Heidemarathon Stüde is a small German running event in Sassenburg-Stüde, Lower Saxony, starting and finishing at Eichenkamp. Participants can select a 10 km race, a half marathon, or a full marathon. A 10 km option is also available for walkers. The race begins in the afternoon, with registration via the organizer’s website. Electronic timing is managed by Laufmanager.
The course runs alongside the Elbe-Seitenkanal and incorporates a short 1.235 km loop within the town. Consequently, the longer races consist of repeated laps rather than a single point-to-point route. Marathon participants run 34 laps, half marathoners complete 17, and 10 km runners do 8. The marathon holds approval from the German athletics federation. Local Stüde running groups organize the event alongside 100MC Deutschland, contributing to its draw for runners aiming for official long-distance finishes and personal bests.
