Steep climbs, technical terrain over 12 or 16 km… and all of this in the dead of night! Strap your headlamp on tight, because this trail is no joke. Hidden roots and steep slopes will put you to the test, as you weave between the trees and brush past the old quarries of Cousolre. One thing is certain: you're going to have to give it everything you've got!
What you'll find on site:
Course focus:
Whether you choose the 12 km or the 16 km, you'll immerse yourself in the valley of Cousolre in the most intense way possible: in the dead of night. The steep climbs will wake up your thighs, the technical descents will test your clarity and balance, while the forest sections and the edges of the old quarries will give the course an almost mystical dimension.
