Breaking news




We are proud to host the


  • European Championships Half Distance for teams and solo in 2023 as part of the My SwimRuun Championships.
  • We will also host the European Championships over the marathon distance for the solo competition.




This also requires an accompanying program for us that we will upgrade additionally.




Attention: The half marathon course remains unchanged.


In order to enable the marathon participants to take part, the marathon route is led through the half-marathon finish, where the time is taken (and thus helped to be counted for the championships) and then leads into the extra marathon loop so that the marathon can be finished normally.


This results in a double ranking half and marathon for the marathon starters. The route plans and dates for the marathon will be adapted over the next few days.



Discover the best SwimRun sceneries of Europe 
discover the fjord-like landscape of the Ottenstein reservoir and 'Be a Backwaterman'
Embedded in the Kampseen you can expect unique views of the lake landscape combined with the peace and power of the Waldviertel, 
as well as a varied series of forest and forest paths with trails and nature trails .
The swim offers everything from open water feeling, rocky or sandy exits. Some of the meters in altitude can be managed right after the exits, 
so the running routes are often pleasant to run.
In 2023 we redesigned most of the routes. It begins with a round in the castle park and soon the views of the reservoir open up. 
The swimming portions are shortened and more running portions, which will make the course faster.
