Bike Challenge

The Bike Challenge (Bike Challenge Mittelholstein) is a large Breitensport cycling festival organised by RSG Mittelpunkt Nortorf v. 2005 e.V., bringing together road and gravel riders around Nortorf. The event day combines a long Radmarathon route with multiple granfondo-style and gravel options, digital route downloads via Komoot and a dedicated digital start map to help participants navigate the courses. Safety and courteous shared-road behaviour are emphasised throughout; the organiser explicitly describes the rides as non-competitive tour rides that follow traffic rules and respect pedestrians.

Organisers publish multiple distinct route profiles covering both paved and mixed-surface courses, including dedicated gravel variants, with route files and elevation data available on Komoot. Riders start from the Kramer-Scheune (Heinkenborsteler Weg 8) and can choose among several distances from shorter fondo options up to the full Radmarathon, with refuelling depots located at Aukrug and Kellinghusen. The event is promoted via the official Nortorf event pages and linked Komoot route maps; exact start times and final route files are published shortly before the event to reflect any official approvals and may change pending permits. Participants are advised to download the final route files shortly before the event and to consult the official Nortorf event page for any late updates or logistical details.

The event is listed as part of regional Radmarathon series (Part of NordCup-Radmarathon and Part of Radmarathon Cup Deutschland).
