Description

Susan Sherwin is one of the founders of IISA (International Ice Swimming Association) Aotearoa New Zealand and runs the annual NZ Ice Swimming Championships . An ice swim needs to be in water that's 5°C (41°F) or less, swum only in togs, goggles, a standard cap, and with optional earplugs.

Susan is an accomplished ice swimmer herself, having completed two 'extreme' ice miles (2km). She is also one of just a handful of people to have achieved NZ's Triple Crown: Lake Taupō in 2020, Raukawa Moana / Cook Strait in 2021, and Te Ara a Kiwa / Foveaux Strait in 2022 at the age of 61. She now has her eye on Australia's Triple Crown – within two weeks this year she completed the Rottnest Channel Swim (20km) in Western Australia and the Derwent River Big Swim (34km) in Tasmania.

In this episode Susan talks about how she returned to swimming in her 40s after having kids, gradually building from a few kilometres to ultramarathons. For her, it's about being in the water, enjoying people and nature, and saying yes to new opportunities.
