Your Nutritionist-Approved Hyrox Survival Guide

HYROX has become one of the most exciting new fitness challenges to take the world by storm. Combining 8 kilometres of running with 8 functional workout stations, it’s a hybrid event designed to test your strength, endurance, and mental grit. 

HYROX’s mix of high-intensity workouts has captured the attention of fitness enthusiasts and social media users alike. TikTok creators are sharing their HYROX experiences, gaining millions of views, and the event itself is seeing a surge in popularity, with search interest increasing by 279% in the past year and over 250k searches last month alone. 

But as appealing as the challenge is, HYROX is not your typical 5K race or CrossFit class—it’s an intense test of your overall fitness which requires thoughtful preparation. Nutrition expert Kyle Crowley here at Protein Works provides insights on how to safely prepare for HYROX, including training strategies, nutrition tips, and advice for first-timers.

Importance of ensuring safety

As more people are inspired by this type of workout, drawn to the sense of community and the challenge of pushing their limits, prioritising safety is highly advised. Crowley emphasises the importance of maintaining wellbeing:

“Proper nutrition, recovery, and being aware of the overall workload are crucial in ensuring the best approach. These aspects can often be overlooked on social media, where the focus tends to mainly be on the intensity of the challenge rather than the essential preparation and recovery needed to sustain it and avoid burnout.”

How to safely train for HYROX

Training for HYROX requires a balance between building strength and endurance, with a focus on functional movements. But if it’s your first time, starting slow is key. Kyle offers advice on how to best train for the race:

Start slow
“It’s easy to get excited and want to jump straight into the deep end, but I’d recommend beginners to start slow and work their way up. Rushing into high-intensity sessions without laying a foundation is a recipe for injury or burnout. Instead, spend time mastering the correct form for each of the HYROX exercises, such as sled pushes or wall balls. Proper technique will not only boost your performance but also keep you injury-free.”

Strength and endurance balance
“HYROX requires a mix of strength and cardiovascular fitness, so you need to train for both. Include compound strength movements like deadlifts, squats, and lunges in your training, but don’t forget about the cardio. Incorporate running to build the endurance you’ll need to power through those 1K intervals. The idea is to improve your stamina while also maintaining muscle strength to handle the workout stations.”

Interval training
“One of the best ways to prepare is to simulate the race in your training. This means combining running with functional exercises in interval-style workouts. Start by running shorter distances, followed by exercises like burpees or rowing, then gradually increase both the intensity and duration as your fitness improves. Interval training helps with stamina but also prepares you to switch between running and strength work—just like in HYROX.”

HYROX nutrition guide

Nutrition plays a crucial role in how well you perform and recover from HYROX. Whether you’re training or on race day, the food and fuel you put into your body can make or break your performance, Crowley advises.

Pre-race nutrition 

Carbohydrates are essential in the days leading up to the race. Slow-digesting carbs, like oats, quinoa, or sweet potatoes, should be a staple in your diet 24-48 hours before the race to make sure your glycogen stores are fully topped up. These will provide you with sustained energy throughout the event.”

Protein is equally important to support muscle function and recovery. Be sure to include lean protein sources like chicken, fish, or tofu alongside your carb intake. Additionally, monitor your calorie intake closely to avoid a large deficit. With the high level of movement and exercise in HYROX training, many underestimate how many calories they need—especially if new to this style of training. On average, a 45 to 90-minute interval session can burn between 400 to 1500 calories, so it’s crucial to fuel properly to sustain energy levels.”

Hydration is also key, and it’s not something you can leave until the last minute. Start hydrating a few days before the race, and consider electrolyte drinks. Proper hydration can prevent fatigue and cramping, both of which can ruin your performance on the day.”

“If you’re lifting heavier than usual in preparation for the race, supplements like creatine monohydrate or branched-chain amino acids (BCAAs) can help improve strength and muscle recovery, especially if you’re pushing your body beyond its normal limits.”

 During the race 

“On race day, aim to eat a balanced pre-workout meal around 3 hours before the start. You want a combination of carbs and protein, like brown rice with chicken or tofu. It’s enough to give you energy but won’t sit too heavily in your stomach.”

“For longer races like HYROX, keeping your energy levels up during the event is just as important. I recommend bringing along fast-digesting carbs, such as energy gels or sports drinks. These will provide quick energy boosts, especially when you start feeling fatigued during the later stages of the race. And, of course, keep hydrating. Sip water or an electrolyte drink throughout the race to maintain your hydration levels.”

Post-race recovery

“Post-race nutrition is all about recovery. Once you’ve finished, your muscles will be craving both protein and carbohydrates to repair and replenish. A protein shake with about 20-30g of protein, combined with some quick-digesting carbs like a banana or rice cakes, is a great post-race snack.”

“Follow this up with a balanced meal a couple of hours later. Think lean proteins like fish or chicken, complex carbs like quinoa or sweet potatoes, and healthy fats like avocados. This combination will help repair your muscles and restore energy levels.”

Tips for first-timers

As a first-timer, it’s important to approach HYROX with caution and respect for your body’s limits. “Your first HYROX is a learning experience, so it’s crucial to pace yourself,” Crowley advises.

Pace Yourself and listen to your body
“HYROX is a marathon, not a sprint. Many first-timers make the mistake of starting too fast, which can lead to burnout halfway through. Instead, focus on finding a steady, manageable pace. Save some energy for the later stages of the race, where fatigue is likely to kick in.”

“One of the biggest mistakes beginners make is ignoring their body’s signals. If you’re feeling fatigued, slow down. If something hurts, take a break. Pushing through pain or extreme exhaustion can lead to injury, which could set you back in your fitness journey.”

Focus on recovery and sleep
“Recovery is just as important as the training itself. After your race, give your body time to recover. Sleep is vital—make sure you’re getting 7-8 hours of rest, and incorporate foam rolling and stretching to help alleviate muscle soreness. Rest days are essential for preventing burnout and ensuring that your body comes back stronger.”

“Beyond nutrition, recovery should include activities like yoga, stretching, and proper warm-ups and cool-downs. These help relax muscles, improve flexibility, and prevent soreness or injury.”

Mind your form
“Proper technique is everything. When you’re fatigued, it’s easy to let your form slip, but that’s when injuries happen. For movements like sled pushes, lunges, and burpees, maintain proper form even when tired. Speed will come with practice, but safe and efficient movement is key for longevity in the sport.”

“Grip strength in particular is crucial—you can be strong but still struggle to hold the equipment without proper grip. Strengthening your grip through exercises like farmer’s carries or dead hangs will make a big difference. Focusing on technique is key to preventing injury and avoiding unnecessary fatigue from inefficient movement.”

Crowley concludes, “HYROX is an exciting, demanding event that pushes both your physical and mental limits. But with the right training, nutrition, and mindset, you can tackle your first HYROX race confidently and safely. Remember to pace yourself, fuel your body properly, and most importantly, enjoy the experience.”
