Hyrox: What It Is, Why It's Everywhere, and How to Fuel It Properly

If you've been anywhere near a gym in the past couple of years, you'll have heard about Hyrox. It's showing up on social feeds, inspiring gym classes and weekend plans with equal intensity. And with over a million athletes expected to compete globally across more than 85 cities this season alone, it's clear this isn't a passing trend - it's a full-blown fitness movement. But what actually is Hyrox? And more importantly, if you're training for one (or thinking about it) what does your nutrition need to look like to make sure you actually perform on race day? Let's break it down.
So, What Is Hyrox?
Hyrox is a global fitness race built around a deceptively simple format: 8 x 1km runs, each followed by one functional workout station. That's eight rounds of running, eight rounds of work. The eight stations are always the same, always in the same order:
• 1,000m SkiErg
• 50m Sled Push
• 50m Sled Pull
• 80m Burpee Broad Jumps
• 1,000m Rowing
• 200m Farmers Carry
• 100m Sandbag Lunges
• Wall Balls (75-100 reps depending on category)
The format is standardised across every event in every country, which means your time is comparable globally - and that consistency is a huge part of the appeal. Whether you're entering the Open category as a first-timer or lining up in the Pro division with heavier loads, every athlete is working the same course.
It's also one of the few formats where everyday gym-goers and elite athletes share the same floor. That accessibility combined with the competitive edge is exactly why Hyrox has seen a 5,614% surge in UK participation since 2021.

Why Hyrox Is Different (And Why That Matters for Your Fuelling)
Hyrox sits squarely in the crossover between endurance and strength - it's not a marathon and it's not a gym session; it's both, back-to-back, for 60–90+ minutes. That hybrid demand changes everything when it comes to how you fuel.
During a Hyrox race, your body is cycling between aerobic steady-state running and short, intense anaerobic bursts at each station. Your muscles need sustained energy over a long effort, but also quick-access fuel for the power stations. If you're under-fuelled, you'll feel it - usually around the rowing or the lunges. If your recovery between sessions has been poor, you'll feel that too.
The good news? Sorting your nutrition doesn't need to be complicated. It needs to be real, consistent, and built around food that actually works.

Fuelling Hyrox Training: What to Eat and When
Before Training - Pre-session nutrition is about giving your body the energy to perform without sitting heavy in your stomach. You need carbohydrates for fuel and protein to protect your muscle tissue during the effort. A bowl of Acti-Snack granola 60-90 minutes before training is a solid, no-faff option. The Peanut Butter Protein Crunch Granola is particularly well-suited - it's packed with slow-release oats, packed with protein from the peanuts, and won't give you the energy spike and crash that most sports-branded products serve up. It's real food that works hard.
During Training - For most Hyrox training sessions, you won't need to fuel mid-session. But if you're doing longer simulation runs (90 minutes or more) or back-to-back sessions, having something small and easy to digest can make a real difference to how you finish. Acti-Snack trail mixes are ideal here - small, portable, and built around real ingredients like nuts, seeds, and dried fruit that deliver both fast and slow-release energy. No artificial sweeteners, no unnecessary additives. Just food that keeps you moving.
After Training - Recovery is where Hyrox is actually won. The quality of your adaptation between sessions depends on how well you refuel afterwards - and the two-hour window post-training is critical for protein synthesis and glycogen replenishment. Reach for a recovery snack within 30-60 minutes of finishing. A combination of protein and carbohydrates is the target - and again, the Peanut Butter Protein Crunch Granola works well here, whether that's as a bowl with milk or a quick handful straight from the bag if you're short on time.

Race Day: Fuelling the Full 8 Rounds
Race day is not the day to try something new. Your fuelling strategy should mirror what you've been doing in training i.e. familiar foods, familiar timing, no surprises.
A solid race day nutrition plan might look like this:
•Night before: Higher carbohydrate dinner to top up glycogen stores. A bowl of Acti-Snack granola before bed isn't a bad shout either as oats are slow-releasing, which means you're still drawing on that energy come morning.
•Race morning (2-3 hours out): A full breakfast built around complex carbohydrates and protein. Granola with yoghurt and fruit is easy to digest, energy-dense, and genuinely enjoyable which is important when nerves are already doing their thing.
•30 minutes before start: Something small if needed - a trail mix portion or a handful of nuts to keep blood sugar stable without overloading your stomach.
•Post-race: Get protein and carbohydrates in as quickly as possible. Your muscles will be asking for it. A familiar snack from Acti-Snack is a good bridge before you get to a proper meal.
One thing worth calling out: don't neglect hydration. Hyrox is an indoor event, which means heat builds quickly. Drink consistently in the days before and sip water at every opportunity on race day. Performance drops significantly even at mild levels of dehydration, and no amount of good food will compensate.

The Bigger Picture: Nutrition as a Training Habit
One of the most common mistakes Hyrox athletes make, especially those coming from a pure gym background, is treating nutrition as an afterthought. They train hard, sleep well, and then grab whatever's convenient when it comes to food. But Hyrox demands consistency across all three. Your eight stations aren't just a test of what you did in the gym last week - they're a test of how well you've looked after yourself across an entire training block.
Building real food habits around training rather than relying on processed bars and synthetic supplements is one of the simplest ways to support better performance and faster recovery. Acti-Snack exists exactly for this: food made from honest ingredients that pulls its weight when it matters.
Whether you're twelve weeks out from your first Hyrox or you've got a PB to chase, getting your nutrition right isn't about being perfect - it's about being consistent. Start with what you eat every day, make it work harder for you, and build from there.
