The Duathlon du Mans is a late-winter run-bike-run event held in Le Mans, Sarthe, Pays de la Loire. It is centered at Stade Marie-Marvingt and offers race formats for adults and young athletes. These include S Open, licensed S races, XS youth races, and youth categories for ages 6-9 and 10-13. The S distance covers 27.5 km, and all races are open to para-sports categories.
The run segments are located around the stadium. The bike leg follows an out-and-back course near the Bugatti circuit, providing a distinct Le Mans motorsport context for the duathlon. The youth S and XS races act as a selective quarter-final for the French Youth Duathlon Championship. Several youth formats also contribute to the Pays de la Loire regional championship for licensed club athletes. Licensed and non-licensed participants can enter the S Open and youth races. Drafting is permitted in all formats except S Open.
