The Classic Open Water 7 k 


The 7 km Backwaterman has been the most traditional long distance race in Austria for 14 years. The unique fjord landscape in the Ottenstein reservoir offers open water swimmers a pure experience of nature. The reservoir is only accessible in a few places and therefore invites you to discover it by boat, canoe and SUP. The journey with the MS Ottenstein to the starting point in Mitterreith is special.


Attention: The capacity of the ship is limited to 100 participants and will be allocated after registration.


The total limit of the 7 km distance is 100 participants.


Accompanying with a canoe is prohibited for safety and competition reasons.


We recommend a buoy system for non-club swimmers.


The 7 km Backwaterman are part of the Austrian Open Water Majors, the 3000 m part of the Volks Cup and the junior competitions are part of the Junior Open Water Cup.
