Lift Heavy. Run Far.

Sports nutrition coaching for endurance and outdoor athletes who train hard and chase big adventures

Personalized nutrition built around your training and your life.

You're not a casual gym-goer and you're not a professional athlete. You're somewhere in the middle crossing finish lines, chasing after your own PRs, and saying “yes” to adventures. 

Your nutrition should work as hard as you do, supporting the miles, the lifts, the summits, and the workdays, the stress, the sleep, and everything in between.

WHERE FUNCTIONING HUMAN MEETS FUNCTIONING ATHLETE

You're a gym rat. A runner. A mountain goat who does a little bit of everything. 

You train because it's part of who you are.

And your nutrition? Fine-ish. At least that's what you tell yourself.

Some days you feel great.

Others you're dragging through a workout that should've been easy, your gut is doing something weird in the afternoon, and your recovery is always lagging just enough for you to notice.

There is a version of you where:

You have consistent energy all week long, not just every few days.

Your sleep and recovery actually keep pace with your training demands.

Your gut stops being something you think twice about before a long run or a busy workday.

You know exactly how to fuel a marathon build or a 10-hour day in the mountains and still have something left when you get home.

That’s what we build together.

HI, I'M CALLIE.

I'm a board-certified Sports Dietitian with advanced training in Integrative and Functional Nutrition. I've spent my career working with some of the most demanding athletes on the planet, from US Special Operations Forces to Division I college athletics to endurance runners and mountain athletes who do hard things just for fun.

Having me in your corner means working with someone who blends the current science with real-world performance. It's not just about what's on your plate, but also your training load, sleep, stress, hormones, and how to build a fueling strategy that actually holds up in real life.

Oh, and like you, I live this lifestyle too. Thirteen half marathons in, serious miles on mountain trails, and I know firsthand what it feels like to train hard, eat well, and still feel like something's off.

I built Fueling Upward because athletes like you deserve more than textbook advice or a meal plan spat out by an AI chat bot. No cookie-cutter plans or one-size-fits-all advice found here. Just personalized, performance fueling strategies built around your body, your sport, and your everyday life.

    E.W. - Marathon Runner

  • "Thank you so much, Callie - the marathon was a success! I ended up finishing in 5:30:01 which surprised me because of the 1880' elevation gain! I did exactly what you recommended, and I did not feel the fatigue I usually feel toward the end of the run. Thank you so much!!!"

    K.L. - Trail Runner

  • "My performance during the ultra marathon was great, I can't believe I ran for 8 hours straight and didn't bonk! My diet has drastically changed for the better due to this intensive program. I am glad I know now how to adjust for small mile weeks vs. high mile weeks."

    D.T. - Endurance Athlete & Ultra-Runner
