La Tartencelloise is a 10 km foot race held around Margencel and Sciez, in a natural setting near the Chablais area of France. It is a traditional local event with a friendly, family-oriented feel rather than a race aimed only at fast club runners.
The event is organized by Association Reves d'Amazones, with support from Les Foulees chablaisiennes and the Foyer Rural. The day is built around running, local participation, conviviality, and solidarity, suiting runners who want a simple community race as much as a timed 10 km effort.
