For The Athlete That Is Ready Go Beyond Macros, Calorie Counting And Plans That Aren’t Specifically Designed For Your Health AND Performance In The Past.   

Discover Strategies That Are Based On YOUR Unique Physiology and Take Your Performance To A Whole Different Level

Together We Build A Plan That’s Specifically For YOU Using SIMPLE Strategies In Hydration, Fueling, Nutrition and Lifestyle Habits That’s Focused On Your Health And Taking A Whole Body Approach.

If you’ve experienced missing your goal, PR, podium by JUST a few minutes or seconds and you know that something isn’t quite right with your nutrition and health markers, then you’re probably feeling pretty frustrated and need to get this “all figured out”.

Perhaps you’ve experienced the “bonk” or the low energy state, or maybe just watched your times get longer and longer as your qualification or goal time starts getting further and further away.

If this is you, then chances are you may have also experienced symptoms from not eating enough food day to day, increased soreness post workouts that doesn’t go away for multiple days, perhaps a pain or a niggle that just doesn’t seem to go away, or maybe even GI distress or symptoms on race day.   

Maybe you’ve walked into your doctor’s office listing a few symptoms like: “fatigue that just isn’t normal”, or “I think my hormones are off”, or “something isn’t right with my gut” and you were written off as “it’s because you workout a lot”.

And if you’ve experienced any number of these scenarios, then you also may have fallen into the “trap” of thinking that to get more results you have to keep training harder, sacrifice sleep, and maybe even switch coaches, get new equipment and just overall DO MORE.

Perhaps you’ve also tried ALL the different fueling products or are thinking you need to be super strict with your nutrition (OR the opposite and eat even more foods that are actually causing inflammation), but the truth is… The real culprit is this approach doesn’t take into account who YOU are and your specific needs – your genetics, your physiology, your lifestyle and your training.

In order for you to be successful and perform symptom free, you need the support and answers to how to put together nutrition, fueling, hydration and health strategies that are based on your unique physiology – not what a coach or friend or someone else “thinks you need”.

What will happen if you continue to “wing it on race day”?

Have You experienced…


GI distress on course?


Bonking or cramping?


DNF’s due to fueling or hydration issues?


Low energy and pace drops throughout the event, especially towards the end?


Trying new foods/gels/fuels on race day or race weekend?


Spent time in the bathroom at each aid station?


Menstruating Women: have you noticed “flat” low energy workouts right before your periods?


Post Menopause Women: have you noticed a general decrease in power and speed after menopause?

Athletes tend to have strategies for their race pace and times, but often struggle with their nutrition strategies and if that’s you, this course is going to help you be confident in your nutrition so that you can focus on your training and performance.


If you’ve spent all year training and if you have your race strategy all locked in then in this course we are going to make sure your nutrition/fueling and hydration strategies are on point specifically for you.

The Fueling Performance Group Coaching Isn’t a “Nutrition” Course Like All the Others You may have taken

It’s a 6 month deep dive into your habits,

routines, health markers and more that will change you…

From overtrained, under-fueled to a

Confident and Powerful Athlete.

You’ll discover how to test and choose fuel, hydration, nutrition strategies that work with your physiology and how to tune out all the other noise.

You’ll get options for which labs would be the most helpful, when to supplement, and what supplements might be a good fit for you (no more guessing and “trying” things that you aren’t sure are working).

You’re put on a path to get results – instead of listening to more podcasts and trying to apply strategies that you hear from friends and pros that aren’t designed for you.

It turns everything you think you know about health, nutrition, hydration and fueling on its head.

Dr K

Dr K is an endurance athlete. Just like you. She also combines sports nutrition and fueling with a systems based functional medicine approach for athletes. She earned her Ironman title under extreme conditions at Ironman Coeur D’Alene, Idaho in 2021. The day set record temperatures with a high of 108 degrees, and highs of 130 degrees coming up from the pavement on the 112 mile cycling course.

She overcame two rounds of heat exhaustion and finished the race BECAUSE she made the right decisions for both fueling and hydration. It was because of her knowledge of exercise physiology and nutrition that she was not one of the 30% who did not finish the race that day.

She has helped herself through successful races and also helped many athletes overcome cramping, symptoms associated with under-fueling, GI distress and helped them fuel for performance.

… Which of these results would you like the most?

“I was still full of running even at the last hour of the race”


This is something which hasn’t really happened before, especially after having races earlier this year where I ran out of “energy” to keep going. This new fueling schedule has given me the confidence now to go and attack these races a little more. Thank you for working out the issues. – Mark Livesey Train Xhale & The Brick Session Podcast

“i hit a pr and with no gut issues”


Not having gut issues is a weird thing to go through in a race waiting for the other shoe to drop. I felt good afterwards, too and it’s an amazing feeling. Thank you for helping me work out the gut symptoms for my running and stand up paddle board races. – Christy SUP athlete and runner

What is fueling performance

group coaching?


1:1 session with Dr K

Start off with your own session with Dr K. We will cover your goals, training load, lifestyle and “stress” load, and other health related factors. We also discuss your current strategies and habits – what you’ve tried, what didn’t work, what your current frustrations or confusions are. We will also make sure to be specific about physiology and address where things are different if you’re a female or male athlete.


Get a Plan

Dr K will give you a strategy to start with and over the course of the next 6 months we’ll work on testing it and dialing it in. This includes pre-during- and post training nutrition/fueling as well as a strategy for race day as well.


Learn with the Group!

All follow up sessions will be with the group. Each month we’ll have 2 group sessions for training and classes on hydration, fueling, nutrition and recovery. There will also be time included for questions and making any adjustments to your plan based on your results from training the previous few weeks.



Get encouragement and learn from others in your cohort in your own private community space.

“I qualified for the chicago marathon at my last event – postpartum!”


I started working with Dr K because I am training for marathons postpartum and I wanted to make sure that my nutrition, health and fueling is all on point for my best performance.

– Bethany, Marathoner

“I thought my symptoms were due to ‘old age’, genetics, or perimenopause – turns out it was something really simple – a nutrient deficiency”


For a long time, my legs have felt terrible. So uncomfortable that I wasn’t sleeping well. Getting up from the couch was a strain and difficult for anyone nearby to witness. I continued to bike, run, and generally stay physically active, but great workouts were rare. Rest, stretching, and massage had little to no impact. The type of workout did not change the level of discomfort. Dr Kirstin helped me figure out it was a magnesium deficiency and after just 1 epsom salt bath I immediately felt relief. I now have a strategy to make sure I keep my magnesium levels in check.

I’ve helped weekend warriors, fitness enthusiasts,
amateur athletes and pro-elite, athletes conquer
hurdles with their health, nutrition, fueling and
hydration strategy and now it’s your turn!

My 1:1 clients pay me anywhere from $500 to $30,000 to work with me in a close setting.

Over the past few years, I’ve seen so many athletes struggle with their nutrition – from fueling and hydration mishaps to energy deficiencies leading to hormone imbalances, pain during training, GI distress, micronutrient deficiencies and so many more that have caused them to fall just short of a podium spot, a PR, or caused them to miss a race or not finish due to symptoms. This often turns into several races being affected and years of races “feeling like if you got this under wraps you’d be competing at an entirely different level”.

Which means if you never get this figured out, you’ll spend race after race trying new things and getting further away from your goal.

It’s for that reason that I want to make sure this training gets out to as many people as possible so that you can go out and race symptom free.


So tell me… are you in?

It’s EXACTLY what I teach and work with my 1:1 elite athletes at $30,000/year, but for a fraction of the cost for you.

And when you consider all that against the investment and what it will do for you and not just your

future in sports, but also you’re health, then it’s an easy choice.

Fuel products like gels don't cause any symptoms for me, why should i change what's working?

Different fuel sources use different carbohydrate/sugar sources. And some of those interact with the GI tract in a way that brings water into the gut causing faster dehydration. You may not get symptoms but it’s absolutely affecting your performance. 

It’s about knowing specifically what you need and what works with your physiology.

I've tried nutrition and coaching courses before, what makes this any different?

That’s actually a good thing! You’ll know exactly how to apply the particularsections of information that specifically works for you.

This course is not a one-size -fits all approach. It’s not about what your coach “thinks” is a good idea or what has worked for “other” athletes. This is about getting specific about what fits best for you – either by testing through training or ordering specific labs when and if you’re ready.

I'm not a high level athlete, is this course a good fit?

It’s not a matter of what level you’re at – we’re all athletes here if we are working towards a goal.

This course is about having the courage to commit, the courage to recover, and commiting to the coaching and applying the principles and strategies in this course.
