What is Swim4Lémanhope?
Swim4Lémanhope is a sports and solidarity event organized by the Fondation Léman hope since 2022. Through a collective swimming challenge, its mission is to raise funds to finance therapeutic cruises for children and teenagers in remission from cancer.
Every year, Swim4Lémanhope brings together employees and companies for a unique team-building experience with a strong human impact, in two emblematic Swiss locations:
- Lake Geneva, in French-speaking Switzerland on June 23, 24, 25 and 26, 2026
- Lake Zurich in German-speaking Switzerland on June 17, 2026
A meaningful challenge
Swim4Lémanhope is more than just a sporting performance, it's a human adventure: a time for surpassing oneself, solidarity and commitment. Every fathom counts - for the participants, but above all for the young beneficiaries.
Thanks to the funds raised, teenagers who have beaten the disease can embark on a Léman hope cruise: 5 days aboard a sailboat, to rebuild confidence, autonomy and hope in a caring and inspiring environment.
More concretely?
Joining the Swim4Lémanhope adventure means getting involved in a sporting challenge that's both accessible and supportive, in aid of children in remission from cancer. Here's how to embark on this unique experience:
1. Choose your group challenge
The crossing of Lake Geneva is divided into several 8-10 km relays.
Your company can choose one or more, depending on its level of involvement and its objective of contributing to the financing of Léman hope cruises.
Each relay involved funds a cruise for a child.
2. Build your swimming teams
Put together teams of 4 to 9 swimmers per relay. Each company can enter one or more teams, depending on its capacity and ambitions.
3. Each participant chooses their distance
In a relay, each swimmer chooses the distance they wish to cover: 200 m, 500 m, 1 km or more.
Everyone participates at their own pace, according to their level.
4. Go further in your commitment
In addition to the support provided by the participation fees, most companies choose to create a fundraising page on our platform.
It's a way of amplifying their impact, by sharing their challenge externally, mobilizing their ecosystem and giving even greater visibility to their commitment.
A great opportunity to unite people outside the company.
5. Plan your adventure together
Organize training sessions, create team dynamics and live the Swim4Lémanhope spirit. The power of teamwork starts long before the big day.
