Cross Duathlon du Prunellu is a seaside cross duathlon held in Porto-Vecchio, Corse-du-Sud, Corsica. It takes place around late March and features a Duathlon S format, where athletes complete chained efforts instead of a single continuous race.
The location contributes to its appeal, utilizing a natural seaside environment that provides an outdoor island atmosphere distinct from road-only events. The event also includes children’s and junior races, with individual youth options available across various distances, ensuring participation is not limited to adults.
