The Duathlon de Saint-Dié-des-Vosges uses the Géoparc, a motor-racing circuit in Saint-Dié-des-Vosges, Grand Est region, France, for its run and bike legs. Organized by Triathlon Club Déodatien, the event focuses on short-format duathlon rather than a long road course. It typically aligns with early-season racing and offers adult categories (S and XS) alongside youth races for participants as young as six. Fields often approach 350 starters, creating a competitive atmosphere akin to a local club event.
The Géoparc circuit defines the race setting, providing a controlled, closed-course environment for the bike segment. The youth program features short distances, with the youngest categories completing a 0.3 km run, 1.25 km bike, and 0.3 km run. Close finishes are common; one main race saw Théo Weber narrowly beat Noé Weber for first, with Loïc Menoux in third, while Laura Bontemps secured a clear victory in the women's race. The XS race has also highlighted local talent, such as Basile Mathis and Martin Boito from Gérardmer taking the top two spots.
