Boucles dunkerquoises takes place on a September race day in Dunkirk, located on France's North Sea coast. The event offers road running distances of 20 km, 10 km, and 5 km. Additionally, there is a 5 km walk and several children's races, catering to individuals seeking a longer run, families, and those preferring a brief excursion by the water.
The course primarily follows the Dunkirk seaside, providing views of the port city's waterfront and, under favorable conditions, glimpses of the large cargo ships navigating the harbour. Recent participation has neared 3,900 individuals, lending the event the atmosphere of a bustling local gathering rather than a small club competition. The children's races are divided into short distances, ranging from under 1 km to 1.8 km, contributing to a morning that resembles a comprehensive community race schedule.
