The Duathlon Ducs et Duchesses in Saint-Genix-les-Villages is an April duathlon held in Savoie, France, centered on Saint-Genix-sur-Guiers. The format is straightforward and demanding: run, bike, then run again, with continuous timing during transitions and no external assistance permitted.
The Saint-Genix race is part of the Ducs et Duchesses series organized by Savoie Sport Organisation, featuring four events in its fifth year. The competition includes M and S categories, an Animathlon for children aged 6 to 13, and options for solo, duo, relay, or team participation (two or three members). Bib collection takes place at the Salle Polyvalente on Route de la Gliere, contributing to the event's local, community-based atmosphere.
