The Middle Distance in the City of Vikings

The Viking Triathlon Schleswig combines demanding endurance sports with the unique backdrop of a historic city in the state of Schleswig-Holstein. Located in the Schleswig-Flensburg district, Schleswig looks back on a Viking past: just a few kilometers away is Haithabu, one of Northern Europe's most important Viking settlements and part of the UNESCO World Heritage since 2018. This historical background is reflected in the event's name, logo, and overall communication.

Course and Disciplines

The 5th edition on June 21, 2026, will be held as the DTU German Championship Middle Distance Triathlon — a special honor for the still young event. The course follows a classic middle-distance format:

Swimming — 1.9 km in the Louisenbad on the Schlei: The open water of the sea arm provides Nordic conditions and is considered by many participants to be one of the most beautiful swimming courses in the German triathlon calendar.
Cycling — 90 km on a fast, well-maintained course along the B76 through the agricultural landscape of Schleswig-Holstein's Geest.
Running — 21.1 km as a half-marathon distance over three loops through Schleswig — past the baroque Gottorf Castle, the castle gardens, and along the Schlei riverbank.

Organizer and Background

The competition is organized by Sub4 Sportevents UG with managing directors Leon Schönknecht, Martin Müller, and Timo Petersen. Since its first edition in 2022, the Viking Triathlon has become a firm fixture in the middle-distance calendar and has reached a career highlight with the DTU championship allocation for 2026.

Set in a Special Region

Athletes and companions arriving in Schleswig will find not only a competition city but also a wealth of culture: the Haithabu Viking Museum, Gottorf Castle with the Schleswig-Holstein State Museum, St. Petri Cathedral, and the old town along the Schlei. The Schlei itself — Germany's longest fjord — provides the setting for the event and makes the competition weekend more than just a sports weekend for many.
