Our Mission is to increase women’s participation and opportunity in trail running and hiking through inspiration, education and empowerment.
I’m Erin McCarthy—a gut health nutritionist, endurance trail runner, and certified running coach. I came to this work through my own healing journey, navigating digestive dysfunction, inflammation, and burnout while chasing big running goals. After years of being plant-based and struggling with energy, I learned how to nourish my body in a way that truly supported my lifestyle. That experience shaped my belief that there’s no one-size-fits-all solution—just your body’s unique story, and the right tools to help you listen.
I started running later in life and quickly became very passionate. I continued to increase my distance goals and ran Western States successfully in 2022.
"I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel."
I’m a Nutritional Therapy Practitioner and Master Restorative Wellness Practitioner, with a passion and extensive training in gastrointestinal healing arts. I also hold a certification from the United Endurance Sports Coaching Academy (UESCA) as a Running Coach. My work is deeply rooted in bio-individuality, whole food nutrition, and functional testing to get to the root of symptoms. I combine science-backed protocols with a compassionate, real-world approach to help you feel empowered in your body again.
I support active women—especially runners—who are dealing with bloating, fatigue, irregular digestion, and hormone imbalances. Services include 1:1 nutritional therapy, functional gut testing, personalized nutrition and lifestyle plans, and run coaching for those looking to improve endurance while staying healthy and strong. Whether you’re looking to heal your gut, better fuel your miles, or simply feel more like yourself, I’m here to guide you.
