NEW for 2026!
Something very special is coming to Llyn Brenig…
For the FIRST TIME, there will be an open water swim event in this incredible lake — and it’s exclusive to Love SwimRun.
Introducing The Big Brenig Swim
This is the only opportunity each year to swim across Llyn Brenig.
As a working reservoir, swimming isn’t normally allowed (apart from a very limited area for short supervised swims) making this a truly rare experience.
And we’re keeping it special…
🔥 Limited to just 300 swimmers 🔥
Choose your distance:
🏊 500m
🏊 1km
🏊 2.5km
🏊 5km
Whether you’re taking your first steps into open water or chasing a bigger endurance challenge, this event is designed to be:
💙 Inclusive
🤝 Friendly and welcoming
🌿 Eco-conscious
🛟 Safe and professionally supported
And of course, every Love SwimRun event comes with the touches you love:
🪨 Handmade Welsh slate medal
🍌 Tribe bar and snacks at the finish line
📸 Free event photos
Set in one of Wales’ most beautiful, wild, bodies of water, the 4th largest lake in Wales, rich in wildlife and normally off limits, this isn’t just another swim event…
It’s a rare chance to be part of something historic!
✨ Be amongst the first ever to swim The Big Brenig Swim. 🏅
