FAQs

Gather a team of between 1 to 12 swimmers and swim for up to an hour each, for 12 hours!

This event is unique because it’s for everyone, regardless of your ability. It’s not a race so it’s not about speed or distance. You swim as much as you want, as fast as you want.

The challenge is the team work and camaraderie, supporting each other throughout the night. It’s the 2am cold swims when you just want to sleep. It’s the hugs of relief at the end of each hour. It’s cheering the sunrise.

It’s knowing that you’re doing it to raise money for Level Water who provide 1-to-1 swimming lessons for children with disabilities. It’s knowing that the power of your swimming is changing lives. And that’s pretty wonderful.

Described (by one person) as ‘the Glastonbury of swimming’. Swim Relays are a magical experience, you’ll want to come back to again and again.

The Atmosphere

It’s always a great atmosphere. The event staff maintained their energy throughout which helped when we were flagging!
Cheer the night

I loved the camaraderie, with people cheering on everyone, even at 2am. The people (staff and swimmers) were all so lovely and it's such an incredible community to be part of - watching everyone going in for that last hour made me emotional! The night swims were my favourite moment as it was so magical and unlike anything I'd ever done before.
The Glastonbury of Swimming

It felt like a swimming festival, like a Glastonbury with open water rather than bands. The community spirit really made it something special and all level waters staff really made it an event I’m looking forward to doing each year
Unique & Personal

The atmosphere was brilliant. The event itself is unique in being a personal/team endurance challenge rather than about speed or distance and although a few teams clearly wanted it to be competitive, the LW team was fantastic in promoting the inclusive, not a race message. The night time swims really are so special but also getting to swim as a team together was brilliant.
Such a Joy

The event weekend was such a joy to be a part of - seeing all these people come together to do something uplifting and for such an amazing cause creates the best buzz. It's so relaxed and easy going, everyone knows where to be and when, and it all just runs so smoothly. Sitting on the benches having a coffee after a 4-5am swim had to be the highlight.
A Glorious Sunrise

I enjoyed the way the swims were organised, 10 mins before the hour and you can start the changeover, it was nice and smooth. The uniqueness is the 12 hour part, I think its amazing. My personal favourite moment was my 5am - 6am swim with the GLORIOUS sunrise, a ball of yellow gold reflecting off the water. A few of us, including the safety guy on the kayak, just stopped to soak it all in. And before my last swim after i had “hit the wall” with exhaustion and tears, my team mates, our kids and families all had a 30 second dance party to get me ready for the last swim.
A fantastic event
