Parc des Bords-de-Seine, Rueil-Malmaison, 92500, France
The Semi-marathon des Lions is a charity road race organised by the Lions Club de Rueil-Malmaison and scheduled for Sunday 12 April 2026. The event offers two distances— a 10 km race and a semi-marathon—along the banks of the Seine in Rueil-Malmaison, with a start/finish area near the Parc des Bords-de-Seine and Espace Renoir. The race is promoted as 100% solidary with proceeds directed to local charitable projects, and the organiser emphasises community beneficiaries such as handi-sport, school eye-detection programmes and local social initiatives. Registration for the 2026 edition is listed as closed on the official site.
Race-day logistics include staggered start times (10 km at 09:30 and the semi-marathon at 10:30), bib collection the day before and on race morning, and standard race services such as aid stations, changing/baggage facilities and chip timing. Free training sessions with partner Xrun are offered to registered runners, typically on Thursday evenings at Stade Jules Ladoumègue. The event page provides course maps, GPX traces, results and photos, and lists local partners including the Ville de Rueil-Malmaison and Terre de Running Puteaux. For detailed rules, medical requirements and exact course files consult the official event pages linked on the organiser site.
