The Semi-Marathon Cancale Saint-Malo is a major annual running event on France’s Côte d’Émeraude, celebrating its 37th edition on 23 August 2026. The 21.1-kilometre race is expected to bring together 7,000 runners and is recognised with a Bronze label from the French Athletics Federation. Its scenic route starts in Cancale, passes through Saint-Coulomb and finishes in Saint-Malo, combining coastal views with a challenging course featuring 166 metres of positive elevation.

The event offers individual registration and a corporate team challenge for teams of four, with company entries priced at €200. Participants can access practical race information, including route details, parking, shuttle services, bib collection and results, as well as photos and videos. The organisers also invite people to volunteer and provide partnership opportunities for businesses seeking visibility among runners and local audiences. A race expo associated with bib collection attracts more than 10,000 visitors on the day before the event.
