What Is HYROX? The Format, the Weights, and How to Train at Home

Somebody at your gym signed up for one. Then three more people did, and now half your feed is people in compression socks dragging a sled across a convention centre floor, and you still aren't completely sure what the event is. You have heard it described as CrossFit for runners and as a marathon for lifters, which are two different things and neither of them is right.

The confusing part is that HYROX looks like a specialist event and behaves like a generalist one. There's no skill to learn, no barbell to snatch, no bar to kip on. Every movement in it's something you could do on your first day in a gym. And yet people who can deadlift twice their bodyweight get taken apart by it, and so do people who run a 3:10 marathon.

That's because HYROX doesn't test one quality. It tests whether your engine and your strength survive contact with each other, over and over, for about ninety minutes. Once you understand the format, the training problem gets much simpler than it looks, and it turns out to be one you can solve at home.

What Is HYROX? The Format in One Paragraph

A HYROX race is eight 1 kilometre runs alternating with eight workout stations, always in the same order, at every event worldwide. You run 1 kilometre, do a station, run another kilometre, do the next station, and so on until the eighth run is followed by the eighth station and you're finished. That's 8 kilometres of running in total. Between the running lanes and the station area sits a transition zone called the Roxzone, and the clock doesn't stop while you're in it, so walking it slowly is a real and very common way to lose several minutes.

The standardisation is the whole point. Because the distances, reps and loads are identical everywhere, a HYROX time is a comparable number the way a marathon time is. That's unusual in fitness competition, and it's a large part of why the event has grown so fast. According to Athletech News reporting in July 2026, more than 1.5 million athletes raced in the 2025/26 season, and HYROX expects to pass 2 million athletes across 107 race weekends on six continents in 2026/27.

The eight stations, in order

Read that list again and notice what is missing. There's no barbell, no olympic lift, no pull-up bar, no handstand, no rope climb. Nothing on the list takes months to learn. The difficulty is entirely in the order, the volume and the fact that every station arrives after a kilometre of running and is followed by another one.

HYROX Divisions and Weights

Distances and reps stay the same for everyone. The loads are what change. Solo racers choose Open or Pro, and there are also doubles and relay categories for people who want to split the work. Per Red Bull's breakdown of the official division weights, the numbers look like this.

The pattern is worth memorising because it makes the jump obvious: Pro women lift exactly what Open men lift. If you're a woman weighing up Pro, the question isn't whether you're strong in the abstract, it's whether you can move the Open men's loads at the end of a kilometre. The SkiErg, the row and the burpee broad jumps carry no external load in any division, and the wall ball rep count stays at 100 across all four.

For the team categories, Open doubles uses the Open weights for the relevant gender, Pro doubles and mixed doubles both use the Pro women's loads, and relay teams race at Open weights. The Elite 15 field, the invitational professional race, uses Pro weights.

How Long Does a HYROX Race Take?

Longer than people expect, and slower than the highlight reels suggest. The most useful controlled data point comes from Brandt and colleagues (2025) in Frontiers in Physiology, who ran 11 recreational HYROX athletes through a full simulated competition. Median finish time was 86.5 minutes. Of that, 51.2 minutes was running and 32.8 minutes was station work. Peak heart rate hit 185 beats per minute, and blood lactate averaged 8.5 mmol/L during stations against 7.7 mmol/L during the runs.

At the sharp end, the times are brutal. Rappelt and colleagues (2026) analysed 39,696 PRO and ELITE results across the first seven competitive seasons, also in Frontiers in Physiology, and found the ELITE median dropped from 1:06:24 to 57:17 in men and from 1:11:09 to 1:03:22 in women over that span, with the coefficient of variation falling from over 10 percent to under 5 percent. The field is getting faster and tighter at the same time.

For a first race, plan on 90 minutes to two hours and treat finishing as the result. Third-party databases of race results put the all-participant average somewhere near 1:35 for men and 1:50 for women, but those figures lean fast, because the people who upload and analyse their splits are disproportionately the people who race repeatedly.

How HYROX Differs From CrossFit and Obstacle Races

These three get lumped together constantly, and they reward almost opposite training.

The practical difference is what you can prepare for. In CrossFit you train a wide skill base because you don't know which skills the event will ask for. In an obstacle race you train grip, terrain and the ability to restart running after a wall. In HYROX you know the exact task list a year in advance, which means the entire training problem is closing the gap between your current fitness and eight specific demands. That's a much friendlier problem, and it's the reason so many people who would never enter a CrossFit competition will enter this one.

What Fitness Does HYROX Actually Test?

Everyone assumes the stations decide the race. The data says the running does.

In the Rappelt analysis, running accounted for roughly half of total race time and showed the least rank reshuffling of any discipline, at 20.0 percent or less in men and 16.1 percent or less in women. In plain terms: your position in the running is close to your position overall. The strength stations produced more reshuffling, and their effect was strongest on slower athletes, which is the statistical version of a familiar race-day story, where the sleds and the wall balls are what blow a mid-pack time apart.

The Brandt simulated race points the same direction from a physiological angle. Across those 11 athletes, VO2 max correlated with finish time at rho = -0.71 and endurance training volume at rho = -0.68, while hand grip strength and muscle mass showed no significant correlation at all. The sample is small, so treat the exact numbers gently. The direction is what matters, and it lines up with the race-result data.

That doesn't make strength irrelevant. A review of HYROX's physiologic, mechanical and technical demands by Charlie Davids in the Strength and Conditioning Journal describes the aerobic system as foundational, since it's what lets you recover between efforts, with anaerobic power, local muscular endurance and maximal strength layered on top of it. Strength is the thing that keeps the sled from becoming a two minute problem. Aerobic fitness is the thing that keeps the other 80 minutes from becoming one.

The concurrent training question

If you train running and strength in the same week, do they cancel each other out? The honest answer is: much less than the gym folklore claims. In an updated meta-analysis in Sports Medicine, Schumann and colleagues (2022) found that adding endurance training to resistance training did not compromise gains in muscle hypertrophy or maximal strength, though explosive power adaptations were attenuated compared with resistance training alone. HYROX doesn't ask you to be explosive. It asks you to keep producing moderate force while breathing hard, which is exactly the combination that survives concurrent training best. We go through the full picture in our review of concurrent training and the interference effect.

The traffic runs in the other direction too. Blagrove, Howatson and Hayes (2018), reviewing strength training in middle and long distance runners, found that adding strength work improves running economy and time-trial performance without increasing body mass. For a race where you run 8 kilometres on legs that keep getting wrecked, better economy is worth more than it would be in a road 10K.

How to Train for HYROX at Home Without the Stations

You don't own a sled, a SkiErg, a rower or a 9 kilogram wall ball. That matters less than you would think, because the stations aren't skills, they're loads. What you need is a substitute that trains the same quality at the same duration. Do book two or three sessions in a gym that has the real machines before race day, not for fitness but so the rope, the handles and the sled feel familiar.

Two of those deserve a note. The farmers carry is the station that quietly ruins people, because grip fails before legs do and there's no way to fake it: our summary of the research on loaded carries covers why carries beat holds for trunk and grip work per minute spent. And the sandbag lunges land right after the sled push, so training them fresh teaches you nothing useful. Do them at the end of a session, on legs that are already tired, or you will be surprised on race day.

The bigger mistake is treating this as a strength programme with some running bolted on. Given that running is half the clock, your week should look like a runner's week with strength endurance inside it. Two easy runs, one harder run, two strength sessions, and one session that deliberately combines them.

The compromised running session

This is the one session that makes HYROX training different from running training, and it's free. Run 800 metres at a steady effort, do 60 seconds of one station substitute, then run 800 metres again, and repeat six to eight times. The point isn't the workout. The point is learning what your legs do in the first 200 metres after lunges, which is where almost every first-timer discovers that their goal pace was fiction. Pace it so the last run is the same speed as the first. If it's not, you started too fast, which is the same error people make in a tempo run and for the same reason.

A 12-Week HYROX Outline

This assumes you already run comfortably for 30 minutes and can do a full bodyweight squat. If you cannot, spend six weeks getting there first, because the plan below is a build, not a start.

Two guardrails keep the plan from turning into an injury. First, build running volume slowly: in a prospective study of 874 novice runners, Nielsen and colleagues (2014) found that raising weekly distance by more than 30 percent across a two-week window increased the rate of distance-related injuries such as patellofemoral pain and medial tibial stress syndrome. Your heart adapts in weeks, your tendons in months. Second, do the full simulation exactly once, and do it 12 to 14 days before the race. It's a race-hard effort, and treating it as a weekly session is how people arrive at the start line already flat.

If assembling the week yourself is the part that keeps not happening, a personalized training program handles the sequencing so you only have to show up. For the general aerobic base underneath all of this, our guide to increasing stamina covers how easy and hard days should divide a week, and the interval work sits comfortably inside a HIIT workout at home if you have no gym at all.

The Bottom Line

HYROX is eight kilometres of running with eight standardised strength stations wedged into it, run to the same specification everywhere on earth, and finished by most recreational athletes in 90 minutes to two hours. The research that exists puts running at roughly half the clock and aerobic capacity at the top of the list of things that predict a fast time, with strength endurance deciding how much the stations cost you.

Which is good news for anyone reading this from a living room. The version of this event that beats people isn't the version with the fanciest equipment. It's the version where someone trained the sled and forgot the eight kilometres.
