Long distance marathon 14 km


The marathon distance has been an international flagship since the beginning and was suspended for 2 years after being held 12 times. For the anniversary there is now a revival for our long distance specialists. The route leads from the Ottenstein boat company to the start of the 7km to Mitterreith and back again.


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.


Attention: Due to the increased safety requirements, it is mandatory to be accompanied by an e-boat and your own supervisor.

There are 15 e-boats available and can be booked at the special price of € 25. This is already included in the registration price.

The e-boat can be replaced by your own kayak (attention no SUP allowed). This increases our starter capacity. In this case, the e-boat price of € 25 will be refunded upon registration.


Note: For safety reasons, the e-boat may only be escorted from km 1, ie the first headland.

The total limit of the 14 km distance is 20 participants.


A buoy is recommended and can be borrowed for free.


The 14 km Backwaterman also count in the rating system for the Austrian Open Water Majors.
