Semi-marathon Cancale Saint-Malo 2026

The Semi-Marathon Cancale Saint-Malo is a 21.1 km road half marathon in Brittany, run in late August from Cancale to Saint-Malo on France’s Côte d’Émeraude. It is the largest half marathon in Brittany, with about 7,000 runners, and it is a city-to-city seaside race rather than a loop around one town. The route follows the Emerald Coast past beaches, with Saint-Coulomb situated between the start in Cancale and the finish in Saint-Malo. Race listings describe it as a course for records, attracting runners seeking a fast half marathon. The event is heading for its 37th edition, and local write-ups treat it as one of Brittany’s older big running fixtures, complete with the playful image of a half marathon “in a sailor’s jacket.”
