Support the swim
How can you help?Working together for a clean Danube
and a unique adventure
There are two ways to support the 2026 Danube Swim:
You can either support our swim team directly or contribute to scientific research.
Support for the swim team
Support the 2026 Danube Swim directly and help our team along the entire length of the Danube.
Please make a symbolic donation to buy us a cup of coffee, a meal, or a tank of gas for the support boat and logistics. Every contribution helps make this adventure possible.
Support science
The Danube Swim is more than just an extreme sport: Together with research partners, we are studying microplastics and water quality along the entire length of the Danube.
If you'd like to support this research, you can donate directly through Betterplace.
