Trail les 3 Bois is a 15 kilometre trail race staged in Port-Jérôme-sur-Seine, a town on the Seine in the Seine-Maritime department of Normandy. The route is run on the wooded paths around the town, the three woods that give the event its name, and it is a single-distance race with one start. Race day is Saturday 12 December 2026, so runners should expect a mid-December Normandy winter and dress for cold, damp ground underfoot. Entries and the latest race information are handled through the organiser's website, which is the best place to confirm details before travelling.

The race is scheduled for Saturday 12 December 2026.
The route is a trail course through the wooded country around Port-Jérôme-sur-Seine, the three woods that give the event its name. Expect soft, uneven woodland paths rather than tarmac.
The race is run on woodland trails in mid-December, when Normandy paths are often muddy and slick. Trail shoes with decent grip are the sensible choice, along with layers you can adjust as you warm up.
No weather policy was published here. Winter events in Normandy are usually run in rain and cold, but for anything severe you should check the organiser's website on the day before travelling.
