Hello! I'm Brooke Bjorge - Mom, Registered Dietitian & Founder of Grit Sports Nutrition. I am a Registered Dietitian and Sports Nutrition Specialist!

I design custom fueling plans for endurance athletes to optimize their energy, body composition, and race-day performance. I have a BS & MS in Nutrition, and have been coaching athletes for over 8 years. I offer customized nutrition coaching & sweat testing for endurance athletes like swimmers, cyclists, runners, triathletes, skiers, climbers as well as individual and team sport athletes. Specific offerings include: diet assessment, specialized meal plan guidelines that stabilize blood sugar and encourage the body to burn fat, training/racing fuel plans and sweat sodium concentration testing.

How ChatGPT and I are different 😂 No matter how advanced we get with tech, never underestimate the value of HUMAN support.

1) you’re not drinking enough fluid
2) you’re drinking too much fluid
3) electrolyte imbalance (ahem, sodium 🧂)
4) your fuel timing, amount, type is off
5) you have nutrient deficiencies

GI issues during endurance sports are super common (and frustrating!). This list covers some of the common culprits. If you need help uncovering yours- reach out. I can help you fix it 💪🏻

Still pinching myself almost 4 years later that these Montana mountains are my playground 🥰 .conklin_

Can we please stop accepting stomach issues as the norm in endurance sports?!

Running 🏃‍♀️ • Triathlon 🚴‍♂️ • Ultras 🏔️ — you name it.

I’m SO tired of athletes resigning themselves to feeling like 💩 for days after a big effort.

When did it become “normal” to suffer through stomach pain, nausea, or cramping... and then just accept it as part of the sport?! 😩

It’s NOT about “just getting through” your race or adventure. It’s about fixing your fuel + hydration so you can actually perform at the level you’re capable of. ⚡️

👉 That’s exactly what I’m covering in my free live webinar:

I truly believe that if athletes had higher expectations for their fueling plans, we’d see WAY fewer stomach issues, cramps, and “post-race hangovers.”

It’s time to raise the bar 💪🏻

TBH, slamming down a bunch of protein first thing in the morning is tough for some (yours truly included 🙋🏼‍♀️). But it’s sooo important to establish blood sugar control and set the tone for the rest of the day. If you start the day with just carbs/sugar, guess what you’ll continue to crave?!

This pictured meal had 26 grams of protein 💪🏻 Whether it’s animal or plant-based protein, find some morning options that work well for you and experience better satiety, consistent energy levels and muscle building that supports the day’s activities 👏🏻

You might just see chips… but I see progress 💪🏻

The “Simply” line from Frito Lay dropped the artificial flavors and colors, and some varieties even switched to better oils. 🙌

Little changes like this show that when we ask for better food, companies actually listen. And that’s pretty exciting!

Post-race comments from Marah’s Mom, :

“She felt great!!! You were the lifesaver. The race was much more difficult than they had anticipated. Single track almost the entire way and technical sections sprinkled throughout. Her fueling was on point and her stomach felt good for once!

2016. I first started sweat testing Arizona endurance athletes nearly a decade ago when no one even knew what the heck a sweat test was 😝 was one of my very first guinea pigs- thank you Linds for trusting me!!

Fast forward nearly a DECADE and this test remains the gold standard for sweat composition testing (how salty your sweat is) and the Precision Hydration brand / products have exploded in popularity. You see, having a perfectly dialed in hydration plan is a true game changer for runners, ultra runners, cyclists, swimmers, triathletes, etc. The hundreds of success stories I’ve heard over the years would bring you to tears. Being able to offer this service to my local endurance communities has been one of my greatest priorities and joys.

Don’t worry! I’m not out of the sweat testing game but I will be housing my machine in Bozeman 100% of the time going forward. A huge thank you to and for learning the protocol and running my Arizona testing the last few years. This is bittersweet for me. BUT- is up and running in North Scottsdale and they are ready to take the reins. Reach out to Carson to book your test! 💦

And in the meantime, my remote fuel and hydration planning services will continue on as always. Reach out to me for info or visit www.gritsportsnutrition.com 🫶🏻 Thank you for 10 years.

Because I saw lots of triathletes in this position, doubled over and holding their cramping muscles. As we sweat, we lose sodium. And if lost in large enough quantities, muscle contraction is impeded and cramping begins. This is an avoidable condition- by knowing how much sodium you are losing. I offer the gold standard test for this, the Sweat Sodium Concentration Test. If you are in Arizona, my machine is currently down there with . for a few weeks. And if you’re in the Northwest, reach out to me for late summer scheduling in Bozeman. Cramps are preventable - don’t let them ruin any more of your endurance activities 💪🏻

One of my pet peeves as a sports dietitian:

I am soooo over stomach issues being accepted as the norm when it comes to endurance sports like running, ultra running, triathlon and cycling.

I am sooo tired of athletes resigning to feel like garbage for days after their events after a big effort.

It’s not about “just getting through” the event, race, or adventure.

It’s about FIXING the fuel and hydration issues so that you can excel to the level which you are capable of.

And that is what I am going to focus on in new my webinar. .

You can register here (it’s free) >>> https://pages.gritsportsnutrition.net/livetraining.

I firmly believe that if athletes had higher expectations out of their fuel plans, we would see so much less of the accepted issues like stomach issues and muscle cramping.

If you are with me on this, give me a 🙌 in the comments 🙂

My new webinar is live THIS FRIDAY! 3 Ways to Dodge Fueling Fails & Crush Your Endurance Sport.

If you’re feeling like a failure because you HAVEN’T yet figured out how to get rid of fueling-related challenges while endurance racing….

If you’ve been thinking you SHOULD be able to figure this out on your own…

Or thinking that “other people” have it more together than you and that asking for help means you are somehow less smart, capable, disciplined, or resilient...

Let me ask you this: If you don’t know how to fix your car, do you take it to a mechanic? Or if you don’t understand a legal matter, do hire a lawyer?

Sooo how is this any different?

I help my clients who have fueling-related challenges like GI issues, muscle cramping, inconsistent energy levels, etc. and I’d like to help you too!

My brand new web class is ready and you can register for free here >>> https://pages.gritsportsnutrition.net/livetraining.

All of the details, including the date/time, are on the registration page. Even if you can’t make it live, still register so I can send you the replay.
