Cologne, Germany · Tuesday 6 October 2026
Cologne's marathon takes runners through the heart of the city, starting in the Deutz district and finishing at the iconic Kölner Dom. The race winds through some of the most characterful neighborhoods in the city, passing through Rodenkirchen, Lindenthal, Ehrenfeld, and Nippes as it travels from the Rhine toward the cathedral. Running through these lived-in districts means you'll experience the real rhythm of Cologne rather than just its postcard landmarks, with local supporters lining the streets and the architectural texture of the city revealing itself mile after mile. The course is refreshingly straightforward: flat to gently rolling terrain without any serious climbing to speak of. At roughly 101 meters of elevation gain across the entire distance, this isn't a route that will test your hill fitness, which makes it ideal for runners chasing a time or simply wanting to focus on pace without fighting gravity. The trail surface keeps things consistent underfoot, and the gentle undulations work in your favor as much as they test you, creating the kind of course where effort translates fairly directly to performance.

Generali Cologne Marathon is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths.
