Backwaterman SwimRun

Half Marathon


 This final edition is not meant to be a quiet farewell – but a celebration for everyone who was part of this story.

And it will be a Big Bang Farewell with the organization of the My SwimRun World Championships Marathon.

We want to dive in with you one last time – into the adventure, the silence of the lake, the power of competition.

Motto: Enjoy the LAST ONE
