Les courses du Carnaval is a morning running event in Dunkerque. The main race is a 21.1 km semi-marathon starting at 09:30. The programme also includes a 10 km race at 09:45, followed by two children's races: 2.7 km at 09:55 and 700 m at 10:00. This makes it a mixed race day, with adults, young runners, and families all using the same Carnival-themed meeting point.
The available course information focuses on distance rather than route detail. The clearest picture is of a compact local series built around the half marathon, a shorter road-race option, and junior runs. SEMI MARATHON DE DUNKERQUE organizes the event. A recent edition recorded about 900 participants, suggesting a community-sized race rather than a large city marathon.
