"Tim Walther has created a global community of extraordinary people actively engaged in living big and leading by example.”

Stu Mittleman, Ultra-Distance World Champion and Member of Ultrarunning Hall of Fame

Different from other adventure inspired literature, Tim dives deeper into his exploits through his ‘epiclogues’ where he bridges the gaps between the physical, emotional and spiritual elements of struggle and imparts tangible reflections, sage advice and neat conclusions. An inspiring read for anyone dreaming of adventure.

Ashley Futral Chapman: Freediver; 3 Time World Record Holder, 17 Time National Record Holder

Through edge-of-your-seat storytelling and thoughtful reflections, All In Adventure Stories provides compelling, insightful and empowering stories that will not only inspire you to live your dreams, but also give you a method to turn your dreams into reality.

In addition to adventure stories, the book details the seven steps of the “All In Adventure Method”, which draws from Walther’s hard-earned lessons to give readers a powerful and practical framework to successfully create and share your own adventures.

"Tim has created original and very challenging adventures, learned through his experiences, and shares hard earned wisdom with his readers.”

Lynne Cox, Legendary endurance swimmer, World Record Holder and Author of Swimming to Antarctica

Adventure isn’t just an activity that gets you an adrenaline rush. It’s a gateway into a more vibrant way of living – world travel, personal discovery, the application of peak-performance strategies, an opportunity to contribute, and a way to inspire others to reach their own highest potential.

Rest assured, you don’t have to be an extreme athlete to appreciate this book. Being afraid, making hard decisions, navigating chaos, stretching beyond your ability, and digging deep to manifest your next evolution are as relevant in business and family life as they are on wilderness expeditions. These lessons learned are valuable for anyone interested in achieving peak performance in any domain.

The goal of All In Adventures Stories is to ignite the passion inside each of us so we can live it and share it. 

But this is more than just a book – it’s a portal. We are creating a platform and a community for others to create, live, and share their own adventures. In the future, we’ll publish follow-up editions, authored by you and others like you. 

This book is just the beginning – a spark to light a fire of passion in the world.

The adventure of life is calling. It’s time to go ALL IN.

Who is this book for

Leaders and Entrepreneurs

The best leaders are familiar with the challenges of navigating chaos, handling difficult emotions, making hard decisions, and inspiring others to be and give their best. This is no easy task. Besides the rocket boost of inspiration you’ll get from these stories, you’ll also take away immediately applicable strategies and tools that can show you life from a whole new perspective and improve the way you lead.

Adventure Athletes

So you’re the kind of person whose vacations elicit “Are you insane?!” from most people. You know how to expand your limits and you love doing it. Welcome.

Let’s face it, big adventures, give us a lot. They connect us to something larger; they make us feel alive; they satisfy something deep within us. They also ask a lot from us - not just time, effort, focus, and resources, but they ask us to risk our lives. This inherent danger is part of what makes them so tantalizing. Besides fueling your motivation to continue your adventurous escapades, another purpose of All In Adventure Stories is to give you a tried and true method to plan and execute your adventures in a way that greatly reduces your risk of injury while simultaneously increasing your overall enjoyment of the experience.

Seekers of Adventure in
“Normal” Life

Yes, that’s right, you don’t have to climb dangerous mountains or travel deep into a foreign jungle to bring adventure into your life. There are plenty of “normal” life activities that we can enhance with the lessons learned from big wilderness adventures. How about the adventure of raising amazing children, becoming a stellar performer in work that you love, or cultivating a deeply satisfying intimate relationship? Sometimes we don’t have to leave the house to encounter some of life’s greatest adventures.

Peak Performance Enthusiasts

So, you like to be good at things - really good. For you, an upper limit is more of a suggestion than a boundary. “That’s impossible” isn’t in your vocabulary. All In Adventure Stories author, Tim Walther, is with you, and has been studying and applying peak performance strategies from the best trainers in the world for decades. If you want access to some of the most effective Peak Performance strategies and inspiration to implement them, you've come to the right place.

Armchair Adventurers

We get it. You might not up for a life of adventure, but you love reading about the stories of others pushing their limits. You get a thrill from living vicariously through them. Perhaps that inspiration and excitement fuels you in other areas of your life. All In Adventure Stories provides 17 edge-of-your-seat thrillers that are sure to entertain and inspire you.
