If you’re going into HYROX just hoping your nutrition works… you’re already behind.

Most people don’t struggle because of fitness—
they struggle because they didn’t fuel properly.

Not enough carbs.
Wrong timing.
Trying new foods race week.

And it shows up exactly when it matters most.

This is exactly how to fuel for HYROX—without guessing, overthinking, or sabotaging your race before it even starts.

Simple. Structured. Proven.

Carbs aren’t the problem.
They’re the reason you can actually perform.

If you’re running, training, and still feeling flat, fatigued, or stuck… it’s probably not your workouts—it’s your fueling.

Runners don’t need less food.
They need the right fuel, at the right time.

This is how you stop hitting the wall, start recovering faster, and actually train at the level you’re capable of.

Because carbs aren’t optional for runners—they’re the foundation of performance.

Creatine: What You Should Know

Creatine is one of the most researched and effective sports supplements available. It’s naturally found in our muscles and helps regenerate ATP (cellular energy) so your body can produce more power during high-intensity activity.

Benefits of creatine may include:
• Increased strength and power
• Improved high-intensity performance
• Greater muscle gain over time
• Enhanced recovery
• Potential cognitive benefits

Who may benefit?
Athletes, lifters, runners, and anyone looking to improve performance, recovery, or muscle mass.

How to take it:
• 3–5 g of creatine monohydrate daily
• No loading phase required
• Take consistently, even on rest days
• Pairing it with a meal (especially carbs) may help absorption

Creatine is considered safe and evidence-based, though some people may notice a small temporary increase in body weight due to water stored in the muscle.

Under-Fueled → Fueled (Breakfast Edition)

A lot of people start their day under-fueled, especially when they’re training regularly.

Breakfast isn’t just about eating something quick—it’s about building a meal that actually supports energy, recovery, and performance.

A well-balanced breakfast should ideally include:
✔️ Carbohydrates for energy
✔️ Protein for muscle repair and recovery
✔️ Healthy fats for satiety and hormone support
✔️ Color (fruits or veggies) for micronutrients

Carbs get a bad reputation… but for athletes they’re fuel.

Whether you’re training for HYROX, running long miles, lifting heavy, or doing hybrid workouts — carbohydrates are your body’s primary energy source.

When glycogen stores are full, you can:
✔️ Train harder
✔️ Recover faster
✔️ Maintain endurance
✔️ Support performance

And contrary to what social media often says… carbs don’t have to come from only “perfect” foods. Sometimes the most practical options are simple, easy-to-digest carbs that help you hit your fueling needs.

Inside this post are 32 high-carb foods that athletes commonly use when preparing for training sessions, long workouts, or carb-loading before races.

Because fueling properly is just as important as the training itself.

Save this post so you have quick carb options when planning your training nutrition.

Protein Guide: Cheat Sheet

Protein is essential for muscle repair, recovery, metabolism, and overall health—especially if you’re active.

Most people benefit from around 1.2–2.0 g of protein per kg of body weight per day, with a practical target of ~30 g of protein per meal.

In this guide I’m sharing:
• Simple protein sources
• Plant-based options
• High-protein snack ideas
• Easy protein combos
• Some of my favorite protein brands

Whether you’re an athlete, training regularly, or just trying to eat better, getting enough protein consistently can make a big difference.

Need a quick boost before training?

If you’re eating within 30 minutes before a workout, simple carbohydrates are usually the best option. They digest quickly and give your body the energy it needs to perform.

Aim for about 20–40g of carbs and keep it easy to digest.

Some simple natural options include:
• Banana
• Dates
• Honey
• Fruit juice
• Rice cakes with banana
• Oats with maple syrup
• Grapes or dried fruit

Pre-training nutrition doesn’t have to be complicated. Small choices like this can make a big difference in energy, performance, and recovery.
