Trondheim Marathon is Norway’s oldest city marathon, and in 2026 it returns on the first weekend of September, with the headline races scheduled for Sunday 6 September 2026. The programme includes a 42.2 km marathon, 21.1 km half marathon, 10 km (BDO-Mila) and 5 km (TrøndelagKraft 5ern), plus relays (Team Coop marathon and half marathon), a Kids’ Mini Marathon, Tobb Young 5k and para-sport categories, turning the city into a full running festival. The routes are entirely on asphalt, following a relatively flat profile that winds around the colourful wooden houses of the old town, crosses the Old Town Bridge and traces long stretches beside the Nidelva river and Trondheim’s harbourfront. Cool early-autumn temperatures and gentle elevation make it a good option for personal best attempts, while the scenery offers a mix of fjord views, historic streets and modern city sections. With thousands of participants and strong local support, it’s a showcase of pure “løpeglede” — running joy — in the heart of central Norway.
