get a taste of the trail spirit. L'Échappatoire is the perfect gateway... or not.
