About the race
Trondheim Maraton is an annual running festival in Trondheim, held the first weekend in September. The 2026 event takes place across two days: Saturday is a children and family day, and Sunday is the main race day in the city center.
The program includes multiple distances and race formats:
- 5 km
- 10 km
- Half marathon
- Marathon
- Team relays and children’s races
Several of the listed races use a certified C-measured course. The event is organised by Nidelv IL and Bedriftsidretten and combines competitive races, team events and family activities in Trondheim’s central area.
Trondheim Maraton collaborates with LØFT din helse to provide training plans and strength programs. Available materials include plans for 5 km, 10 km and half marathon training, plus strength sessions for runners and programs without weights.
Registration is binding and start-place purchases are not refundable. Distance changes are allowed up to race day if there is available space; changes can be made online until start number distribution begins, after which a physical visit is required to change distance.
