- The race is eight rounds, each a 1 km run followed by one functional workout station, so a runner's existing base covers the larger share of the clock and none of the rest.
- Brandt and colleagues, in the only published physiological study of a HYROX race, found aerobic fitness was the strongest correlate of finishing time, and found no correlation between athlete characteristics and time spent on the stations.
- In the Brandt 2025 HYROX study of eleven recreational athletes, the three most heavily loaded stations were the three fastest to complete.
- A marathoner and a 5k runner arrive at HYROX with opposite problems, so the first training change is different for each.
- Two evidence sources give different strength-frequency prescriptions for runners, and which one applies depends on how many days a week a runner already runs.
You already have the engine. That is worth more in HYROX than in almost any other fitness race, and it is also why runners prepare badly for it: the part they are good at is the part they keep training. This page is not a weekly schedule. It is a diagnosis. It tells you which parts of your running background transfer, which parts mislead you, and what to change first.
What your running base actually buys you, and what it does not
The one study anyone has run on this
There is exactly one published physiological study of a HYROX race: Brandt, Ebel, Lebahn and Schmidt, in Frontiers in Physiology in 2025. Eleven recreational athletes completed a simulated race run to Individual Open standards, after a lab pre-test measuring body composition and maximum oxygen consumption. Eleven people, one simulation, one division. Treat every figure below as a first measurement, because there is no second study to check it against.
Faster overall times went with higher aerobic fitness, and that was the strongest association the researchers measured. Endurance training volume came next, body fat percentage after that. Then the half that flatters nobody: analysed separately, the correlations with athlete characteristics showed up only for the runs. For the stations, nothing. Muscle mass percentage did not predict performance, and neither did resistance training volume.
Both halves matter. Your engine is the best predictor of finish time in the only data that exists, and it predicts nothing about what happens between the runs. Those athletes spent a median of just over fifty minutes running and just under thirty-three on the stations, out of a median finish near eighty-six and a half minutes. Running was the bigger block, never the whole race.
Why the heaviest stations were the fastest
Runners look at the sled loads and assume that is where the time goes. In the Brandt study the three shortest median station times belonged to the sled push, the sled pull and the farmers carry: the three heaviest loaded stations on the floor. The longest single blocks of time were runs.
The heavy stations are brutal and brief. They do not consume the clock, they wreck the run that follows. Asked to rate their own effort, the athletes in that study scored the stations as significantly more strenuous than the runs. The highest heart rate, blood lactate and exertion values of the whole race arrived at the last station, the wall balls. The loads will not cost you the minutes you expect. They will cost you minutes somewhere else.
What this page covers, and what it does not
No weekly schedule here, no session mix, no prescribed workouts. Those already exist: volume bands, session types and progression live in our HYROX running plan, and the whole training picture sits in the HYROX training hub. This page sorts you by where your running came from and names the one change worth making first.
HYROX training for runners: the decision table
Every generic answer assumes one runner. There is no one runner. An athlete three weeks out of a marathon block and a track 5k runner share the word and nothing else. Find your row.
| Where you are coming from | Your likely limiter | What already transfers | Change this first | The trap for your type |
|---|---|---|---|---|
| Just finished a marathon or half block | Structural freshness, not fitness. Deep base on legs that absorbed months of repetitive load. | Almost all of the running half. Aerobic capacity was the strongest correlate of total time in the only published study. | Recovery weeks first, then two full-body strength sessions before any station work. Do not stack a HYROX block onto a marathon block. | Treating the fitness as a licence to skip the rebuild. The fitness is banked and the tissue is not. |
| 5k or 10k road or track runner | Muscular endurance and load tolerance. High pace, low volume, little lifting. | Pace judgement, threshold work, mechanics. Your race-pace discipline beats most first-timers'. | Lunges and loaded carries. The stations that wreck your race are 100 m of walking lunges and 200 m of carrying. | Racing the opening leg. Your 5k instincts will cash the whole race in the first run. |
| Trail or ultra runner | Sustained upper-body work and grip. Your legs are the least of your problems. | Time on feet, fatigue tolerance, pacing over rough ground, a high ceiling for training load. | Pulling volume: rows, pull-downs, hangs, sled-pull practice. The pull is what your background prepares you for least. | Assuming volume solves it. More running on a large base buys nothing and costs recovery you need elsewhere. |
| Triathlete | Specificity, not capacity. Three modalities already on one recovery budget. | The most of any background: transitions, brick sessions, erg familiarity, upper-body pulling. | Lower-body strength under external load. Cycling and swimming build capacity without teaching legs to move a sled. | Under-respecting the loads because the engine is strong. The sleds do not care about your FTP. |
| Runs three or fewer days a week and already lifts | Running volume, and running on tired legs in particular. | Strength for every station. Open loads will feel manageable. | Running frequency, then run-into-station transitions. You need the economy, not more strength. | Believing the stations carry you. Running was the larger share of the clock in the published study. |
| Runs six or more days a week and cannot add sessions | Time and recovery, not capacity. | Everything aerobic. | Convert, do not add. Replace one easy run with erg work, one with a run-into-station session. Brandt and colleagues recommend substituting rowing or skiing to avoid the injury cost of more mileage. | Adding strength on top of a full week and losing both. This is the row where the two evidence sources disagree. |
Plenty of runners sit between two rows. Take the limiter from the row that describes your last three months and the first change from the row that describes your next three. If both genuinely apply, do the change furthest from your habit, because that is the one you would skip.
If your last hard session told you something
A more direct route in. Match what happened, not what you think your weakness is.
| What happened in your last hard session | What that points at | The first thing to change |
|---|---|---|
| Pace fell off a cliff for two hundred metres after a heavy effort, then came back | Transition mechanics, not fitness | Rehearsed run into a station and out into a run. Not more mileage. |
| Forearms and hands gave out before the legs did | Grip endurance | Loaded carries and hangs, twice a week |
| Quads were the limiter and breathing was fine | Strength endurance under load | Walking lunges under load, plus eccentric-biased leg work |
| Breathing was the limiter and legs felt fine | Aerobic ceiling at station intensity | Threshold work, and intervals that finish on a station |
| Fine until the last two rounds, then nothing worked | Pacing, not any physical quality | Effort discipline early. Read the pacing guide rather than adding training. |
The four things no running background covers
None of what follows is a study finding. It is coaching reasoning about four gaps that steady running leaves open.
Running on legs a station just taxed
Only the opening leg is run on fresh legs. Every one after starts on a body that has just done something heavy, and the pace you can hold then has little to do with the pace on your watch. What a station does to the run that follows it is covered in our guide to compromised running. Read it once, then go rehearse it.
Grip and upper-back endurance
For most runners the binding constraint on the pulling stations is the hands and the upper back, not the legs or the lungs. The farmers carry runs over 200 m, and section 8.6 of the Singles rulebook does permit putting the kettlebells down to rest, so long as they do not move forward when you place them. Every set-down still costs you time and a re-grip. The sled pull asks for repeated hand-over-hand work from the same pair of hands. Nothing in a running week trains either, and that is coaching reasoning rather than a research finding.
Lunging under load
The sandbag runs for 100 m of walking lunges, carried across both shoulders, deep in the back half of the race. It is an eccentric-heavy hip and knee pattern with a load on your spine, and steady-state running trains none of it.
Horizontal force into a sled
Running propels you by pushing down and springing. A sled asks for sustained horizontal force against something that does not give. The push covers 50 m in total, broken into 4 x 12.5 m shuttles, so the effort restarts from a dead stop each time. Practising it is the only thing that teaches it.
Fitting strength around running without losing the running
What the evidence says about adding strength
Blagrove, Howatson and Hayes reviewed twenty-four studies of strength training in middle- and long-distance runners. Their key points state that strength training appears to benefit running economy, time trial performance and maximal sprint speed in runners of all abilities, and that maximal oxygen uptake, blood lactate parameters and body composition appear unaffected by adding it. Running economy was measured in twenty of those studies and generally improved by two to eight percent against a control group, though the authors are explicit that this was not the case every time. Keep that hedge.
Where the two sources part company on frequency
Blagrove and colleagues state that adding strength training on two to three occasions per week is likely to positively affect performance. That is an absolute count, and it does not move with how much you run.
Brandt and colleagues, in the HYROX study's training recommendations, report a different frame taken from a concurrent-training review by Methenitis: for optimal endurance adaptations, a resistance-to-endurance frequency ratio of 1:1 or 1:2, and for optimal resistance adaptations, a ratio of 2:1 or 3:1. That is a ratio, and it moves with your running frequency.
These are not the same prescription and should not be merged. At three running days a week they coincide at roughly three strength sessions. At six they diverge sharply: the ratio frame permits three at 1:2 and six at 1:1, while the absolute frame caps at three however much you run. If you are in the high-volume group that divergence is your call, and the safer read is the lower of the two. What to actually lift is answered in our guide to HYROX strength training.
Order within a session, and what order does not fix
Ten studies on exercise sequence were pooled by Eddens, van Someren and Howatson. Lifting before endurance work produced a benefit for lower-body dynamic strength compared with the reverse order, a weighted mean difference near seven percent. There was no effect of sequence on maximal aerobic capacity, hypertrophy, static strength or body fat percentage, and the authors concluded an order effect showed up for one outcome only. So the claim is narrow: lifting first protects the lift. What it measured was adaptation across programmes of five weeks or more, not the quality of a single run on the day, so it cannot settle that question either way. Our HYROX strength training guide takes the practical line of running first when the run is the priority and both have to share a session. Putting them on separate days removes the tradeoff rather than picking a side of it.
If you cannot add sessions, convert them
Brandt and colleagues make a specific recommendation for this case: since athletes spend most of the race running, a substantial share of training volume has to go to running-based work, but excessive mileage raises injury risk, and a strategy to avoid that is replacing or combining running with other HYROX-specific endurance work such as rowing or skiing. They add that combining running with other HYROX movements should be integral, to build running economy in a pre-fatigued state.
Both ergs are on the course anyway. The row is 1000 m, and the SkiErg is 1000 m. Swapping one easy run for erg work costs you nothing aerobically, buys back some structural load, and rehearses two stations while you are at it.
The loads you will actually meet
Open division loads, from the official Season 26/27 rulebook.
| Station | Open Women | Open Men | Distance |
|---|---|---|---|
| Sled Push | 225 lb (102 kg) | 335 lb (152 kg) | 50 m |
| Sled Pull | 172 lb (78 kg) | 227 lb (103 kg) | 50 m |
| Farmers Carry | 2 x 35 lb (16 kg) | 2 x 53 lb (24 kg) | 200 m |
| Sandbag Lunges | 22 lb (10 kg) | 44 lb (20 kg) | 100 m |
The farmers carry weights are per hand, not a total. To pull the exact loads for your own division, use the HYROX weight standards tool. The singles divisions are Women, Women Pro, Men, and Men Pro. In short, PRO divisions use heavier loads than Open, and for a runner whose first race is about learning the transitions, Open is almost always right. The comparison sits in our guide to HYROX divisions.
The pace you can hold is not the pace you think
The most expensive mistake a runner makes in a first race, and it is arithmetic rather than fitness. You know your threshold pace, you plan splits from it, and the plan is wrong from the second leg onward, because every 1000 m leg after the first starts on a body whose heart rate and blood lactate ran higher through the station than they did on the run before it. In the Brandt study athletes spent most of the race at what the researchers classed as very hard and hard intensities, defined as ninety to one hundred percent and seventy to ninety percent of maximum heart rate.
One piece of the course rarely makes it into a runner's split math. The ROXZONE is the central transition zone athletes run through between every run and station, and it eats time no runner budgets for. Station order never changes: SkiErg, Sled Push, Sled Pull, Burpee Broad Jump, Rowing, Farmers Carry, Sandbag Lunges, Wall Balls. Knowing what is coming lets you decide in advance which runs are honest and which are damage control, and the effort model for that is in our HYROX pacing guide.
Watch: where running should sit in a HYROX week
Rich Ryan has coached for over a decade and races HYROX at the elite level, and this is the same argument from the other end. Listen for what he says about the placement and intent of running sessions rather than the workouts themselves, because that is the part that changes with your row in the table above.
Five mistakes runners make in a first HYROX block
- Adding running because running is what you know. The trail and high-volume rows fail here. More aerobic volume on a large base is the lowest-return change available.
- Starting at a pace your training justifies. The 5k row fails here. Threshold pace was measured on fresh legs, and you get those once.
- Building a block straight off a marathon. Fitness banks, connective tissue does not.
- Assuming a strong engine covers the loads. The triathlete row fails here, and the one study is direct: nothing measured about the athletes predicted station time.
- Training the stations and never the joins. Going from one to the other is a third skill, and it is the one the race tests.
Frequently asked questions
Is HYROX training good for runners?
It is, with a caveat. In the only published study of a HYROX race, Brandt and colleagues found aerobic fitness correlated most strongly with finishing time, so a running base is a genuine advantage. That study found the correlations held only for the runs and not for the stations, so the advantage stops where the running stops.
What is the best running technique for HYROX?
Technique matters less than the transition. Holding form for the first couple of hundred metres out of a station is the skill the race tests, because only the opening leg is run fresh. Rehearse running into a station and back out rather than drilling stride mechanics in isolation.
What is the 80 percent rule for running?
It is the polarised-training guideline that roughly eighty percent of training volume should sit at easy aerobic intensity, with the remaining fifth genuinely hard. It comes from distance-running literature rather than from HYROX, and it still applies, because the race is eight rounds, each a 1 km run followed by one functional workout station, and the easy volume supports the hard work.
What is the 3-3-3 rule for running?
A beginner structure some coaches use: three runs a week, three weeks of building, then a lighter fourth. It is a general running convention rather than anything specific to HYROX. For a runner who already trains, the useful question is what to change, not how many runs to start with.
How many strength sessions does a runner need for HYROX?
The sources disagree, and it depends on your running frequency. A systematic review of distance runners supports two to three sessions a week as an absolute count. A concurrent-training review, reported inside the HYROX study, frames it as a ratio to your endurance frequency. At low running volume those agree and at high running volume they do not.
Should I lift before or after my run?
A meta-analysis by Eddens and colleagues found lifting before endurance work benefited lower-body dynamic strength, with no effect of sequence on the adaptations they measured over a full programme. The order protects the lift. That review did not test how either order affects the quality of one run on the day, so separate days are the clean answer when running quality is the priority, and running first is the compromise if both must share a session.
Which HYROX station do runners struggle with most?
Usually the sandbag lunges and the farmers carry. The lunges load a knee and hip pattern steady running never trains, and the carry tests grip and upper-back endurance over 200 m. Both land in the back half, when a runner has the least left.
Will HYROX training make me a slower runner?
The evidence points the other way. A systematic review of strength training in distance runners found running economy generally improved by two to eight percent, though not in every study included, and found maximal oxygen uptake and body composition unaffected. Losing running fitness usually comes from cutting running volume, not from lifting.
