NEWS 2021 - in order to develop ourselves organizationally and to be able to make an even better offer in 2021, we will divide the Backwaterman into a SwimRun-Weekend and an Open Water-Weekend. This enables us to offer a supporting program on the one hand, but also new swimming routes, among other things are checked at the Dobra reservoir.


update: due to Covid 19 restrictions we postponed the event to 18/19th of September

Backwaterman 2020 SwimRun


supported by

15 year tradition
This is the Classic-open-water-long-distance-event with a distinctive flair in fjordlike waters of the Ottenstein reservoir north-west of Vienna.

The Backwaterman Waldviertel is the pioneer of the long distance open water scene since 2006. Jumping from the ship to get to the start of the race is legendary.


In addition to the traditional 7km race, there is also a 750m and 1.500m Open Water competition.

New for the 15th jubilee in 2021, the revival of the traditional 14k-race  will take place  and

a 3k distance is also added. 


Since 2020 an epic  SwimRun competition is offered in this unique nature.
