Expand What You Believe Is Possible

Endurance Athlete and Performance Coach

Helping high performers train their body and mind for extraordinary performance and the best possible life.

"The best moments in our lives, are not the passive, receptive, relaxing times—although such experiences can also be enjoyable, if we have worked hard to attain them. The best moments usually occur when a person's body or mind is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile."

— Mihaly Csikszentmihalyi
About

Mason Newberry

I spent four years in corporate jobs that looked good on paper and never felt like mine. In that same window I went from a Thanksgiving 10K to 12 ultramarathons in three years — four 100-mile finishes, the Cocodona 250, and a few wins and course records along the way.

The races taught me that most limits are beliefs, and beliefs change when you give them evidence. In December 2025 I left my career to coach full-time.

My faith in Christ is the foundation of how I live and work. I love ultrarunning because it gives me a place to get fully absorbed in what I'm doing, test myself, and keep finding out that I'm capable of more than I assumed. Now I help men get clear on the life they actually want and start building it. I live in Austin, Texas with my fiancée, Kelly.
