HYROX has taken the global fitness scene by storm — and New Zealand athletes are diving head-first into this hybrid fitness challenge. As the sport grows, so does the demand for performance-driven supplementation. Whether you’re chasing your first HYROX finish or gunning for a podium spot, the right nutritional support can be a game-changer.
In this guide, we break down the best supplements for HYROX, why they matter, and how to incorporate them into your training.
What is HYROX?
HYROX is a fitness competition designed to test both strength and endurance. Each event follows the same global format: 8 x 1km runs, each followed by a functional workout station — think sled pushes, rowing, wall balls, and more. It’s the ultimate test of hybrid athleticism, demanding both cardiovascular stamina and muscular resilience.
Unlike CrossFit, HYROX is standardised across the world, meaning every competitor does the same workout under the same rules. This makes it an ideal training target for competitive and recreational athletes alike.
What Supplements Should I Take for HYROX Training?
HYROX demands sustained energy, fast recovery, muscular endurance, and hydration. Because of this, athletes need a supplement stack that covers both endurance and power output. Here are the top 5 HYROX supplements that deliver on all fronts:
- Creatine
- Carbohydrates
- Protein Powder
- Beta-Alanine
- Electrolytes
1. Creatine — Explosive Strength and Power Output
Creatine is one of the most researched and reliable supplements on the market. It’s known for improving explosive strength, short-burst power, and muscle endurance — all critical in movements like sled pushes, burpee broad jumps, and sandbag lunges.
Benefits for HYROX athletes:
- Boosts ATP production for fast energy output
- Improves strength for sled-based and weighted stations
- Supports muscle hydration and recovery
How to take it: 5g daily (with or without a loading phase).
2. Carbohydrates — Fuel Your Runs and Stations
Carbs are your primary fuel source during HYROX. Unlike keto or low-carb diets that favour fat adaptation, HYROX is a glycogen-burning machine. Supplementing with fast-digesting carbs around training and competition keeps your engine running strong.
Benefits for HYROX athletes:
- Replenishes muscle glycogen quickly
- Boosts endurance during long sessions
- Reduces fatigue mid-event
How to take it: 30–60g pre- or intra-workout, especially for longer sessions.
3. Protein Powder — Recovery and Muscle Support
Recovery is half the battle — especially in HYROX training where the workload is high and rest days are few. A clean protein powder helps you repair muscle damage, rebuild tissue, and maintain lean mass during cutting or performance phases.
Benefits for HYROX athletes:
- Speeds up post-workout muscle recovery
- Reduces soreness and muscle breakdown
- Supports lean mass maintenance
How to take it: 25–30g within 30–60 mins after training or as a daily snack.
4. Beta-Alanine — Buffer Fatigue and Boost Endurance
That burning sensation in your legs during a wall ball set or a row sprint? That’s hydrogen ion build-up — and beta-alanine helps buffer it. By increasing carnosine levels in your muscles, beta-alanine delays fatigue, allowing you to push harder, longer.
Benefits for HYROX athletes:
- Increases anaerobic endurance
- Reduces lactic acid build-up
- Helps maintain high intensity across stations
How to take it: 3.2–6.4g daily. Split doses if needed to minimise tingling.
5. Electrolytes — Hydration for Peak Performance
Hydration isn’t just about water — it's about electrolytes: sodium, potassium, magnesium, and calcium. During HYROX, you’re sweating hard. Replacing lost minerals keeps your nervous system firing, muscles contracting, and cramps at bay.
Benefits for HYROX athletes:
- Replenishes minerals lost through sweat
- Supports muscle contractions and nerve function
- Improves hydration and endurance
How to take it: Use in your water pre-, intra-, and post-training. Consider higher sodium blends for hot sessions or long events.
Putting It All Together — Your HYROX Supplement Stack
Here’s how a typical HYROX athlete might structure their daily stack:
Morning / Pre-Workout: Beta-Alanine + Creatine + Carbohydrates + Electrolytes
Intra-Workout: Electrolytes + Carbohydrates
Post-Workout: Protein Powder + Creatine
Evening: Beta-Alanine (if dosing twice daily)
This routine supports both performance and recovery, making it easier to train consistently without burnout.
Final Thoughts: Why These Are the Best Supplements for HYROX
HYROX is not just another race — it’s a test of functional fitness, mental toughness, and physical endurance. To thrive in training and competition, your nutrition and supplementation need to be on point. That means fuel before, hydrate during, and recover after — and these 5 supplements cover all three.
Whether you're new to the scene or chasing your next PB, investing in high-quality HYROX supplements NZ will help you stay strong, finish fast, and recover smarter.
