Hi, I’m kate
I help high-performing women go from running on fumes to hitting big PRs on race day, using a data-driven framework that aligns with their physiology and their real life.
I’m a performance nutrition coach, Air Force veteran, and women’s hormone health specialist. I help high-performing women stop outpacing their capacity and start building the systems, strength, and fuel required to truly perform.
My clients track their macros, their mileage, and their ovulation…
But despite all that data, they still feel off. Fatigued, disconnected, or like their body isn’t keeping up with their goals.
Sound familiar?
I get it. Because I’ve lived it.
I know the pressure of trying to do it all while your body whispers, “not like this.”
That’s why my approach blends science, structure, and strategy to help you finally train smarter, fuel better, and perform like hell, without sacrificing your health.
With a Master’s in Psychology and over a decade of coaching experience, I specialize in helping women:
Reconnect with their body and cycles
Rebuild trust with their training
And get real, sustainable results without burning out
Whether you’re training for a marathon, trying to conceive, or just trying to stop white-knuckling your workouts, this is the space where your goals and your health finally work together.
No fluff. No fads. Just data-backed, mindset-rooted coaching that meets you where you are and pushes you toward what you’re actually capable of.

What 1:1 coaching with me actually looks like:
At its core, 1:1 coaching with me is about building a body and a system that can actually support the life and training you’re asking of it. I don’t just “give macros” or hand you a generic running plan.
I coach fueling, running, and strength together, in real time, so your training, recovery, hormones, stress, and lifestyle are all working in the same direction instead of competing with each other.
Inside my 1:1 coaching container, I personalize your macros and fueling strategy based on what you’re training for right now, whether that’s building muscle, preparing for a race, navigating pregnancy, returning to working out postpartum, or simply trying to feel like yourself again.
I write your running program with intention (volume, intensity, and pacing that match your capacity), and pair it with a strength training plan designed to support your running, not sabotage it. Every piece adjusts as your life adjusts: sleep, stress, travel, menstrual cycle, workload, and energy all inform how we progress.
What makes this different is that everything lives inside my custom framework called The Capacity Project. We’re not chasing short-term outcomes at the expense of burnout. We’re building resilience, both physically and neurologically, so you can train harder when it’s time, recover faster when it’s needed, and navigate seasons like pregnancy, postpartum, high-stress work phases, or heavy training blocks without falling apart. This is coaching for women who want to perform well and feel good doing it, now and long term.
