SwimRun Trial Distance


The pivotal point is Ottenstein Castle, which offers a unique panorama for the start, finish, but also registration, award ceremony and race briefing in a medieval setting.


The participants over the sprint distance experience the core of the Ottenstein reservoir in the immediate vicinity of the dam.


Five running and four swimming sections offer a lot of variety.


2023 offers a complete redisign of the route with new trails and new perspectives.


Start and finish in front of Ottenstein Castle is definitely a unique experience. The natural trails, the Lichtenfeld ruins, some power places and wonderful views arise along the whole route.



The start is on Sundaz at 9:30   a.m. together with all other distances.


The race briefing takes place interactively on Saturday at 4 p.m. via Facebook Lifestream on the Backwaterman Facebook page. The briefing is then available as a video. The interactive race briefing is on all rules and pointers

to be observed as mandatory!


The  route can be mastered both individually and in a team.



The water temperature at the Ottenstein reservoir is 22 to 25 degrees. The latest information and guidelines on clothing (neoprene ban, etc.) are available at least 1 week before the competition.


Route marking: Unfortunately, you have to expect people to remove the route markings. For this reason, more emphasis is placed on triple marking with tapes, floor markings and signs. In addition, a graphic representation of the next route section is available for each route section.


Please be aware of our mandatory rules !
