[A CONFIRMER] Les Foulées Achéroises - 15 km 2026

Les Foulées Achéroises is a trail-running series in Achères, Yvelines, west of Paris, offering races of 5 km, 10 km, and 15 km, with shorter options available for younger or less experienced participants. The races begin in the morning, primarily taking place in nature rather than on roads. Forest paths constitute almost the entire route, with only brief road segments included. The 15 km course is the main event for those seeking a predominantly off-road challenge that isn't an ultra-marathon. Both licensed and non-licensed runners are welcome, and participation is limited to maintain the event's local character. Now in its 22nd edition, the event also benefits L'Etoile de Martin, an association supporting childhood cancer research and aiding hospitalized children.
