RuM Rubbenbruchseemarathon

Rubbenbruchsee Marathon (RuM) is a running event based at the Rubbenbruchsee in Osnabrück, Germany. The website describes the marathon as taking place on the second Saturday in December, offering runners an opportunity to race beyond the usual season and enjoy a winter event that may bring cold, slippery, or wet conditions. RuM welcomes participants with different motivations, from those seeking a December challenge or preparing for the next year to runners aiming to complete their collection of RuM medals.

The event’s online resources include race announcements, participant information, frequently asked questions, news, and practical details. Visitors can also explore results, lap times, a Hall of Fame, photographs, press coverage, statistics, and retrospectives from past editions. The archive documents events from the inaugural 2014 race through the tenth edition in 2023.

The site provides links to running portals and recommended resources, along with information about donations and a stated €10 cashback offer for running the event. RuM combines a seasonal marathon with a record of its runners and event history
