Die Grosse Weserrunde - Der Radmarathon entlang der Weser

Die Grosse Weserrunde - Der Radmarathon entlang der Weser is a multi-distance long‑distance cycling event held on 22 August 2026, organised by Stadtwerke Rinteln GmbH. Now in its 16th edition, the event is staged around the Weserbergland and emphasises a non‑competitive, communal ride rather than a race. Riders may choose from multiple routes ranging from 80 km to 350 km, each following scenic sections of the Weser and visiting a sequence of towns in the region. The start and finish have been moved back to Gymnasium Ernestinum Rinteln at Paul‑Erdniß‑Straße 1, 31737 Rinteln for this edition.

The event webpage and route pages provide detailed course information, route tracks and registration via the ticketshop, while practical items such as start times and full entry conditions are published on the organiser’s site. The event offers rider services including a pasta‑party and event merchandise (shirt pre‑order stated on the site), and the organiser reported around 600 registered participants in January 2026. Die Grosse Weserrunde is presented as a long‑distance cycling experience for riders of differing ambitions and is listed as part of the German Cycling RADMARATHON‑CUP 2026 on the official site.
