Your daily nutrition matters, no matter how competitive or recreational you or your sport is. It shapes how you train, recover, adapt with age, and stay confident in your body over time.
I’m Dina Griffin, a Board Certified Sports Dietitian, Registered Dietitian Nutritionist, and endurance athlete. I work with active adults in the 40-75 age range and endurance athletes who want nutrition that supports performance, resilience, and long-term health, without extremes or gimmicks.
Many of my clients are consistent, motivated, and already doing a lot “right.” What they’re missing isn’t effort, it’s clarity. They want to know how to fuel their body, at this stage of life, for the training and goals they actually have.
My work focuses on:
Practical daily nutrition that supports training, recovery, and longevity with an emphasis on women’s health
Event fueling strategies that reduce guesswork and GI issues with an emphasis on running/ultrarunning, cycling, and triathlon
Navigating aging, changing physiology, or health conditions while staying active
Using metabolic and testing data to guide informed decisions and set a plan in motion for success
The process is collaborative, realistic, and grounded in real life. Nutrition should support your training and your life, not feel like a second job. And yes, we usually have some fun along the way.
