Expert Sports & Triatlete Dietitians Providing Nutrition Coaching with REAL Results

Sam B. Testimonial

“I’ve been working with FlyNutrition for over a year now to dial in my nutrition during training and racing. The weekly meal plans ensure I am getting the right fuel to my body for my workouts whilst also being delicious and varied! FlyNutrition also helped me with a race fueling plan that helped me nail a recent 70.3 PR. I couldn’t have had the success in racing over the past year that I’ve had without FlyNutrition and I’m stoked to keep working together!”

Joanne E. Testimonial

“I’ve learned and grown a lot in the past half year. ‘Fuel for performance’ not only became a mantra but also served as a frame for me to understand how meal prep and tracking caloric balance are critical to performing my best. FlyNutrition helped and guided me through all this. Kylee has great expertise, and is also a wonderful person to talk to! It’s still a long path to go, but Kylee gave me the tools to keep going.”

Trish H. Testimonial

“I just wanted to thank FlyNutrition (times infinity) for all your time, energy, and expertise this last year! I had the physically strongest training block of my life. Mentally strongest as well. I know that was in no small part due to all your amazing nutrition and fueling guidance. My body is getting the right amount of food and nutrition to fuel itself and I’m clearly seeing what I can do when that is the case. You are so incredible and have made the biggest difference in my life.”
