Liz Denyer's Epic Journey: Conquering the Cook Strait (2026)

Imagine diving into the ocean, knowing that beneath you lurks a world of sharks and stingers. For most, it's a terrifying thought, but for Liz Denyer, a Townsville woman, it was a challenge she eagerly embraced.

Liz recently conquered the Cook Strait, a 22-kilometer stretch of water separating New Zealand's North and South Islands, an achievement that puts her in an elite group of marathon swimmers.

"Every swim is a unique journey of self-discovery," she says, reflecting on her experience.

And what an experience it was! Liz braved the cold, 14-degree water and encountered a swarm of stingers, which, as she humorously puts it, "got me everywhere." Despite the discomfort, she persevered, completing the swim in an impressive eight hours and 20 minutes.

But here's where it gets controversial: Liz's swim was part of a larger challenge known as the Ocean Seven, which consists of seven open-water swims, each more daunting than the last. In 2023, Andy Donaldson from Perth set the record for the fastest Cook Strait crossing, finishing in just four hours and 33 minutes.

So, what drives these marathon swimmers? For Liz, it's about pushing her body to its limits and appreciating the beauty of her surroundings.

"I looked ahead, and there was this breathtaking sunrise. That's why I do marathon swimming," she says.

Her support team, including her former coach and loved ones, played a crucial role, providing food and encouragement every step of the way.

And this is the part most people miss: marathon swimming is a growing sport, especially among older adults. Christian Renford, president of Marathon Swimming Australia, explains that the low-impact nature of the sport makes it appealing to those over 35.

"It's not about the time, it's about the distance," Renford says.

So, are you ready to dive into the world of marathon swimming? Or do you think it's an extreme sport best left to the brave few? Let's discuss in the comments!
