What running intervals should you do for HYROX?

What pace should you run HYROX intervals at?

Your target average race split, at it and never faster. Even pacing is the skill a HYROX race rewards, and reps at the average are how that skill gets built.

The field, on average, does the opposite: athletes give up about 1:30 per kilometer between the first run and the last. Holding one split for eight runs is the unusual, trainable thing, and these reps are how you train it.

Published km-rep sessions for HYROX run at race pace, and faster running is saved for the shorter VO2 max reps.

None of these reps carries a heart rate target. In HYROX run training, heart rate is read as a comparator across sessions.

How do you work out your HYROX run pace from a goal time?

Subtract your station and transition time from your goal finish time. What's left is your run budget. Spread it over the race's 8 km of running and you have your target average run split, the pace every rep runs at.

A pace chart has to guess at your station time before it can say anything about your running. Your last race measured it, so the method asks for the measurement instead.

Worked through: a 90-minute goal, with 48 minutes of stations and transitions in your last race, leaves a 42-minute run budget. Over 8 km that is 5:15 per kilometer, so the reps run at 5:15. Six of them, with the walking rests and the warm-up and cool-down, come to just under an hour. The numbers are one athlete's and nobody's in particular; put your own through the same arithmetic.

On a treadmill, the same split converts to a belt speed, and the display showing it is one of three instruments that disagree about your pace.

How many reps should you do, and why six and not eight?

Six. New to interval work, start at four and add one rep a week. Published counts for this session sit between five and eight, with six the most common; starting at four is our on-ramp for a first-time interval runner.

The rep is a kilometer because that is the race's run segment: eight runs of roughly 1,000 m each, one before every station. Every source that explains its rep distance points at that structure.

Some coaches run the same target pace over 400 m and 800 m reps, and RMR Training programs threshold time blocks instead of km repeats.

We stop at six because 6 km of race-pace running on short rest is a full quality day. The race's other two runs start at a station's exit, on legs that aren't fresh, and you train them separately.

How much rest between 1 km reps?

90 seconds, and you walk it. Published rest for this session spans 60 seconds to 2 minutes.

That span comes with a single stated reason: transitions in a HYROX race are brief, so the rest between reps stays shorter than track-session rest.

Our 90 seconds buys two things at once: rep six still lands on the target split, and the six reps stay one session instead of six separate efforts.

The walk is ours as well: with the rep pace as this session's only target, the recovery doesn't need one of its own.

Should running intervals be done fresh or after station work?

Fresh, for this session, and fresh is only half the picture. Published HYROX preparation carries race-pace running in two concurrent streams: interval days on fresh legs, and sessions where the run begins the moment a station ends. These reps are the first stream. Running straight off a station is a different session. Here's how to train it:

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

The station-first stream builds toward race day: general running fatigue is its load early in a block, race-specific interference later on. One published week-by-week plan keeps fresh km reps at HYROX pace in its final weeks, beside the compromised sessions. The fresh reps stay a late-block tool, and the compromised work never replaces them.

Fresh days also survive the whole build. Every source that sketches a complete training week holds standalone running-quality days in it, and two warn outright against going compromised-only.

Sharing a week between the two is a bigger call than any one session. Here's the full week:

What pace should you train at for your first HYROX?

Your 10k pace plus 20 to 30 seconds per kilometer, held as a provisional target for the first block. The goal-time method has nothing to run on yet: with no race behind you, the goal is invented and the station time is missing. Current running fitness is the one real number available, so the target is built from it.

HYROX coaches put race run pace well below 5k pace, near half-marathon effort, and one rejects the 5k anchor outright.

We anchored on 10k pace: the real, recent number a runner most likely owns. The 20 to 30 seconds is sized to land the target in the effort region the coaches describe. Published versions of the rule differ in anchor and offset alike; the nearest, on RunReps, reaches the same construction and calls it a starting point.

One finished race replaces all of it. You come away with an earned goal and a measured station time, the derivation runs, and the derived split becomes the target. For the debut itself, race a pace rather than a finish time; first-race coaching repeats nothing more often.
