The Semi-marathon de Joinville is a road race held in Joinville-le-Pont, Val-de-Marne, near Paris. The primary event is a single-loop half marathon covering the official 21.0975 km distance, typically scheduled for late March. The event also features a 10 km race and a family Color race, ensuring participation beyond just half-marathon competitors.
The course is set within the town and passes through a public park, offering participants a city-based route rather than a rural one. The half marathon is the most attended distance, with the 10 km race commencing later in the morning, followed by the family race. L'Athletique Club de Paris Joinville organizes the event in conjunction with the commune of Joinville-le-Pont. This series is relatively new, with its third edition planned.
