Le Semi D'istres 2026

Le Semi d’Istres is a road race held in Istres, located in the Bouches-du-Rhône department of southern France. It takes place in late November and features two race options: a half marathon covering 21.1 km and a 10 km race. The half marathon begins at 09:00, followed by the 10 km race at 09:30. Registration fees are set at 33 EUR for the half marathon and 13 EUR for the 10 km. This positions the event as a straightforward race morning with two distances, rather than an extensive multi-format festival.
