Built for runners training for a half and full marathon — who are ready to stop guessing and start fueling with a plan.
THE PROBLEM
You have a training plan.
Nutrition still feels like guesswork.
You know your weekly mileage. You know your long run distance. You know your pace goals. But when it comes to food? You're piecing things together from Instagram posts, running friends, podcasts, and random Google searches — hoping it adds up to enough.
Meanwhile you're asking yourself...
Am I eating enough? Or, is this nighttime hunger a sign I'm eating too much?
Why am I so wiped out after long runs and spend the rest of the day recovering?
Why do I still 'hit the wall' even when I fuel well?
Why does my stomach rebel on long runs or sometimes just on race day?
Why do I find myself eating my kids' snacks or spoonfuls of peanut butter at 9pm and then feel guilty about it?
WHAT'S ACTUALLY GOING ON
Here's what most runners don't realize about their nutrition
Training for a half or full marathon increases your energy needs — sometimes dramatically. But hunger cues, habits, and "normal healthy eating"don't automatically adjust with your mileage.
So even runners who are genuinely trying — prioritizing protein, eating fruits & vegetables, limiting processed foods, doing everything they think they're supposed to do — often end up underfueled.
Not because they lack discipline.
Because nobody ever taught them how to eat like a runner.
THE SOLUTION
Introducing the Marathon Nutritionist Fueling System
Instead of piecing together general nutrition advice that may or may not work for your body, your schedule, and your training —you get a personalized, step-by-step fueling plan designed specifically for runners training for a half or full marathon.

REAL RESULTS
What happens when runners finally fuel properly
Jim — Boston Marathon
MARATHON RUNNER 20-MILE LONG RUN
A month before he emailed me, Jim finished a 20-mile long run dizzy and almost passed out. He was training hard and putting in the work — but not getting back what his effort deserved. One month later he ran the exact same route.

"The long run isn't train wrecking everything. What a difference it's made in my day and weekend."
— Jim, Boston Marathon
Robin — Quad City Marathon
BUSY MOM · 45 MILES PER WEEK
Robin came to me eating carefully, putting in the miles, and doing everything she thought she was supposed to do. She thought she had her nutrition figured out. She didn't — and she had no idea.
GI issues resolved completely
No more intense cravings or binge eating
Faster recovery, harder workouts
More energy for her kids and husband
"My mindset about food has completely changed. I now look at food as fuel — and I can give more of myself to my family."
— Robin, Quad City Marathon
