Semi-marathon et 10 km de la ballastière - Aire-sur-la-Lys 2027

La Ballastière offers a half marathon and a 10 km race in Aire-sur-la-Lys, a town in Pas-de-Calais, northern France. Both races begin at 10:00 from the Paul Nestier sports park on Avenue Carnot. A 10 km Nordic walk starts two minutes later. OSA Athlétisme organizes the event, which follows a simple local format: one start, three options, and distances suitable for half-marathon runners or those seeking a shorter morning run. The half marathon is the standard 21.1 km. The 10 km running race and Nordic walk also cover 10 km. Bib pickup is available the day before at Intersport Arques and on race morning at Stade Nestier in Aire-sur-la-Lys, where late registration is possible for a small fee. Non-licensed adult runners require a valid PPS attestation. Minors who are not licensed must complete a health questionnaire.
