Semi-marathon des Lions

The Lions Half Marathon (Semi-Marathon des Lions) returns to the scenic banks of the Seine in Rueil-Malmaison on Sunday, April 12, 2026. This 100% charitable event, organized by the Lions Club of Rueil-Malmaison, offers runners a high-quality sporting experience while directly transforming lives. All profits from the race are dedicated to solidarity actions, supporting major causes such as disability sports, childhood cancer research, vision health, and local social initiatives like the Rueil-Malmaison social grocery store. Whether you are using this as a marathon warm-up or enjoying a morning run with friends, every kilometer run contributes to meaningful social impact.

Training and Preparation

To help participants reach their goals, the event offers free training sessions in collaboration with Xrun Rueil. Registered runners can join coached sessions every Thursday evening at the Jules Ladoumègue stadium, guided by running coaches and physical therapists. These sessions include VMA testing and specific race-pace training. Additionally, partners like Terre de Running Puteaux provide specialized equipment support for participants. By combining athletic preparation with a deep commitment to community welfare, the Lions Half Marathon stands as a premier inclusive sporting event in the Paris region.
