Test your resilience against the elements at L'Hivernale set for Sunday, 1st February 2026 in the preserved natural setting of the Étangs de Hollande in Yvelines. Organized by AESN 78, this authentic trail race offers two distances—a 24km at 9:30 AM and a 12km (open to Nordic walking) at 10:15 AM—on 100% forest paths where mud and frost may add to the challenge. The event emphasizes self-sufficiency, with no aid stations on course, requiring careful preparation to confront the winter terrain.
As the third stage of the Natura Trail Challenge, this race attracts runners seeking a raw, pure experience without changing rooms or bag drops, set within a protected natural area. It's the perfect opportunity to gauge your early-season fitness on a demanding course, where the only companions are the sound of your footsteps and the raw beauty of the winter landscape.
