Trail Hivernal des Noct'en Bulles 2026

The Trail Hivernal des Noct'en Bulles is a winter evening trail run starting from the village hall in Sacy, with check-in prior to the 5:30 PM start. The course covers 15 km with 500 metres of elevation gain. It is intentionally not a competition; there are no bibs, no timing, and no official rankings. The objective is to run in the dark, share the experience, and support a local charity. A functional headlamp or chest lamp is mandatory; phone lights are not permitted. Participants must also wear reflective gear, carry a survival blanket, and have water-carrying equipment. This is the ninth edition of the event, with all proceeds benefiting AMOUR'RETT de LOUISE, an organization dedicated to improving Louise's daily life and funding research for Rett syndrome, a rare genetic disorder affecting young children.
