Course du marais - Saint-Omer 2026

The Course du marais is a Saint-Omer running event held at 32 rue de la Poissonnerie, near the town’s marshland. Adult participants can select between 5 km and 10 km races, accommodating those aiming for a personal best and those seeking a local, accessible run. The schedule features children’s races, with distances ranging from 350 m to 2 km based on age. Families may also participate in a 5 to 7 km walk through the marsh, with proceeds benefiting UNICEF. Now in its 12th year, the event has established itself as a local tradition.
