Croix Sather

Welcome to the Arena — where impossible is just the starting line.

I am 1 of 5 people to run through Death Valley desert solo self-contained unassisted crossing. 

146 miles.
120 degrees heat.
Pushing a cart that holds my food, water and supplies

In 2012 I broke the record by almost 5 hours
4 days later, I lost the record when another athlete broke it.

Now, age 55, I am going back to reclaim my world record. 
August 2026

I will be the oldest person to cross the desert. 

This isn't just a race; it’s a masterclass in Radical Resilience.
This channel is about the training at 8,500 feet, the mental battles, the business strategy behind extreme goals, and the unfiltered truth about what it takes to achieve something extraordinary.


I am ultra-endurance athlete, author and keynote speaker, sharing the blueprint to "impossible" goals and remarkable achievements.

Whether you're building a company, leading a team, or defining your next move—this is for the ones who refuse to settle.
