The Cole Classic is Australia’s largest ocean swim, covering about 9km from Sydney’s Dee Why beach to the iconic sands of Manly. In this, it’s 30th year, the Cole Classic has attracted thousands of swimmers from around the world who each commit to raising funds for local charities. But this year’s competitors won’t just be made up of seasoned athletes and competitive swimmers.

This year, 15 year old Jai will be taking on the challenge of the Cole Classic, but he does so with an agenda. As a sufferer of Friedreich’s Ataxia, a so far incurable disease of the central nervous system, he is raising funds for ongoing medical research. He knows he can’t do it alone – so he’s asking for others to lend him some muscle. You can support Jai’s swim here.
