- Aim for even pacing: similar run splits from the first kilometre to the last.
- Start the first run and SkiErg deliberately slower than feels necessary.
- Pace by effort first, then use heart rate and splits to check yourself.
- Treat the SkiErg and row as steady stations and save your legs for the end.
- Plan your wall ball and lunge approach before race day, not during it.
Why pacing decides HYROX results
HYROX is a long event. Most people are racing for well over an hour, which means it is overwhelmingly aerobic. In any long aerobic event, the fastest way to cover the distance is to spread your effort evenly. Surges and fast starts cost more than they save.
HYROX has a twist that makes this even more important: the hardest stations for most people come last. Sandbag lunges and wall balls land on your legs at the point where they are most fatigued. If you have spent your energy early, the final two stations and the final run can take far longer than they should.
The classic first race looks like this: a fast first kilometre fuelled by adrenaline, a hard SkiErg, a brutal sled push, then a slow fade for the rest of the race. The fix is simple to say and hard to do: go out slower than you want to.
Setting your run pace
Your HYROX run pace will be slower than your stand-alone 10k pace, because every run comes after a station and your legs are carrying fatigue. For most people, a sensible target for the early runs is noticeably slower than their fresh 10k pace, with the aim of holding that pace, or close to it, all the way through.
The best way to find your number is from training. Run 1 km repeats after station work in your HYROX simulation workouts and note the pace you can hold for all of them without the last ones falling apart. That pace is your starting target for race day.
Judge success by consistency. If your first run was a lot faster than your fifth, you started too hard. A well-paced race often has the first run as one of the slower ones, because you are deliberately holding back.
Pacing by effort, heart rate and splits
Use three tools together, in this order of priority:
- Effort. On a scale of 1 to 10, the first two runs should feel like about a 6 or 7, comfortably hard but controlled. Allow it to rise to 8 in the middle and push to 9 only in the last run and wall balls. The guide to RPE and RIR explains effort scales in more detail.
- Heart rate. If you know your threshold heart rate, keep the first half of the race at or a little below it. Heart rate lags behind effort and drifts upward as the race goes on, so treat it as a ceiling rather than a target.
- Splits. Check your run times after each kilometre. If one is much faster than planned, ease off on the next rather than banking time.
Heart rate is the most useful early warning. If it is already near your maximum on run two, you are paying for it later. More on this in heart rate training for HYROX.
Pacing each station
- SkiErg: a few seconds per 500 m slower than your best fresh 1,000 m. This is not the place to win.
- Sled push and pull: steady and continuous. Avoid stopping, but do not sprint the first length.
- Burpee broad jumps: a rhythm you could hold for twice the distance. Moderate jumps.
- Rowing: controlled pace, bring your breathing down while still moving well.
- Farmers carry: brisk walk, as few planned set-downs as you can manage.
- Sandbag lunges: slow and continuous from the first step. No early sprint.
- Wall balls: your planned sets and your planned rests, counted in breaths.
The second half: holding on and finishing strong
If you paced the first half well, you will reach run five feeling tired but in control. This is where the race really starts. Your job now is to keep your run pace close to where it was, keep moving through the Roxzone and give the final stations everything you saved.
Expect runs six and seven to feel hard even if you paced perfectly. That is normal. Focus on form: shorter strides, quicker steps, relaxed shoulders. Break the run into laps and each lap into halves. The transitions matter too; see the Roxzone guide for how to keep them tight when you are tired.
The last run, after the lunges, is where your pacing is tested most. If you have anything left, use it on the wall balls rather than the run into them. Rushing into the final station with nothing left in your legs usually means more no-reps and longer rests.
If things have gone wrong and you did start too fast, do not panic. Accept that the plan has changed, slow your runs by a small amount, walk briskly through the Roxzone and focus on moving continuously on the stations. Damage limitation is a skill too, and plenty of people rescue a decent finish from a poor start by staying calm.
Practising your pacing
Pacing is a skill you build over weeks, not something you decide on the start line. Every hard session is a chance to practise it. Use your training runs, intervals and simulations to learn what each effort level feels like on tired legs, and practise holding back at the start of sessions even when you feel fresh.
A useful test is a set of four 1 km runs with a station between each, where your only goal is to make the fourth run the fastest. Most people find this surprisingly hard the first time, and very revealing about how they naturally pace.
Structured, race-specific sessions help. Lycan Strength runs Engine classes on Monday, Wednesday and Friday and Lycan Shred on Friday evening, all good places to rehearse pacing with other people pushing alongside you. For realistic expectations about the clock, read how long does HYROX take.

Questions
How fast should I run in HYROX?
Slower than your fresh 10k pace for most people, at a pace you can hold for all eight runs. Find it by running 1 km repeats after station work in training.
Is it better to go hard early in HYROX?
No. The hardest stations come at the end, so a fast start usually leads to a much bigger slowdown later. Even pacing is faster for almost everyone.
Should I pace HYROX by heart rate?
Use effort first and heart rate as a ceiling, especially in the first half. Heart rate drifts up as the race goes on, so it is best used as an early warning that you are going too hard.
