An 8-week running plan for HYROX preparation

How many runs per week do you need for HYROX?

Three. A long zone 2 run that builds your base, one quality session of hard running on fresh legs, and a third run that starts easy and turns into race-condition work in week 5. We picked three because each run has a distinct job, and because the running has to fit beside the station training this plan doesn't schedule. Published HYROX running guidance spans 2 to 5 runs a week, and three is where most of the run-focused plans land.

At its peak the plan asks for roughly three hours of running a week, most of it in the long run. If your week genuinely can't hold three runs, keep the long run and the quality session. Those two carry the base and the speed, and the race-condition work returns when your week does.

What running sessions should a HYROX training week include?

A zone 2 long run, one quality session, and, once the race is close, a run that starts straight off station work. Running is the largest single component of a HYROX race, and each session trains a different part of it.

The long run builds the aerobic base. It sits in zone 2, one of the zones a HYROX training plan uses, and it holds the same target as the easy run beside it.

The quality session is hard running on fresh legs: the Norwegian 4x4 in the base weeks, then 1 km repeats at your target average race split once the block turns race-specific.

The compromised run reproduces the race's defining condition, running on legs that just finished station work. It enters in week 5, when the base can absorb it.

Threshold running is a session type this plan doesn't schedule. The quality slot carries the week's hard running, and the long run carries its volume.

What do you run in weeks 1 to 4?

An easy zone 2 run, a Norwegian 4x4, and a long run that grows by 10 minutes a week. These four weeks lay the base that weeks 5 to 7 turn into race stress.

• Easy run: 45 minutes in zone 2.
• Quality: the Norwegian 4x4.
• Long run: 60 minutes in week 1, 70 in week 2, 80 in week 3, 90 in week 4, all in zone 2.

The long run is the only number that moves, and it moves 10 minutes at a time because these weeks only work if the volume gets absorbed. A long run that leaves you limping into the quality session built nothing.

One 4x4 a week is the dose for a mixed week like this one; a dedicated VO2 max block is built differently, and the 4x4 guide programs that case.

Most of these weeks are zone 2 minutes, and RunBeat holds you there by voice:

Zone Training in RunBeat RunBeat tells you to speed up or slow down to stay in zone, right over your music or podcast.

What do you run in weeks 5 to 7?

1 km repeats at your target average race split, the compromised run, and the 90-minute long run. The base is built; these three weeks point it at the race.

• Quality: 1 km repeats at your target average race split, which comes out of your goal time.
• Compromised run: once a week, in the easy run's slot.
• Long run: 90 minutes in zone 2, unchanged from week 4.

Put the two hard sessions at least two days apart, and the long run at the other end of the week from the repeats. Three runs plus your station work is a full week.

Your target average race split comes out of your goal time, and deriving it has its own guide:

What running intervals should you do for HYROX? Six 1 km reps at your target average race split, on fresh legs, with 90 seconds of walking rest between reps.

Which station to use as the compromiser, and what governs the run off it, is its own question:

How do you train compromised running? One station straight into a run, with no rest in between, repeated four to six times.

RunBeat runs the race-pace repeats as its 1 km Repeats preset:

How do you taper the running before a HYROX race?

Cut running volume by about 40% in week 8 and change nothing else. The runs keep their intensity, the week keeps all three, and each one gets shorter.

• Early in the week: the race-pace session at reduced volume, same split.
• Midweek: 30 minutes in zone 2.
• Two or three days out: 20 minutes in zone 2.

The compromised run comes out in race week. The race itself supplies that condition, and rehearsing it days before the start costs recovery the taper exists to bank.

We hold the taper to one week because the plan's race stress lives in weeks 5 to 7, and a second taper week would come out of them.

Published HYROX tapers cut volume by 20 to 50% over the final week or two. The controlled evidence lands in the same place, in a 2023 meta-analysis covering 174 endurance athletes. Tapers of up to 21 days that progressively cut volume by 41 to 60%, with intensity and frequency unchanged, improved time-trial performance.

Can you train for HYROX running entirely on a treadmill?

Yes for the heart-rate-governed sessions; the race-pace session is the one to take outside. The zone 2 runs and the 4x4 are governed by heart rate, and treadmill heart rate stays within a few BPM of outdoor running at the same easy or moderate speed. On those sessions the belt changes nothing the plan cares about.

The 1 km repeats are governed by pace, and pace is what a treadmill reports worst. The belt's display, your watch, and your own sense of effort routinely disagree, and none of them measures you. Run the repeats overground where you can. Where a treadmill is the only option, set the belt from your split.

A HYROX race is an indoor event, but not a treadmill-like one. Coaches who train HYROX athletes say outside is better, and that consistent belt running is still worth doing as long as it isn't exclusive. Races involve weaving, reacceleration, and variance between venues that a belt never rehearses.

To put numbers on the zone targets, the HR zone calculator runs both methods side by side.
