What did you to celebrate your 40th birthday? Well Jo Kane (aka my Mum) decided that it would be the year she would swim the Cook Strait. It's an amazing story, considering she first set her sights on the notorious piece of water at age 16. Jo talks about the endurance training and mental toughness she built up over many years, and how she was able to turn around and complete the swim just weeks after a failed attempt. And yes, there's a shark in this story.
