5. O-CTF Winter Kartoffeltour 2026

The O-CTF Winter Kartoffeltour is a 46 km off-road cycling tour in Hannover, beginning at Stammestrasse 104 in the late morning. Organized by RSV Concordia v. 1909 Hannover e.V. under the Niedersachsen regional association, it is part of the Breitensport calendar, emphasizing amateur participation over competitive racing. Riders navigate using a GPS track, as the course is not fully marked. The route is described as wavy with approximately 190 meters of elevation gain. This event follows a brevet format, meaning there is no signposting or support service, though participants receive a route plan and control card from the club. This setup provides a self-reliant winter CTF experience for those comfortable with self-navigation around Hannover.
