What can marathon swimmers teach us about staying safe in open water? Can we really adapt to cold water? And why are researchers increasingly interested in the connection between outdoor swimming, wellbeing and mental health?

In this episode, I sit down with A/Prof Heather Massey, an environmental physiologist at the University of Portsmouth and a leading researcher in cold-water immersion, swimmer safety and outdoor swimming. Heather is also an accomplished marathon swimmer, having completed a solo English Channel crossing, multiple Channel relays, and represented Great Britain at the World Ice Swimming Championships.

During our conversation, we explore Heather's journey into open-water swimming, what she learned from her English Channel crossing, and the unique physiological and psychological demands of marathon swimming. We discuss cold-water adaptation, hypothermia, SIPE, swimmer safety, and some of the misconceptions that continue to surround cold-water swimming.

We also discuss Heather's research into outdoor swimming and mental health, why scientists are increasingly interested in the potential benefits of outdoor swimming, and what questions remain unanswered.

Whether you're training for a channel swim, preparing for your first winter season, or simply curious about the science behind open-water swimming, this episode is packed with practical insights and thought-provoking discussion.

Heather will be visiting Western Australia next month as part of a UWA Institute of Advanced Studies Visiting Fellowship, where she will present public talks on long-distance swimming, outdoor swimming, and mental health. This conversation offers a wonderful introduction to Heather's work ahead of her visit.

In this episode of The Science & Art of Open Water Swimming, I sit down with Ceinwen Roberts; marathon swimmer, coach, event organiser and one of the most influential contributors to open-water swimming in Western Australia.

From her early days in the pool to becoming an Australian Hall of Fame marathon swimmer, Ceinwen reflects on a lifetime spent in and around the water. We explore her journey to 34 solo Rottnest Channel crossings, breaking the longstanding women's record, completing a Rottnest Triple Crossing, circumnavigating Rottnest Island, and setting a world record across the Bristol Channel.

But this conversation goes well beyond achievements. Ceinwen shares the lessons she's learned from decades of marathon swimming, the role the ocean has played throughout different stages of her life, and how some of her most meaningful experiences have come through helping others achieve goals they once thought were out of reach.

We also discuss the origins of Positive Swim Squad, the creation and growth of Port to Pub, the evolution of open-water swimming in WA, and her reflections on community, resilience, family, and what it means to spend a lifetime connected to the water.

Whether you're training for your first ocean swim, preparing for a channel crossing, or simply love stories from the open-water community, Ceinwen's warmth, humour and perspective make this a conversation not to be missed.

The Rottnest Channel Swim is one of Western Australia's most iconic sporting events, attracting thousands of swimmers, paddlers, skippers, volunteers and supporters each year. But behind every successful crossing is a huge effort to balance tradition, participation and swimmer safety.

In this episode, I speak with Will Rollo, President of the Rottnest Channel Swim Association, about his own journey in open water swimming and what it means to help steward one of the world's largest open water swimming events.

We discuss the origins and evolution of the Rottnest Channel Swim, the role of teams and solos in growing the sport, the contribution of paddlers, skippers and volunteers, and how the Association approaches risk management, safety and decision-making in an increasingly complex environment.

We also explore the role of research and innovation, including Swimming Induced Pulmonary Oedema (SIPE), route optimisation technology, weather-related challenges, out-of-event crossings, and the opportunities and responsibilities that come with guiding the event into the future.

Whether you're planning your first crossing, supporting a swimmer, or simply interested in the people behind major endurance events, this conversation offers a behind-the-scenes look at the stewardship of the Rottnest Channel Swim and the community that makes it possible.
