- Congratulations to Gráinne on her Oceans Seven!!!!
Gráinne Moss is an ultramarathon swimmer from Wellington, New Zealand who recently completed the Oceans Seven, a series of gruelling swims around the globe. It's been a 39-year odyssey for Gráinne, who swam the English Channel in 1987 at just 17 years old and completed her seventh swim in June this year at the age of 56. Gráinne swims under her Irish passport and is the first Irish woman (and 45th person) to complete all seven swims!
In this episode Gráinne (pronounced Gron-ya) shares stories from all seven swims, including swimming across the choppy English Channel as a teen in the 1980s; a "very, very large" shark encounter in the Cook Strait; battling 12-degree water and lion's mane jellies in the North Channel; the 42km 'Channel of Bones' in Hawai'i; and the thrill of completing the Oceans Seven in her mid-50s. We also talk about the swims that took more than one attempt and how they were learning opportunities that led to future rewards, and the ongoing support of her friends, family, and the wider swim community.

Thanks for listening! :-) - The Scarborough Dippers began with a bet between four friends in a coffee shop on a winter's day: who would take the plunge into the cold sea? Ten years later, the group now has dozens of year-round dippers who meet at 7am at Scarborough Beach in Christchurch.
The group also runs Wet July, an annual campaign to raise funds for local organisations including kindys, lifesaving clubs, and conservation groups. Members pledge to get in the sea every day of the month and the dippers often raise over $10,000. They also host a mid-winter community swim and a quiz night. Their bank details are Scarborough Dippers 01-0811-0814833-00 if you want to chip in!
Founding member Sandra Taylor came on the podcast to talk about how the group got started, their annual fundraising, the importance of a ‘Bucket of Joy’, and the support and connections that have formed from the fun and buzz of ocean dipping. As Sandra explains: “There’s no rules, no cost, no expectations, just a kind and lovely group of people that have all gathered around a love of dipping.”
Visit the Scarborough Dippers public page on Facebook to follow along (new dippers and visitors are welcome – there are daily dippers and their biggest turnout tends to be on Fridays).

Thanks for listening! :-) Squad coach and gym owner Timon Wilkinson on making lessons fun for kids and adults
15/07/2026 | 58 mins.Timon Wilkinson is the co-owner of Bonobos gym for kids and adults in Wellington and runs weekly Bonobos Swim Squads at Freyberg, WRAC, Te Ngaengae, and Te Huia Pools.
Timon was a competitive swimmer from nine to 15 and started coaching kids while he was at university. He worked at the old TSW Pool until it closed in 2017, and then for Capital Swim Club. In 2017 he co-founded the fun and friendly Bonobos gym in Lyall Bay for kids and adults (including Strength, Mobility, and Balance classes – great cross-training for swimmers!).
Timon talks about leaving kids' competitive swim coaching, opening the gym, and his many years of running adult swim squads. We discuss the joys and challenges of running squads, his top swimming tips, teaching different ages, personalities, and abilities, and how creating a friendly space helps people to learn and have fun so they want to keep coming back.

Thanks for listening! :-)- James Bell is a Professor of Marine Biology at Victoria University of Wellington – Te Herenga Waka, and a huge fan of sea sponges. Check out his colourful underwater photos and videos on his Instagram page, @sponge_ecology, where he has over 40,000 followers.
James has scuba dived around the world researching this ancient, vibrant, intriguing, but sometimes overlooked marine species. (We both agree that charismatic megafauna – e.g. dolphins, whales, sharks – often get a disproportionate amount of attention.)
In this episode we talk about the characteristics and role of sea sponges, where you can find them, and how they're responding to marine heatwaves and increased levels of sedimentation (e.g. Wellington's current wastewater treatment plant disaster).
James also talks about life as a marine biologist: diving in some of the world's coolest places, teaching the next generation of marine scientists, and sharing information to help people better understand and advocate for our underwater world.
Glossary:
Nudibranch: soft-bodied marine gastropods (sea slugs)
Bioactive: something that has a biological effect on living organisms
Spicules: needle-like elements produced by sponges to provide structural support and protection against predators
Glass sponges: sponges with skeletons made out of spicules (see above)
