Inspires you to live bigger!

I’ve been busting for Lachie’s book to finally come out — and it did not disappoint! This book inspires you to live bigger, and if that’s not reason enough to pick it up, I don’t know what is. PS: I’ll be getting a paperback copy for my bookshelf too!!

Buy yourself a copy… and another!

I powered through this book — couldn’t put it down. Lachlan has shown true physical and mental grit, and great vulnerability in writing it. Inspirational, jaw-dropping, and a powerful message that anything is possible. I watched the doco too and was equal parts speechless and in awe. Loved it so much I’m buying a hard copy for the shelf. Highly motivational.

States of Mind — the #1 best-selling memoir by Lachlan Stuart.

The book

Fifty-eight marathons. One long becoming.

Not the highlight reel — the states of mind you move through when the achievement stops being the point.

“What am I really capable of?” That was the question Lachlan Stuart couldn’t escape. By 2024 he was coasting in the comfortable hum of Nashville — until, inspired by his wife’s relentless pursuit of her own dreams, he went looking for a mountain of his own: 58 marathons in 58 days, across every U.S. state and Australian territory, in the brutal heart of winter. But the real battle wasn’t the frozen trails or the injuries — it was the inner voice that called him a fraud. States of Mind is the raw story of what happens when you stop fighting the pain and start choosing who you become.

The story

Toowoomba to two continents.

“Every transformation begins the same way. Not with confidence or clarity or a sunrise, but with a moment you aren’t ready for, and a decision you make anyway.”

It began at rock bottom in Toowoomba, long before any finish line. States of Mind is the story of the person waiting on the other side of the pain — and everything it took to become him.

The cold. The breakdowns. The inner voice that kept calling him a fraud. And the people who carried him when his own legs wouldn’t. This isn’t a highlight reel; it’s what the road stripped away, and what was left once it did. Life isn’t a place you arrive at. It’s a state you keep building.
