L'Allingeoise takes runners into the hills above Lake Geneva, starting from Allinges in Haute-Savoie. The first trail begins at 7am, with a family walk scheduled for later in the morning. Participants can choose from four options: the 42km Trail des Belvèdères, the 21km Trail L'Allingeoise, La Ronde des Châteaux, and the Marche des Familles.
The 42km route involves an 1800m climb, the 21km trail has 700m of ascent, and La Ronde des Châteaux climbs 415m. This offers a range from demanding trail running to a shorter option suitable for families or friends. The family walk covers a path similar to La Ronde des Châteaux, and all courses provide views of the Chablais region and Lake Geneva. The Lions Club and the Mairie d'Allinges organize the event, with proceeds benefiting associations that support children with disabilities.
