When Zac Pettit lost his best mate Zane to osteosarcoma, his life was forever changed. Being by his mate's side as he bravely battled cancer required Zac to navigate a broad range of practical, psychological, emotional and personal challenges that, at the time, were incomprehensible and somewhat terrifying for the (then) teenager. These days, Zac is running ultra-marathons, working as a sparky and doing his best to educate and inform the public about osteosarcoma, along with supporting people emotionally, practically and financially who are on their own cancer journey. He does this through the not-for-profit he created called T2KO. Good dude, good chat. Enjoy.
