Semi Marathon Boucle de Seine

Join us for the inaugural edition of the Boucle de Seine Half Marathon, an official and measured race set to take place on March 21, 2027. This stunning 21.097 km course will wind along the picturesque banks of the Seine River, offering runners a unique glimpse into landscapes that inspired some of France's most celebrated impressionist artists. Starting at Île des Impressionnistes in Chatou and weaving through charming towns like Le Pecq and Croissy-sur-Seine, participants will enjoy breathtaking views of historic homes, lush parks, and the serene waters of the Seine.
The race begins promptly at 9:00 AM from Île des Impressionnistes. For security reasons, each runner is allowed to bring only one small bag, which must be clearly labeled with their race number for collection after the event upon presentation of that same number. Runners have the option to receive their bibs by mail before the day of the race if they complete all required documentation.
The top three male and female finishers will each earn a trophy and monetary prizes: €800 for first place, €400 for second, and €200 for third. All participants can look forward to receiving a commemorative medal upon crossing the finish line.
Immerse yourself in this scenic half marathon that celebrates both athletic achievement and artistic heritage along one of France's most picturesque waterways.
