Köln Triathlon 2026

The Köln Triathlon takes place in the city center of Cologne, typically in September. The swim is in the Rhine River, the bike course utilizes the autobahn and riverbank, and the run offers views of the Cologne Cathedral. Distances include middle, Olympic, and sprint, with relay options for middle and Olympic distances, allowing for varied levels of participation. The course is flat and fast, covering both sides of the Rhine. Participants will see or pass through much of central Cologne, including the Rhine, Rheinauhafen, Hohenzollernbrücke, Deutzer Brücke, Severinsbrücke, Rheinpark, Kölnmesse, Tanzbrunnen, and the cathedral. Organizers describe it as a classic event with a straightforward yet effective format: swim in the river, cycle on roads usually open to traffic, and run through the city with the Cologne Cathedral prominently visible.
