About the race
Trondheim Maraton is a weekend running event in Trondheim, Norway, scheduled for 5 and 6 September 2026. The event is organised by Nidelv IL and Bedriftsidretten and takes place each year on the first weekend in September. From 2026 the main race day is on Sunday, while Saturday is a dedicated family day with Barnas Minimaraton and other children and family activities.
The event programme includes several race formats and team classes, and the organiser published a course map and race categories. The 2026 programme is presented alongside training resources developed with the partner LØFT din helse, which provides training plans for 5 km, 10 km and half marathon, plus strength programmes including sessions for runners without weights.
Registration is binding and non-refundable under consumer rules. It is possible to change distance up to the race day provided there is space; distance changes can be done online via the participant portal until bib distribution starts, after which a physical change is required.
The event noted 14 623 participants in the latest edition and states a focus on developing capacity, race and spectator experience, and a stronger family concept toward 2030. Visit the organization's website for the most recent information.
