18. swb-Marathon Bremen
Bremen, Germany · Thursday 1 October 2026
The swb-Marathon Bremen takes place on September 13, 2026, on a flat to gently rolling trail course that winds through the city's best areas, starting and finishing on the Marktplatz. The 42.2km route showcases Bremen's landmarks including the Werdersee, Weserwehr, Rhododendron-Park, and finishes with a lap through the Weserstadion before returning to the market square. With only 174 meters of elevation gain and maximum heights around 20 meters above sea level, this is a course built for steady running rather than climbing. You'll run on trail surfaces throughout, which means softer underfoot conditions than typical road marathons. The event is well-established, now in its 21st edition, so expect good organization and crowd support along the way, particularly at major landmarks and the stadium finish.
