The Schloss Marienburg Marathon runs through the Calenberger Land around Nordstemmen-Adensen on a circular course made up of two laps laid out in the shape of a figure eight. The event is listed as a challenging landscape run, and the late November date means runners can expect soft, potentially muddy ground underfoot. A solo marathon, a relay and a walking category all form part of the programme, and the nearby castle gives the day its name. The 2026 edition is scheduled for 21 November.
