Roc d'opale - Calais

Roc d'Opale - Calais is a 12 km hike in Calais, Pas-de-Calais, northern France. Scheduled for early June with a 4 euro entry fee, it presents as an accessible local challenge rather than a large commercial event. The course is 12 km within Calais, reachable by public transport or car. The event welcomes both experienced runners and beginners. Visitors can explore the Cité de la Dentelle et de la Mode, a lace and fashion museum housed in a former lace factory in Calais.
