The Hochsauerlandklassiker is a road-cycling RTF and radmarathon in Germany's Hochsauerland, with morning start windows that depend on the distance. Riders can choose 70 km, 110 km, 140 km, or a 215 km marathon route, ranging from a hilly club ride to a long mountain-heavy effort. Climbing is central: the shortest route has 900 meters of gain, while the 215 km option climbs 3,500 meters. Registration is on site, the GC Touren App is recommended to avoid paper forms, and payment is cash only.
The routes use control and refreshment stops around places such as Landenbeck, Schmallenberg, Klause, Kahler Asten, and Willingen. Kahler Asten is featured on the longer routes, and the 215 km marathon reaches it twice, indicating the ride's profile. The organizers recommend using the GPX file for the radmarathon route due to minor route changes. Riders are asked to bring their own bottles, as refreshment stops do not provide plastic cups to reduce plastic waste.
