What happens before you arrive and at check-in
Settle the admin before you travel. Your start time appears on the event page's start list about three days before the race. Singles and Doubles racers get a technical briefing video, which HYROX US says goes up on the Monday before and is mandatory; Relay teams send one person to a briefing on site. The event page also gives the number of laps in each run at your venue. You will need it.
| When | What happens | Who says so |
|---|---|---|
| Race week | Watch the briefing video; check the laps per run on the event page | HYROX UK and US FAQs |
| About 3 days before | Your start time appears on the start list | HYROX UK FAQ |
| 90 min before your start | Arrive and check in | HYROX UK FAQ |

| 10 min before | Be at the start tunnel for instructions | Singles rulebook 11.4 |
At check-in, show government-issued photo ID and your registration confirmation (HYROX UK asks for the ticket QR code or barcode). You get three things:
- A timing chip on an ankle strap. It stays on an ankle for the whole race; race without it there and your result reads Did Not Start. Hand it back afterwards, as HYROX UK charges for a lost chip.
- A race number, which shows your start time and place in the wave: 080030 means an 08:00 start, at the tunnel by 07:50.
- A wristband, white, grey, black and/or green by division. Wear it where judges can see it: it marks your division and wave, and HYROX UK says judges use it to assign your weights.
Your start time must also be clearly visible on your arm, and starting in another wave without the organisers' approval is a disqualification. Until you start, stay off the run course and out of the Roxzone, where you enter and leave the stations: crossing it early can trigger your chip and give you a wrong time.
Bag drop takes one cabin-size bag, and once it is in you cannot keep going back to it. Packing is on what to wear and pack and the days before on how to taper. If you arrive hours early to watch friends, sit down between their waves: HYROX UK's advice is to reach the start fresh. First race? Start with the beginners guide and how a HYROX works.
How to warm up in the warm-up area
Every venue has a warm-up area with race equipment, for racers only. Treat it as preparation, not a workout. A review of warm-up research in Sports Medicine found that an active warm-up tends to improve efforts of five minutes or more when you start relatively fresh with your oxygen uptake already raised, that a short burst of the task itself has been reported to add to it for some tasks, and that a warm-up that overheats you can hurt endurance performance. A later review by McGowan and colleagues adds the gap between warm-up and start, which research has often overlooked: keep your temperature up through it.
A 15 to 20 minute warm-up
- 5 to 6 minutes easy. Jog, or use a free rower or SkiErg, at a pace you could talk at.
- 5 minutes of mobility on the move. Leg swings forwards and sideways, 10 per leg; 10 walking lunges; 5 inchworms; hip and arm circles.
- 5 minutes of race primers. Three strides of 15 to 20 seconds building to your run 1 pace; 10 squats or wall balls; a few burpee broad jumps if there is room; 20 to 30 seconds on a free erg at race effort.
- 2 to 3 minutes walking to the tunnel, with a few sips of water.
Start about 35 minutes before your start time to finish 15 minutes out. You should feel warm and a little out of breath, not tired. Your bag is already dropped and you stand in the tunnel for ten minutes, so keep moving there: leg swings, squats, small bounces. On a first race, shorten the primers but keep the strides: they set your sense of race pace before the first kilometre.
The start tunnel, and why to hold back on the first run
Ten minutes before your start you assemble at the start tunnel for the instructions. When your wave goes, go with it: waiting in the tunnel after it starts can cost 1 minute.
Then comes the mistake HYROX itself warns about. HYROX UK says it sees people run a personal best in the first kilometre and push hard through the SkiErg over and over again, carried by the music and the crowd. It compares the race with a half marathon or an Olympic-distance triathlon: pace yourself and find your rhythm.
A study of 24 Pro men at HYROX Madrid 2025 shows the fade. Their running speed declined run by run, from 16.1 km/h on run 1, close to the 16.4 km/h of their second ventilatory threshold measured in the lab beforehand, to 13.6 km/h on run 8. Across the runs and the Roxzone they averaged about 84% of that threshold speed, and the authors concluded that sustaining a higher intensity appears central to a shorter running time. Twenty-four trained men in one race is a small sample, but it matches what HYROX describes, and a pacing review in Sports Medicine reports that in events longer than about two minutes, performance times may improve when pace is spread more evenly. The stations make an even pace impossible in HYROX, so the practical version is even effort.
Run the first kilometre at the effort you could hold for all eight runs. Fresh legs and a loud venue make it feel too easy. That is correct.
Run 1 has no station before it, so even at that effort it will usually be your quickest run. If runs 2 and 3 already felt like a fight to hold, you started too fast.
Ski at a pace you could hold for twice the distance. Both sleds and the burpee broad jumps come next, and they are where an early surge gets paid back.
How to pace the eight runs
Aim for even effort, not even pace. Your pace will drift as the stations add up; what you control is how much. Settle on runs 2 and 3, hold that effort through run 7, then spend what is left on run 8 and the wall balls. The first minutes off each station feel worst, and training that switch is on compromised running.
Do not judge run 8 against the others. On HYROX results pages it runs from your last Roxzone exit to the wall balls, so the last stretch through the Roxzone is counted as running and can read slower without you slowing down.
Count your own laps
Laps per run depend on the venue, and counting them is your job. Lap screens are only an aid, and an extra lap earns no time back. A missing lap costs 3 minutes on a four-lap course, 5 on three laps and 7 on two; on a one-lap course, or for a whole missed run, it is a disqualification.
- Learn your venue's lap count from the event page and study the athlete map.
- Count each pass of the lap point with the run number: run 3, lap 2. Use your fingers when your head stops working.
- Unsure while still on the course? Run one more lap. An extra lap costs a lap's time; a missing one costs minutes.
- At 4:00 per km or faster you must use the inside Fast Lane; everyone else stays in the outer Running Lane.
Racing Doubles? You run every kilometre together, and one partner running ahead costs 1 minute, so the slower runner sets the pace. More in how doubles works.
What to do at each station
Technique for each station is on its own page, starting from the eight stations. On race day, these are the points that cost or save time.
1. SkiErg
The damper is preset to 6 and you may change it. Keep both feet on the base, heels off the floor, and at 1,000 m raise an arm and wait for the judge before you step off. Ease off over the last 100 m so your breathing settles before run 2. More on the SkiErg and the row.
2. Sled push
Use the lane the judge assigns. The whole sled must cross the line at the end of each 12.5 m length before you turn it. Stay low with short, quick steps. A sled is hardest to move from a standstill, so if you must stop, stop at the end of a length, not halfway. More on the sleds.
3. Sled pull
Pull standing, from inside the box at your end of the lane, without stepping on its lines while you hold the rope, and keep the rope in your lane. Event chalk is allowed here. Lean back and drive with your legs as you pull hand over hand, rather than with your arms alone.
4. Burpee broad jumps
Chest to the ground on every burpee; jump and land with both feet together, hands no more than 30 cm in front of your front foot, no extra steps. You may step out of the bottom. After one warning, each fault costs 15 seconds. A moderate jump you can repeat beats long jumps you need to recover from. More on burpee broad jumps.
5. Rowing
Set the footplate before you start; the damper is preset to 6. You may stop and rest, but you stay seated until the judge confirms 1,000 m. Row long, steady strokes with a loose grip: the farmers carry follows the next run.
6. Farmers carry
Pick up your colour: white, grey or black. The wrong kettlebells for any part of the 200 m means repeating the station or disqualification. You may set them down if they do not move forward; do it before your grip goes, not when it does. Return them upright to the box, or take 30 seconds unless you fix it before leaving the Roxzone. More on the farmers carry.
7. Sandbag lunges
Check the colour of the bag too. Back knee clearly down on every lunge, stand tall, alternate legs, no shuffles; you may pause standing with your feet parallel. The bag stays on your shoulders: putting it down costs 15 seconds each time. A steady rhythm with short pauses beats a fast start and long stops. More on sandbag lunges.
8. Wall balls
100 reps, to 2.70 m for women and 3.00 m for men. Start standing with the ball in both hands, squat below parallel and hit your target. There are no warnings: rep or no-rep. You may take your shoes off at your target, then carry them to the finish. Decide your sets before you start, end each set before your legs force you to, and keep the rests between them short. More on wall balls.
How to move between runs and stations
Between the run course and the stations is the Roxzone, entered through IN arches and left through OUT arches. The wrong arch costs 2 minutes each time, as does leaving a station by its IN arch, and the timing system catches many of these from chip reads. Know which arch you need before you reach it.
On HYROX results pages, Roxzone Time adds up the time from each Roxzone entry to the first seven stations and from each of those stations back out; the way to the wall balls is left inside run 8. Layouts differ from venue to venue, one reason splits from different venues do not compare. What counts as a good time is on finish times.
- Water is there at least once before, during or after each pass through the Roxzone, sometimes with a sports drink. It is for drinking only: pouring it over yourself costs 2 minutes, and a cup dropped anywhere but a bin can too.
- Nutrition you want during the race must be on you from the start. A drink or food from anyone but the aid stations, spectators included, is outside assistance: 2 minutes each time.
- Chalk: event chalk only, only at the sled pull and the farmers carry, never carried elsewhere. Anything else costs 2 minutes.
- Lanes and kit: use the lane, equipment or wall-ball station the crew assign you, or take 2 minutes.
Walk if you need a few breaths, drink as you pass, and keep moving. Standing still is where minutes go unnoticed.
The mistakes that cost first-timers minutes
Rule mistakes are the ones with a fixed price, and the rulebook sets each one. The full list is on rules and penalties.
| Mistake | What it costs | Rulebook |
|---|---|---|
| Losing count of your laps | 3 to 7 minutes per missed lap by lap set-up; disqualification on a one-lap course | 12.1.1, code 01 |
| Wrong kettlebells or sandbag | Repeat the whole station at the right weight, or disqualification | 8.6, 8.7, code 13 |
| Wrong Roxzone arch, or leaving a station by its IN arch | 2 minutes each time | 12.1.4, codes 04 and 05 |
| Starting in the wrong wave without approval | Disqualification | 7, code 19 |
| Waiting in the start tunnel after your wave goes | Can be 1 minute | 7, code 16 |
| Timing chip not on an ankle | Did Not Start | 7, code 20 |
| Leaving the SkiErg, rower or wall balls short | Disqualification, incomplete station | Codes 06 to 08 |
| Pouring water over yourself, or a cup on the floor | 2 minutes each time for pouring; a dropped cup can cost 2 minutes | 7.1, 10.4, code 22 |
The rest cost time without any penalty:
- Starting too fast: the personal-best first kilometre and hard SkiErg that HYROX UK keeps seeing.
- A warm-up that tires you, or one that ends half an hour before your start.
- Racing the person beside you. Staggered starts make your place in a wave hard to track, as HYROX says, so they may be on a different run.
- New kit on the day. Settle shoes, gloves and belt in training; what is allowed is on kit.
What to do when something goes wrong
A warning or a no-rep
At stations 1 to 7 you get one warning per station; from the second fault the rep does not count and a time penalty applies, and each further fault adds another. At the wall balls there are no warnings. After a call, slow down and make the standard obvious for a few reps: chest flat, knee down, hips below knees. Do not argue: the rulebook treats excessive disputes as poor sportsmanship.
A missed lap or a station out of order
Lost count on the run course? Run the extra lap. Missed a station? You may complete it before you enter the wall balls; the first station out of order costs 3 minutes and a second is a disqualification, as is missing a whole station or run or leaving one unfinished.
Cramp
A review in the Journal of Athletic Training recommends gentle static stretching of the cramping muscle until it eases. Do it within the rules: on the rower you stay seated, on the farmers carry the bells may go down if they do not move forward, and on the lunges putting the bag down costs 15 seconds, still cheaper than a station you cannot finish.
Intensity matters here too. In a study of 210 Ironman triathletes, the 43 who cramped had faster predicted and actual race times and more often a history of cramp, with no difference in blood electrolytes or body-weight change. The authors linked cramp to racing at a high intensity, not to dehydration.
Feeling unwell
You can pull out at any point, and HYROX UK says staff along the course and at the stations can call medics. If you feel faint, dizzy or have chest pain, stop and tell the nearest crew member. HYROX's FAQ says there is no time limit, so walking is always an option.
What happens after the finish line
Carry your shoes if you took them off: you cannot go back to the wall-ball area. Hand back your chip. Results go up at results.hyrox.com straight after the event, but penalties and amendments can follow for up to 48 hours, and results pages carry a dispute form.
Compare your runs with each other, not with someone at another venue. If runs 2 and 3 felt like a fight to hold, start slower next time; a run that collapses after one station says what to train. More on getting faster, and the first days after on recovering from a HYROX.
Your event archives itself the day after and moves to PAST. Open it and add your finish time.
The race day itself, opened from your plan, gets a Share chip once it is marked done. It makes a picture of the race to post or send. More in Races and events.
