Semi-Marathon de Lille

The Semi-Marathon de Lille is an FFA Gold-labeled half marathon through the historic center of Lille, in the Hauts-de-France region of northern France, with its next edition on Sunday, October 25, 2026. The race traces back to 1986 as a full marathon, converting to the 21.0975 km half-marathon distance in 1996 after hosting the French national half-marathon championships alongside its final marathon edition in 1995. The organizers describe the course as ultra-flat and fast, running through Lille's city center past the Citadelle de Lille with a finish near Place de la République-Beaux-Arts, and the men's course record of 59:05 (set in 2012) is the fastest half-marathon time ever recorded on French soil. For 2026, the Semi-Marathon de Lille runs for the first time as part of a revived TREK Marathon International de Lille weekend, which brings a full marathon back to the city after a 31-year absence alongside the half marathon and a 10K. Registration for the half marathon opened July 1, 2026 at 35 euros (platform fees excluded, free for licensed Hauts-de-France FFA athletes), and bibs sold out within weeks, well ahead of the official October 4, 2026 registration deadline; a resale platform is available for runners still hoping to get a bib. Finishers must complete the course within 2 hours 30 minutes, with a mandatory 15 km checkpoint cutoff of 1 hour 47 minutes.
