Five-and-a-half years ago Lavington school principal Matt Kean received a diagnosis he wasn't expecting, ABC News reports.
He was diagnosed with stage three melanoma, which later was moved to stage four.
"As an educator, I didn't know enough, I didn't know enough as a parent and that's probably why I'm in the trouble I got myself into," Mr Kean said.
Mr Kean said he was lucky enough to undertake a two-year immunotherapy trial.
"I've had two years of that therapy and then two-and-a-half years of clear where every six-monthly scan has indicated no growth in the cancer."
Now Mr Kean is undertaking the Riverina Melanoma Ride across regional New South Wales and Victoria to raise awareness about the risk of melanoma and educate adults and children about how to prevent it.
"It's a little daunting," he said.
"The training is there; I'm hoping I've done enough, and I'll soon work out in the next couple of days."
Eight riders will travel 1,000 kilometres over eight days with others joining at different points along the way.
The ride kicked off from Lavington today and will take participants through Wagga Wagga, Leeton, West Wyalong, Lake Cargelligo, Griffith, Jerilderie, and Yarrawonga.
Mr Kean said 98 per cent of melanoma was due to the sun and he hoped his talks at primary and secondary schools would encourage students and their parents to think more about being safe in the sun.
