Registration from 1st of November

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

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, and the power of the competition.
