The Science and Art of Open Water Swimming

The Science and Art of Open Water Swimming

The Science and Art of Open Water Swimming explores what it really takes to swim well and safely, in open water. Hosted by endurance swimming coach and sport scientist Grant Landers, the podcast brings together swimmer stories, coaching insights, and evidence-based science to unpack performance, preparation, and decision-making in unpredictable environments. Each episode features conversations with open water swimmers, triathletes, coaches, and researchers, covering topics such as training alongside work and family life, adapting to conditions, managing uncertainty, and learning from both success and setbacks. The podcast is informed by Grant’s work coaching endurance swimmers and triathletes, as well as his research at the University of Western Australia, but it’s intended for the broader open water swimming community. Whether you’re preparing for your first open water event or refining your performance at the endurance end of the sport, this is where swimmers, science, and the sea converge.
