Anthony Blazevich is a Professor of Biomechanics in the School of Medical and Health Sciences at Edith Cowan University. He is also the head of the Centre for Exercise and Sports Science Research, so is a fabulous person to talk to about biomechanics, body types and how our physiology affects our ability to move through water. Listen in to hear how you could tweak your stroke for quicker times, and why we still may see many more world records in the pool (and ocean). He has also conducted extremely interesting research on the benefits (or not) of stretching.

Rebecca Olive is an ocean swimmer whose academic research explores the role of sport and leisure in human and environmental health. In particular, her work explores the practices and cultures of ocean swimming and surfing to understand how human and environmental well-being interact, as well as our relationships to all things blue-space, such as sharks, animals, plastics, pollution and health. Her Moving Oceans website examines how participation in ocean sports shapes our behaviours towards taking care of the oceans. She has also published some fantastic reads in The Conversation - we talk about these two in the podcast: When we swim in the ocean, we enter another animal’s home. Here’s how to keep us all safe. Olympic swimming in the Seine highlights efforts to clean up city rivers worldwide.

Michelle O’Shea is a Senior Lecturer at Western Sydney University whose research interests dive into the areas of sport, culture and society, particularly with regard to swimming. She has looked into issues such as why swimming lessons for kids are important, as well as the role of the swimming pool in society. Her research particularly examines issues relevant to gender and diversity, and how the pool and the beach, despite the great Australian egalitarian myth, can be quite exclusionary places.

Rolf Hut is a hydrological scientist from Delft University of Technology. Or perhaps he's better described as MacGyver scientist, attacking problems from different and interesting angles. One such problem was the infamous 1962 escape from Alcatraz, in which inmates Clarence Anglin, John Anglin, and Frank Morris escaped from Alcatraz Federal Penitentiary, by tucking papier-mâché versions of their heads into their beds, escaping their cells through the ventilation ducts, climbing through an unused utility corridor, across roofs and over fences, before leaving the island on an improvised inflatable raft made of rain jackets. Rolf helped build perhaps the most sophisticated model of the currents in the bay area on the night of escape to look at the question of whether the inmates could possibly have survived the journey, and then tested the research in his own Mythbusters-esque escape from Alcatraz.

Andy Donaldson is a world-recorder holding open-water swimmer. In 2023, he is attempting to swim the Oceans Seven in one year, and is making a pretty good fist of it, having already swum the English Channel (in a British record time), the North Channel (only 4 minutes off the record), the Cook Strait (in world record time) and the Molokai Channel in Hawaii. At the time of recording, he was setting off to swim the Strait of Gibraltar - and by time I published, he had broken the British record. He is raising money for Black Dog Institute Songs in this episode - all licensed under a Creative Commons License: Andy - MisfitMediocrity Donald trumpet vs delirium (silence) - David (G.RaFF) parton Son Lux - Lost It To Trying (Umpire Remix) - Umpire Sapphire - Tobu Photo from Andy on instagram

Pedro Ordenes is an Alcatraz legend, having swum the famous route over 1000 times!! Pedro runs Water World Swim that organizes many swims in San Francisco Bay, California and across the world. I was lucky enough to swim Alcatraz with Water World Swim recently in April 2023. Pedro is an exceptionally accomplished open water swimmer, perhaps the highlight being swimming the Strait of Magellan in South America, in 3.5°C with 60 km/hr winds and 3-5 feet swells against 12-14 knot currents! He has also swum a double crossing of the Beagle Channel between Chile and Argentina. Pedro is now also a very well respected open-water coach.

Lynne Cox is arguably the most accomplished ocean swimmer of all time. She set the record for the English Channel in 1972, was the first woman to swim the Cook Strait in New Zealand in 1975, famously swam between the US and the USSR in 1987 across the Bering Strait in bone-chilling 3 degree waters, and then even colder in Antarctica and Greenland. She has a list of achievements too long to list here. Lynne is also an author, and has a new book called Tales of Al - The Water Rescue Dog, detailing her experiences with Italy's elite, highly specialized corps of water rescue dogs who jump from helicopters and save lives.

Professor Peter Ralph is Executive Director of the Climate Change Cluster in the Faculty of Science at UTS, and is partnering with Australian surf brand Piping Hot to develop textiles made from seaweed for surfwear. Nature-derived alternatives for the fashion industry have the potential to revolutionise products and vastly reduce their impact on the oceans.

Sharks are an ever present thought for ocean swimmers, and they are one of the topics in today's episode, which was recorded a few weeks before the incident. My sincerest condolences are with Simon's family and friends.  

Lauren Tischendorf is the first woman to swim solo around Lord Howe Island - 32.2 km of sharks, currents, 25 knot winds and 2.5 metre swell, finishing in 13 hours 50 minutes and 26 seconds. She has also filmed a documentary of the swim, I just went for a swim, highlighting the spectacular ocean as well as the importance of the empowerment of girls and women. You can watch this film throughout Australia very soon in the Women's Adventure Film Festival.

Brendan Cullen is training to swim the English channel, but what makes his journey exceptional is that he is a sheep farmer from Kars Station, east of Broken Hill in NSW, and is about 350 km from the nearest coastline. Four mornings a week, Brendan swims in the murky waters of Lake Pamamaroo and Lake Copi Hollow in the Menindee Lakes, where he can't typically see more than 20 centimetres in front of his face (video). And there's not a lot of open water in the desert!  Brendan already has some major swimming achievements under his belt, such as swimming for 8 hours non-stop, and he an ambassador for lifeline, raising awareness and money for mental health.

Peter Hancock has now swum well over 1000 consecutive days, most days in Dumaresq Dam in Armidale, central NSW. Often the temperature is down near freezing. But this is not the first time Pete has conquered an incredible swimming challenge. In 2014, he swam in 333 different locations in the one year, including in the 1.6 degree Fox Glacier River in New Zealand. As a freshwater ecologist, it's not just the swimming that Pete likes - there are plenty of things to look at! He has discovered new species of fresh water crustaceans and beetles,  and documents much of it on Instagram. Pete also recently completed an indoor Iron Man, raising money for Headspace. So he knows how to run and cycle as well! You can see his adventures on strava.
