You have probably seen it on your Instagram feed. Someone you follow crossing a finish line looking absolutely wrecked but somehow grinning from ear to ear. A leaderboard. A sled. A lot of sweat. The word HYROX in big bold letters somewhere in the background.
That is not a coincidence. Hyrox has gone from a niche fitness event dreamed up in Hamburg in 2017 with fewer than 700 athletes to a full-blown global phenomenon attracting over 650,000 competitors in 2024 alone. Tickets sell out in minutes. London now operates a ballot system with over 70,000 people applying for 16,000 spots. New York sold out in 40 minutes. Time magazine named it one of the most influential companies of 2024.
So what on earth is going on? And more importantly, if you are a runner, why should you care?
Take a look at the Ultimate Fitness and Hyrox Running Training Guide
So what actually is Hyrox?
Hyrox is a standardised fitness race. Every single event, in every single city, in every single country, follows exactly the same format. Eight one-kilometre runs, each followed by a functional fitness station. That is it. Simple enough to explain. Absolutely punishing to do.
The format looks like this:
1km run, then Ski Erg (1km) 1km run, then Sled Push (50m) 1km run, then Sled Pull (50m) 1km run, then Burpee Broad Jumps (80m) 1km run, then Rowing (1km) 1km run, then Farmers Carry (200m with kettlebells) 1km run, then Sandbag Lunges (100m) 1km run, then Wall Balls (100 reps)
That is 8km of running sandwiched around 8 workout stations. Average finish time is around 90 minutes for recreational athletes and around 60 minutes for the seriously fit. And here is the thing: 98% of people who start a Hyrox finish it. There is no time limit. That finish-line photo is basically guaranteed. Which is part of why everyone keeps signing up.
Why is everyone suddenly obsessed with it?
A few things happened at once that made Hyrox absolutely explode.
First, the format is genius. It is standardised, which means your time in London is directly comparable to someone's time in Tokyo or Chicago. That creates genuine competition, personal bests and a reason to keep coming back and improve. In a world where so much gym training feels formless, Hyrox gives it a scoreboard.
Second, it sits perfectly in the middle of the fitness world. Runners who do not lift. Gym-goers who do not run. CrossFitters. Triathletes. Pilates people who got curious. Hyrox welcomes all of them and punishes none of them too harshly. With categories including Open, Doubles, Relay and Pro, there is genuinely a version for everyone from complete beginners to elite athletes.
Third and let's be honest, it was built to go viral. Indoor venues packed with athletes, DJs pumping music, incredible photography and a format that is endlessly shareable. The hashtag #hyrox has racked up tens of millions of views on TikTok. Hyrox's Instagram has 450,000 followers and counting. The social media flywheel is spinning fast.
The growth numbers back it up. From 650 athletes at the first event in 2017 to over one million expected participants in the 2025 to 2026 season. A 1,000% increase in global participation in five years. Revenue projected at $140 million in 2025. Over 5,000 gyms worldwide now certified as Hyrox Training Clubs. This is not a trend. It is a sport.
The eight workout stations explained
Here is what you are actually doing between the runs:
Ski Erg: A standing rowing machine that works the arms, shoulders and core. It is the first station, which is both a relief and a trap because you go in feeling fresh and go too hard.
Sled Push: You push a weighted sled 50 metres. It is low skill, high pain, and it absolutely torches your legs before you have to run again.
Sled Pull: Same sled, same 50 metres, but now you are pulling it towards you using a rope. Your forearms will remember this one.
Burpee Broad Jumps: 80 metres of burpees where you jump forward rather than up. One of the most hated stations on the course. The floor is your friend and also your enemy.
Rowing: 1,000 metres on a Concept 2 rower. By this point your legs already have a lot of opinions about everything. The rowing does not care.
Farmers Carry: You pick up two kettlebells and walk 200 metres. Sounds fine. Is not fine.
Sandbag Lunges: 100 metres of lunges carrying a sandbag. This is the station that ends friendships. Your quads will be having a full breakdown by this point, and then you have to run again.
Wall Balls: 100 reps of throwing a medicine ball at a target on the wall. The final station before the finish line. This is where you find out what you are made of.
Who is Hyrox actually for?
Everyone, genuinely. That is not marketing fluff, it is actually true.
Over 65% of Hyrox competitors are aged over 30. The oldest finisher on record is 74. Around 38% of competitors are female, a number growing fast. Roughly 70% of people at any given Hyrox event are doing it for the first time.
You do not need to be an elite athlete. You do not need specialist equipment. You do not need to have done CrossFit or run marathons. You just need to be willing to train properly for it and comfortable with the idea of hurting a bit on race day. Both of those things, it turns out, runners are extremely good at.
Why runners have a massive built-in advantage
Here is the part where runners sit up a bit straighter.
Hyrox is 50% running. Eight kilometres of it, distributed across the whole race. And here is the crucial thing that catches gym athletes completely off guard: the running in Hyrox is not like running a fresh 8km. Every single kilometre happens in a state of pre-fatigue. You run off the back of a sled push with your legs screaming. You run after 80 metres of burpees with your lungs on fire. You run after sandbag lunges when your quads are basically refusing to participate in further discussions.
This is exactly where runners have a massive structural advantage. Running training builds the aerobic engine, the running economy and the mental toughness that Hyrox absolutely demands. Gym athletes who can destroy the workout stations often fall apart on the runs because their aerobic capacity cannot sustain the pace. Runners feel right at home.
The running in Hyrox: why it matters more than people think
Running economy
Running economy, which is essentially how efficiently your body uses energy at a given pace, is one of the biggest predictors of Hyrox performance. The more economical your running, the less energy you burn on each kilometre and the more you have left for the stations.
Runners who have trained properly develop this efficiency over months and years. It is baked in. Understanding what running cadence means and how to improve it is directly relevant here, because efficient turnover and foot strike become even more important when your legs are heavy and your form is under pressure.
Research on Hyrox performance consistently shows that athletes who maintain better running form under fatigue outperform those whose mechanics break down in the later stages. Runners have spent hundreds of hours practising exactly that.
Pacing under fatigue
Elite Hyrox finishers at the World Championships have shown only a six-second difference between their fastest and slowest 1km splits across the whole race. That level of pacing control is not accidental. It is a skill built through consistent training.
Runners who have practised pacing their runs and learned to manage effort through feel rather than just going on instinct are already ahead. The biggest mistake in Hyrox is going out too fast on the first few runs and paying for it dearly in the second half of the race. This is a lesson every experienced runner already knows.
Mental toughness
Running builds a very specific kind of mental resilience. The ability to sit with discomfort, to push through the voice that says stop, to keep going when your body is genuinely protesting. Hyrox lives in exactly that space.
The mental health and resilience benefits of running translate directly to Hyrox performance in a way that is difficult to quantify but impossible to miss on race day.
How to use your running training to prepare for Hyrox
If you are a runner thinking about Hyrox, here is the great news: you are probably already doing most of the right things. Here is how your existing training maps onto Hyrox preparation.
Your long runs build the aerobic base. A strong aerobic engine is the foundation of everything in Hyrox. It determines how well you recover between stations, how consistently you can pace the runs and how much you have left in the tank for the final wall balls. Keep doing your long easy runs. They are doing more for your Hyrox prep than you might think. Understanding why easy running helps you run faster applies just as much to Hyrox as it does to a 10K.
Your interval sessions build race-specific speed. Interval training improves your VO2 max, your ability to recover between hard efforts and your tolerance for running at uncomfortable intensities. In Hyrox, every run starts in a state of partial recovery from the previous station. Intervals train your body to handle exactly that kind of repeated hard effort.
Your tempo runs build threshold fitness. Hyrox running pace sits right around lactate threshold for most athletes, which is that comfortably hard effort you can sustain but not hold a conversation at. Tempo runs train your body to clear lactate faster, delay fatigue and hold pace when things get tough. This is the Runna guide on the ultimate functional fitness and Hyrox running training guide if you want the full breakdown.
Add compromised running to your sessions. This is the one thing runners need to add that they probably are not doing already. Compromised running means going straight from a hard exercise into a run, simulating what happens in a Hyrox race. Do a hard set of lunges and then immediately run 1km. Do a set of burpees and go straight into a fast kilometre. This trains your body to maintain running economy when your legs are already loaded, which is the defining skill of a good Hyrox athlete.
What runners need to add to be Hyrox-ready
Your running fitness is a huge advantage but Hyrox will expose any gaps in your strength. Here is what to focus on:
Leg strength. Squats, lunges, deadlifts and hip thrusts will help you survive the sled work and sandbag lunges without destroying your running in the second half. Strength training for runners is your starting point here.
Upper body and pulling strength. The ski erg, sled pull and farmers carry all demand upper body endurance that running does not develop. Add some rows, pull-downs and carries into your routine.
Core stability. A strong core keeps your running form together under fatigue and powers every station efficiently. Pilates training for runners is brilliant for building this without adding muscle bulk that slows you down.
Should you give Hyrox a go?
If you are a runner who has been eyeing Hyrox from a safe distance wondering if it is for you, the answer is almost certainly yes.
Your aerobic base, your pacing instincts, your mental toughness and your running economy are all things that Hyrox rewards enormously. You will need to fill in the strength gaps, learn the stations and do some compromised running in training. But you are starting from a position of genuine advantage.
The 98% finish rate means the pressure to perform is low. The format means the opportunity to improve is limitless. And the community around Hyrox is, by most accounts, one of the most welcoming and energetic in sport right now.
One word of warning though: virtually everyone who does their first Hyrox immediately books their second. You have been warned.
The bottom line
Hyrox is not a trend. It is a sport, and it is growing faster than almost anything else in the fitness world right now. For runners, it is one of the most exciting and accessible ways to test your fitness in a new arena, with a built-in advantage that gym-only athletes simply do not have.
Build your aerobic base, sharpen your running with a personalised Runna training plan, add in some strength work and compromised running sessions, and you will be more than ready to get on that start line.
Now go find a Hyrox near you. Just do not say we did not warn you about the sandbag lunges.
