Meet Mason

The Coach Who's Actually Done It.

I'm Mason Wright (aka. Buff Runner). Sports Dietitian. Ultra Endurance Athlete. I was the 1st American & 3rd person in history to run 1,000 miles around a track, I ran 421 miles across the state of Utah, and have run countless other ultra marathons, marathons, & triathlons to prove nutrition is everything.

I weigh over 200 lbs. I am not the "traditional runner". But that's exactly the point and why I know how to build a fuel plan that holds up when everything gets hard.

Why It Works

The difference between hitting the wall and breaking through it? Knowing exactly what to eat, how much, & when.

Most athletes know how to train. But what about your nutrition? That gap between what you eat and what your body actually needs is where races are won and lost, where PRs happen or don't, where you either feel strong at mile 20 or you're just surviving it.

You don't need to guess anymore. You need a fueling strategy built specifically for your body, your race, and your goals. One that holds up when the pain cave begins.

★★★★★

"I'm not being dramatic when I say that working with Mason has completely changed my life. He takes the time to explain how my body absorbs different nutrients — and how to get the most out of my food choices. Before working with him I struggled to get to 2,000 calories in a day. Now I can easily get 3,500 in when prepping for a race. He has also helped me gain almost 20 pounds since we started. I love that he goes into detail about the 'why' so I can properly understand the reasoning. Absolutely love the dude!"

"Mason helped me dial in my nutrition for multiple races, helped me lose 80lbs this past year, and mentally helped me prepare for some of the toughest things I have ever done — like running across the state of Tennessee. I would not have been as confident without his guidance and coaching."

"I thought I had my nutrition figured out… turns out I was wrong. Since working with Mason, my recovery is faster and my energy has gone from night to day. I used to feel gassed after workouts — this past October I ran my first ultra marathon and felt stronger than ever. He makes nutrition simple and realistic, even with a 'too busy' schedule."

"Mason helped me understand how my disordered eating habits were holding me back athletically and how to dial in my nutrition to better support my body. With his guidance, I was able to conquer the Grand Canyon and now I'm looking forward to crushing my first ultra this spring."
