Pacing strategy for a HYROX® race

How should I pace a fitness race?

Pace the race as eight runs and eight stations, not as one long effort. Plan each run before race day, start under control, keep a steady effort through the middle and spend what is left on the last run and the wall balls. Our recommendation below is built on published data and one lab study.

1. Set a realistic goal time. The good finish time guide shows typical times by level.
2. Put the goal into the calculator and write the eight run splits where you can see them.
3. Run run 1 no more than about 3 to 5 percent quicker than your average run kilometre.
4. Hold an effort of 6 to 7 out of 10 through the middle of the race, using heart rate only as a ceiling.
5. Spend what you have left on run 8 and the wall balls.

What pace should I run the first kilometre?

Run the first kilometre only slightly quicker than your average run kilometre, and slower than it feels. For a 1:30 goal in our calculator the average run kilometre is 5:24, and run 1 is 5:07 to 5:14 on the safe start and even profiles. Adrenaline and the crowd push most athletes out faster than that.

These averages come from the RoxPace results database (guide updated 4 October 2026), which counts more than 280,000 first-time finishers. The two groups are different people, the sample behind the fade figures is not stated, and the source is a commercial site. Even so, the pattern is clear: everyone slows, and first-timers slow more. The same guide advises running run 1 about 15 to 20 seconds per km slower than feels right.

• Take the run 1 target from the calculator, not from how you feel at the start line.
• Settle your breathing in the first 200 m, then hold the target pace.
• If run 1 is faster than the target by more than 10 seconds per km, slow down before the first station.

Which pacing profile should I choose in the calculator?

The calculator has three pacing profiles, and each one spreads the same total running time over the eight runs. Even keeps the runs close together. Realistic is how most athletes actually race: a quick run 1 and a slow run 8. Safe start holds the first runs back. Choose safe start for a first race.

Every profile ends on your goal time, so a quicker run 1 only moves time from the later runs: the realistic profile gains 16 seconds on run 1 over the even one and gives back 19 seconds on run 8. The profiles are our model and not measured data. They show the trade, and your own simulations should set the final numbers.

• Safe start: our recommendation for a first race or when you are unsure of your running fitness after stations.
• Even: for athletes who have raced before and want to hold the splits closest together.
• Realistic: use it to see what going out fast costs you on the last runs, not as a target.

What heart rate should I hold in a fitness race?

Use heart rate as a ceiling for the first two runs and as a warning light after that, not as a target. In a 2025 lab study, athletes spent a median 79.5 percent of a simulated race at 90 to 100 percent of their maximum, so a low cap cannot be held for the whole race.

In the same study the average heart rate was a median 169 bpm over the runs and 174 bpm over the stations, and the wall balls produced the highest heart rate, blood lactate and effort rating. Eleven recreational athletes took part, alone, on a treadmill, so treat the figures as a picture of the shape and not as targets. Use a maximum you have measured in a hard effort, not an age formula, and test your sensor in a simulation first. If it drops out during stations, trust RPE.

What effort should each station feel like?

Use a scale of 1 to 10, where 6 means you can say a short sentence and 8 means a few words. Most of the race sits at 6 to 7, the sleds and lunges at 7 to 8 and the wall balls at 8 to 9. In the 2025 lab study, stations rated harder than runs.

On the 6 to 20 Borg scale, the lab athletes rated runs 13.4 on average and stations 14.4, with a peak of 18 at the wall balls. The Borg scale is not our 1 to 10 scale, so only compare the order: stations feel harder than runs and the wall balls are the hardest part. Read the stations and weights guide for the order and the loads.

Should I run an even split or a negative split?

Aim for an even effort, which in a fitness race gives running splits that slow a little. A true negative split, with a faster second half, is realistic only if you hold back early. Research on pacing finds that prolonged efforts may be faster when effort is spread evenly, and that is the sensible default here.

A review of pacing by Abbiss and Laursen describes six patterns and finds that prolonged efforts of more than 2 minutes may be faster when effort is spread evenly. A fitness race is not a steady effort, because every station changes the load, so match the effort and let the pace move. For the half-way check, compare your time at the end of the burpee broad jumps with half of your goal.

How do I practise pacing before race day?

Rehearse your numbers in a half simulation and in compromised runs, and change them with what you learn. Pacing is a skill you can practise. Our recommendation is to do your last large rehearsal about two weeks before the race.

1. Print the calculator splits for your goal and your profile, and keep them in the notebook or phone you train with.
2. Do a half simulation of four runs and four stations at your run 1 to run 4 targets, as in the 12-week plan, and note your effort and heart rate.
3. Practise the first 200 m after the sled push and the lunges in compromised runs.
4. Adjust the targets: if run 4 felt like 8 out of 10, lower the pace target or choose the safe start profile.
5. Write the three rules you will follow on race day: run 1 target, the heart-rate ceiling for runs 1 and 2, and the effort for the middle.
