Mariko Collins: Waves, Curiosity and Adapting in Open Water

In this episode, Grant speaks with engineer and open‑water swimmer Mariko Collins about how swimmers move in waves, and what those forces feel like in the body. Drawing on her research and her recent first solo Rottnest Channel crossing, Mariko reflects on adaptation, curiosity, and the psychological challenges that emerge when things start to unravel late in a long swim. This interview was recorded on Whadjuk Noongar Boodjar. I acknowledge the Noongar people as the Traditional Custodians of this land and pay my respects to Elders past and present
