HYROX asks a simple question: how well can you keep performing when your legs are already cooked?

The race combines 8 x 1 km runs with eight functional workout stations, alternating between running and movements including the SkiErg, sled push, sled pull, burpee broad jumps, rowing, farmer’s carry, sandbag lunges and wall balls.

That combination makes HYROX different from a traditional road race, strength competition or functional fitness workout.

You need an engine.

You need strength.

And maybe most importantly, you need the ability to keep accessing both when fatigue starts piling up.

Training comes first. Nutrition, hydration, sleep and recovery build the foundation around it. Supplements can then help support the work you're already putting in.

Here’s how to approach both your HYROX training and your supplement stack.

What Does HYROX Training Need to Accomplish?

One of the easiest mistakes to make when preparing for HYROX is training exclusively with HYROX-style workouts.

More isn't always better.

Race simulations have their place, but preparing properly means developing the individual qualities the event demands and then teaching your body to put them together.

A balanced HYROX training program should include four major pillars.

1. Build Your Running Engine

Running accounts for 8 km of every HYROX race. HYROX itself describes running as roughly half of the event, so it shouldn't become an afterthought between strength sessions.

Your weekly training should include a combination of:

• Easy aerobic running to build your endurance base

• Tempo or threshold work to improve sustainable speed

• Intervals to develop higher-end aerobic capacity

• Race-specific running on fatigued legs

The goal isn't simply to become a faster runner.

It's to become a faster runner after pushing a sled, hammering the SkiErg or finishing 100 metres of lunges.

That's a different animal.

2. Get Strong Enough That the Stations Don't Own You

Pure strength won't win a HYROX race by itself, but insufficient strength can make several stations extremely expensive.

Sled pushes, sled pulls, farmer's carries and lunges all reward athletes with a strong strength foundation.

Prioritize movements such as:

• Squats and split squats

• Deadlifts and hinge variations

• Walking lunges

• Loaded carries

• Rows and pulling movements

• Sled pushes and pulls when equipment is available

The objective isn't necessarily to chase one-rep-max numbers.

You want enough strength reserve that competition loads feel manageable even as fatigue accumulates.

3. Train Strength Endurance

HYROX lives in the uncomfortable territory between endurance and strength.

Being able to move something heavy once isn't enough. You have to produce force repeatedly while your heart rate is elevated.

This is where movements like wall balls, lunges, carries and sled work become especially valuable.

Over time, introduce combinations such as:

1 km run → sled push → 1 km run

or

800 m run → farmer's carry → 800 m run → wall balls

These sessions teach you something isolated strength and running workouts can't: how to transition between modalities without completely falling apart.

That skill matters on race day.

4. Recover Hard Enough to Train Hard Again

HYROX training can create a substantial recovery demand.

You're combining running volume with resistance training, high-intensity conditioning and repetitive muscular work. If every session becomes a redline effort, progress can quickly become a slow-motion demolition project.

Recovery days, adequate calories, protein, carbohydrates, hydration and sleep aren't separate from your training program.

They're part of it.

And that's where a smart supplement strategy can support the bigger picture.

The ATP Lab HYROX Supplement Stack

A supplement stack shouldn't try to replace food, training or recovery.

Instead, think about what HYROX repeatedly demands:

Energy. Hydration. Muscular performance. Recovery. Repeat.

From there, the stack gets considerably simpler.

1. Electrolytes XL: Build Hydration Into Your Training

BEST FOR: DAILY HYDRATION + TRAINING

HYROX sessions can mean a lot of sweat, particularly during longer conditioning sessions, running workouts and race simulations.

ATP Lab Electrolytes XL 2.0 provides electrolytes including potassium, magnesium and calcium, along with zinc, beet root extract and coconut water. The formula is designed to provide a source of electrolytes while helping maintain normal muscle function and supporting energy metabolism.

For HYROX athletes, hydration shouldn't begin when the workout starts.

Make arriving at training well hydrated the default.

How it fits the stack: Use Electrolytes XL according to label directions as part of your daily hydration strategy, particularly around training and periods of higher sweat loss.

2. Pentacarb: Fuel the Longer Sessions

BEST FOR: HIGH-INTENSITY ENDURANCE + LONG HYROX SESSIONS

HYROX relies heavily on carbohydrates.

As training volume increases, adequate carbohydrate availability becomes increasingly important for sustaining high-intensity work.

ATP Lab Pentacarb is a carbohydrate and electrolyte formula designed to support energy production and help maintain performance and endurance during extended high-intensity exercise lasting more than 60 minutes.

That makes it particularly relevant for longer HYROX workouts, extended conditioning sessions and race simulations.

Think of carbohydrates as fuel in the tank.

You can have a powerful engine, but asking it to race on empty is rarely a winning strategy.

How it fits the stack: Use according to label directions when carbohydrate intake is appropriate for your training demands, particularly around longer and higher-output sessions.

Pentacarb has specific contraindications and warnings, including for people with diabetes, metabolic syndrome, insulin resistance or cardiovascular disease. Always review the product label before use.

3. Myoprime: Support Repeated High-Intensity Performance

BEST FOR: POWER + STRENGTH-FOCUSED TRAINING

HYROX may be an endurance event, but many of its decisive moments depend on your ability to repeatedly produce high levels of force.

That's where creatine becomes particularly interesting.

ATP Lab Myoprime is an advanced creatine formulation designed for intensive exercise. Its approved uses include helping improve physical performance during repeated bouts of brief, highly intense activity and supporting increased strength and power.

That translates well to the strength and power side of HYROX preparation, particularly sled training, heavy carries, resistance work and high-intensity intervals.

Creatine isn't something you need to "feel" during one workout. Consistent use is the bigger idea.

How it fits the stack: Follow Myoprime's label directions and recommended duration of use. Check the product's current label and cautions to determine whether it's appropriate for you.

4. Supreme Beef Protein: Give Recovery Some Building Material

BEST FOR: POST-WORKOUT + DAILY PROTEIN INTAKE

Training creates the stimulus.

Recovery builds the adaptation.

Getting enough high-quality protein throughout the day helps provide the amino acids required to build and repair body tissues.

ATP Lab Supreme Beef Protein delivers 24 g of protein per scoop from beef bone broth and hydrolyzed grass-fed beef collagen. It's dairy-free and provides a complete amino acid profile. ATP Lab positions it as an athletic-support protein that helps build and repair body tissues and provides amino acids involved in muscle protein synthesis.

For an athlete balancing several running and strength sessions each week, convenience matters.

A shake won't replace a good meal, but it can make hitting your daily protein target considerably easier.

How it fits the stack: Use it to help fill gaps in your daily protein intake, including after training when convenient.

5. Synermag: Support Muscle Function Behind the Scenes

BEST FOR: DAILY FOUNDATION + RECOVERY

Magnesium doesn't get the same pre-workout spotlight as carbohydrates or creatine.

That's partly why it's worth paying attention to.

Magnesium participates in numerous physiological processes involved in normal muscle and energy function.

ATP Lab Synermag combines magnesium bisglycinate and magnesium malate with taurine and vitamin B6. Its approved uses include helping maintain proper muscle function, normal electrolyte balance and energy metabolism.

For an athlete stacking running, strength work and conditioning across the week, those fundamental processes matter.

How it fits the stack: Take Synermag consistently according to label directions rather than thinking about it exclusively as a workout-day supplement.

6. Syner Collagen: An Optional Addition for Connective Tissue Support

BEST FOR: HIGH TRAINING VOLUMES + JOINT SUPPORT

Running.

Sleds.

Burpees.

Lunges.

More running.

HYROX training produces plenty of repetitive mechanical stress, which makes connective tissue health another piece of the long-term performance puzzle.

ATP Lab Syner Collagen is formulated to support connective tissue formation and joint health. Its formulation includes hydrolyzed collagen alongside other supporting ingredients including vitamin C.

It can be considered as an additional layer for athletes looking to support connective tissues alongside appropriate programming, nutrition and recovery.

How it fits the stack: Use consistently according to the product's recommended dosage.

Putting It Together: A Simple HYROX Supplement Routine

You don't need to carry half the supplement cabinet into the gym.

Keep the fundamentals simple.

DAILY

Synermag
Support normal muscle function, electrolyte balance and energy metabolism.

Supreme Beef Protein
Use as needed to help reach your daily protein target.

Myoprime
For athletes using creatine as part of their performance program, take consistently according to label directions.

BEFORE / AROUND TRAINING

Electrolytes XL
Support hydration and electrolyte intake.

LONG OR HIGH-INTENSITY SESSIONS

Pentacarb
Add carbohydrate support when training duration and intensity justify it.

OPTIONAL DAILY SUPPORT

Syner Collagen
Add when connective tissue and joint support are priorities.

What About Race Day?

Race day is not the time to become your own nutritional science experiment.

Whatever hydration and fueling strategy you're planning to use should already have been tested during training.

In the weeks leading into competition, rehearse:

• Your pre-race meal

• Your hydration strategy

• Your carbohydrate intake

• Your supplement timing

• Your caffeine intake, if applicable

• Your warm-up

• Even how much fluid your stomach tolerates while running

Nothing new on race morning.

You've already got sleds, SkiErgs, lunges and wall balls waiting for you. Your stomach doesn't need to join the competition.

The Bottom Line

HYROX rewards athletes who can do a little bit of everything extremely well.

Build your aerobic engine.

Develop enough strength to control the stations instead of merely surviving them.

Practice running under fatigue.

Fuel the work.

Hydrate properly.

Recover deliberately.

Then use supplementation to support those fundamentals, not replace them.

Because the best HYROX stack is ultimately the one that helps you consistently do the thing that matters most:

Train. Recover. Adapt. Repeat.

Always follow product label directions. Individual nutritional and supplementation requirements vary. Consult a qualified healthcare professional before using supplements if you have a medical condition, take medication, are pregnant or breastfeeding, or have questions about whether a product is appropriate for you.
