About 24-Hour Marathon Gronau

The 24-hour marathon in Gronau an der Leine isn't about a classic marathon course, but a very special endurance feat: for a day and a night, runners are active on a circuit around the Schützenhaus (marksmen's club house). Organized by the Schützenverein Gronau Leine, the event combines sporting ambition with a true festival atmosphere. Individual starters, relays, and hobby teams from the southern Hildesheim region compete against each other, while spectators, helpers, and families follow the action around the clock. The event is one of the best-known sporting events in the town of Gronau.

24 Hours of Running in the Leine Valley

The 24-hour marathon in Gronau offers a special mix of sport and folk festival (Volksfest): while the runners complete their laps, catering stands, music, and illuminated tracks create an atmosphere that goes far beyond the usual sporting event. During the day, runners enjoy the sunshine; at night, headlamps and floodlights accompany the athletes – a sight that fascinates many spectators.

Format for Individual and Team Runners

The event is open to ambitious individual starters who want to complete as many laps as possible, as well as relays from sports clubs, companies, or groups of friends. Within the 24 hours, every lap counts; individual teams coordinate among themselves who runs when. Catering, medical services, and rest areas are available at the Schützenhaus, making it possible to get through the night.

Gronau, the Leine Uplands, and the Schützenverein

The town of Gronau an der Leine is located on the western edge of the Hildesheim district and serves as the gateway to the Leine Uplands (Leinebergland). The Schützenverein Gronau Leine is one of the most traditional clubs in the region and has made a name for itself over the years through its broad range of sports and event activities. The Schützenhaus grounds on the outskirts of the town provide the fitting environment for an event of this magnitude. The 24-hour marathon attracts runners from all over southern Lower Saxony every year.

24-Hour Marathon Gronau — edition 2026

The 24-hour marathon organized by the Schützenverein Gronau Leine starts on Saturday at 10:00 AM and ends on Sunday at 3:00 PM.

From the Starting Signal to the Night Stage

The marathon is designed so that each participant can find their own rhythm within the 24 hours. While individual starters work with long break strategies, relay teams alternate at shorter intervals.
