Coastal Marathon Otterndorf

The Küstenmarathon (Küstenmarathon Otterndorf) is a multi-distance running festival held in and around Otterndorf, Germany, with the 2026 edition scheduled for 20 September 2026. The programme covers a full range of distances from a 421 m Bambini-Lauf and Schülerläufe through 5 km and 10 km races up to a full marathon and a four-person marathon relay, plus a 21.1 km half marathon and a 25 km Jubiläumslauf. The event explicitly includes separate options for walkers, handbikers and pedalos, making it accessible to a wide range of participants and abilities.

Course routes pass along the Elbdeich, beside the water and through Otterndorf’s historic Altstadt, and the event runs a family activity area called "Kinderwelten" on the Kirchplatz (operating hours listed as 09:30–16:00). Official registration for the 2026 edition and the event Ausschreibung (online PDF) are linked from the organiser’s site, and separate pages provide course maps, results archives and service information such as arrival and prize-giving. The event is presented by the Küstenmarathon organisers in cooperation with local clubs and sponsors and combines competitive races with family-friendly activities and community features.
