Swimmers in warm open water at an UltraSwim 33.3 event in Greece

Fundraising

Be inspired, by the Olympics, and by Léman hope!

Join us for a very special evening at the world famous Olympic Museum in Lausanne on Sunday 26 July 2026. Celebrate what will have hopefully been an epic crossing of the lake - and do it for a great cause, our official charity Léman hope. As soon as the final official swim briefing is complete (also to be held at this location), enjoy exclusive after-hours private access to the fantastic Olympic Museum's exhibits, followed by a food and drinks reception in this spectacular setting overlooking Lac Léman. Hear from our charity partner about the inspiring work of Léman hope, which uses 5 day long sailing trips on the lake as a therapeutic tool to help children in remission from cancer rebuild their confidence after what is often many years of brutal and disruptive treatment.

WORRIED ABOUT BEING TIRED AFTER THE BIG MARATHON SWIM DAY?

Well everything in perspective when you hear about the young cancer survivors’ stories - and its shortest swim of the event on the Monday morning…no excuses!

WHY NOT MAKE THIS YOUR PERSONAL CAUSE?

If you are not already swimming for a charity in Switzerland, you can set up a personal fundraiser nd help us reach our target of 33,333 CHF in support of the Léman hope! You can donate directly here also, as well as set yourself up as a team member and use the page to inspire your own network back home to support your efforts.

All our events so far have won awards. See reviews from other swimmers.
