About

A community built on water, wellbeing and connection

TriSwim is an award-winning open water swimming community offering safe, lifeguarded and deeply supportive swim experiences across Kent, Sussex and the Southeast.

Founded and led by mentor, teacher and coach Laura Ansell, TriSwim opens the door to water for everyone — from nervous beginners and aquaphobic swimmers, to competitive athletes seeking expert stroke refinement, video analysis and Swim Smooth–inspired coaching.

At our lakes, swimmers find clean, professionally supervised spaces to explore open water at their own pace. We provide a full programme of free safety introductions for children and their families, helping local communities build real-world water confidence and drowning-prevention skills.

But TriSwim is more than swimming. It is a social enterprise rooted in community wellbeing. Throughout the year we host Super Clubs, craft evenings, music-themed socials, yoga and breathwork sessions, as well as UK and international swimming and wellness escapes designed to nourish mind, body and spirit.

Whether you join us for a gentle dip, structured coaching, a wellbeing workshop or a once-in-a-lifetime retreat, TriSwim is a place to feel supported, seen and part of something meaningful.

Here, water is more than water.
It’s connection.
It’s confidence.
It’s community.

Welcome to TriSwim.
