Seine-Eure Marathon 2026: Marathon, Half Marathon, Ekiden

The event "Marathon Seine-Eure 2026 : Marathon, Semi-marathon, Ekiden" brings three flagship races together on a single day in the heart of Normandy, finishing in Val-de-Reuil. Organised by the Association Marathon Sport Événement, the edition is presented as the 21st running of the event and the organiser confirms registrations for the 2026 edition will open on 1 February 2026. All three races are run on strictly identical parcours to recent editions and the website highlights detailed course maps, shuttle information and service pages for participants.

The three-format programme includes a full marathon, a half-marathon and an Ekiden team relay (six legs) and is promoted for its flat, river-side course through several Eure communes. Practical information pages on the official site cover regulations, medals and prize lists, village layouts, accommodation and logistics so entrants can consult race-specific registration pages. Contact details for the organiser ([email protected]) and capacity limits per race are published on the official edition pages for planning and eligibility checks.
