24-Hour Underwater Relay: Greatest Distance with Breath Held (Team World Record Attempt)

🌊 WHAT’S HAPPENING?
We’re attempting a Guinness World Record that pushes the limits of breath-hold endurance, teamwork, and mental strength.
Nine elite freedivers will join forces in a 24-hour relay, swimming over 60 km underwater.
The discipline is Dynamic No Fins (DNF) — imagine an underwater breaststroke. No fins. Just lungs, mindset, and pure teamwork.

This is how it works:
- Continuous rotation — each diver swims 25m on a single breath, averaging ~25 seconds per lap.
- Each diver will complete 266–350 laps.
- Together, that’s 2,400+ underwater laps in 24 hours!
WHY THIS RECORD MATTERS
This attempt isn’t just about chasing a world record. It’s about showing the public the beauty of freediving — the calm, focus, and resilience it takes to master your breath.
And we’re doing it in support of Rainbow Club, a charity providing swimming and water-based programs for children and young adults with disabilities.
🫶 WANT TO BE PART OF IT?
We’d love your support! We’re looking for:
- Volunteers (judges, witnesses, media support, medics, videographers, photographers, general crew)
- Sponsors & partners who want to be involved
It’s going to be a one-of-a-kind event — and we’d love you to be part of the journey.
