Entre dunes et bouchots - Hillion 2027

Entre dunes et bouchots is a two-day trail-running event in Hillion, located on the Saint-Brieuc Bay peninsula in Brittany. The name reflects the local environment: coastal dunes and bouchots, which are wooden stakes used for mussel farming in the bay. The first day is dedicated to children’s races and activities, with the main trail races taking place on the second day. Runners can select from four distances: the 9 km Trail des Marais, the 14 km Trail des Guettes, the 27 km Les Hauts du Pont Rolland, and the 40 km Le Grand Tra Hillion. The two shorter races begin at the Hillion gymnasium, while the two longer races start from the port of Dahouet. Registration is exclusively online via KLIKEGO. A PPS health questionnaire is required for most participants, athletics licenses are accepted, and signed parental authorization is necessary for minors.
