MEET YOUR SPORTS DIETITIAN

Grace Kelley, MS, RDN

Sports Dietitian for Endurance Athletes

I’m a Sports Dietitian and endurance athlete based in Chicago. I work with runners and other endurance athletes who are putting in the work but still feel flat, broken down, or stuck when it comes to performance. Most of the time, the problem isn’t training… it’s fueling.

QUALIFICATIONS AND EXPERIENCE

  • Registered Dietitian Nutritionist (RDN)
  • Master of Science in Nutrition from Case Western Reserve University
  • Master of Education in Exercise Science from Cleveland State University
  • Bachelor of Science in Psychology from University of Denver
  • Experience with collegiate, recreational, and elite-level athletes
  • Specialized focus on endurance sports nutrition, underfueling, and Relative Energy Deficiency in Sport (REDs)
  • Trained in fueling strategies for high-volume training and race-day execution

  • Endurance athlete with lived experience navigating underfueling and recovery

My work blends evidence-based sports nutrition with real-world strategies that fit the demands of serious endurance training.

HOW I GOT HERE

I know what it’s like to care deeply about your sport and feel the pressure to do everything right. 

As a swimmer-turned-triathlete in college, I trained hard, ate “clean”, and believed that lighter meant faster. That approach caught up with me. I dealt with persistent bone stress injuries, fatigue, and the physical and mental consequences of underfueling for many years.

What surprised me most was that eating more didn’t take away from my performance… it let me do what I loved better than ever before. Once my fueling matched my training, I could train consistently, recover better, and actually show up on race day. 

My experience as an endurance athlete has shaped my nutrition practice today.

MY APPROACH TO SPORTS NUTRITION

I take a performance-first approach to nutrition. That means fueling enough to support hard training, recovery, and long-term health instead of chasing restriction or arbitrary food rules. 

I don’t hand athletes a generic meal plan and send them on their way. Instead, we build a fueling strategy that works for your training volume, schedule, GI tolerance, and race goals. From long runs and workouts to race week and real life, the goal is confidence – not guesswork. 

I combine evidence-based sports nutrition with practical strategies that actually work for high-mileage, high-performing athletes. 

Because faster doesn’t come from eating less. It comes from fueling better.

WHO I WORK WITH

I work with runners, triathletes, cyclists, swimmers, and other endurance athletes – from recreational to elite – who want to train hard and race well without sacrificing health.

Many athletes I work with are:

  • Consistent in training but struggling with energy, recovery, or recurring injuries
  • Dealing with signs of  underfueling or REDs like loss of menstrual cycle 
  • Tired of bonking, GI issues, or fading late in races
  • Chasing a PR, BQ, or their strongest season yet

If you care about your sport and want a sustainable way to perform at your best, you’re in the right place.
