25h-Lauffestival Göttingen

The 25h-Lauffestival Göttingen is a September road-loop race in Göttingen, Germany, centered on a main event lasting 25 hours. Held in the Jahnstadion sports park, participants repeat a 1,100-meter lap rather than running through the city. Solo entry costs 30 EUR, and the event is organized by Göttinger Sport und Freizeit GmbH & Co. KG. The loop is nearly flat, with 1 meter of elevation gain per lap, and the surface alternates between asphalt, tartan, and wide walking paths. The program also features a 25-hour team relay for up to 25 runners, a 25-hour Extreme event for up to 25 runners, and a 6-hour children's race for ages 6 to 15. It is listed in the DUV ultramarathon database without an IAU label, and its results are not marked as eligible for other ultra races in Göttingen.
