About Me
I’m Tia, a proud Australian born in Nambour, Queensland. At 24 I became the ‘Fittest Woman on Earth’ when I won the 2017 Crossfit® Games. I’ve since gone back and done it again.

But this book isn’t really about the trophies. It’s about everything that happened before them.

What I’ve Achieved
• 2025, 2024, 2022, 2021, 2020, 2019, 2018 & 2017 CrossFit® Games Champion
• 2018 CrossFit® Pacific Regionals Winner
• 2018 Gold Medalist representing Australia at the Commonwealth Games for weightlifting
• 2016 Rio Olympian representing Australia for weightlifting
• 2016, 2015 2nd CrossFit® Games

Why I Wrote This Book
“Ever since I was in primary school I loved to compete. I lived for sport, particularly running and would push myself to the limit to become better than yesterday. It may come as a surprise to you, but I always came second; I was always the underdog, that person who just fell short. But something in me never gave up, I just felt that fire in my belly get stronger and stronger, I wanted to do more, be more, achieve more.

The day I finally came first was something I had always dreamed of. At twenty-four years old, I was crowned the winner of the 2017 CrossFit games and officially became the Fittest Woman on Earth. When I heard my name called in front of thousands of cheering fans, I felt like I was invincible, I felt like I was on top of the world and like everything up until that point actually made sense.

With the support of my family, my partner Shane and coaches along the way, I was able to finally achieve my dream of being number one. This is my story of how I got to where I am today. I hope you enjoy it but more importantly I hope that it inspires you to dream big, work hard and never give up.

If you’ve ever felt like the underdog, like you keep coming close but not quite getting there, this book is for you. I wanted to share the whole climb, not just the moment on the top of the podium.”
