Most Hyrox plans tell you what to do on Tuesday. Almost none tell you whether any of it is working. A Hyrox simulation workout is how you find out: a single session that reproduces the race's defining stress, running under fatigue and stations at a running heart rate, closely enough to give you a number you can act on, without costing you the two-week recovery of a real race.
The classic first-timer mistake is treating the simulation as a time trial. It isn't one. Run it flat out and you learn exactly one thing: your current finish time. Run it as a test, with planned pacing and recorded splits, and you learn the four things that actually change your training: which station spikes your heart rate, where your running pace collapses, how much time you leak in transitions, and whether your engine or your strength is the limiter.
- A simulation is a diagnostic, not a performance. Run it at goal pace, not all-out.
- Two full ones per block (6 and 3 weeks out), never inside the final 10 days. Half simulations in between.
- With no sled or spec gym, substitute the stimulus (duration + energy system), not the movement. The session still works.
- Four numbers matter: run drift, most costly station, transition %, and engine-versus-strength ratio.
What a Hyrox simulation workout is (and what it isn't)
Direct answer: it's a controlled rehearsal, full or half distance, of the 8-run + 8-station format, run at planned pace with splits recorded, used as a diagnostic rather than a performance.
It gets confused with three other things. A time trial first: same session, run flat out, producing only a finish time. A "Hyrox-style" metcon second: a circuit that borrows the movements but breaks the run/station alternation, removing exactly the stress you're trying to measure. And a station skill day third: useful for technique, but with no running between blocks it says nothing about compromised work.
A true simulation has a real cost: 3 to 4 days of recovery, more in a first build. That's why it belongs at 6 and 3 weeks out, not weekly. A session that costs three days is only justified if you extract a training decision from it.
When to run one, and the half-simulation alternative
| Weeks to race | Recommended session | Recovery cost |
|---|---|---|
| 10 to 8 | Half simulation | ~1 day |
| 6 | Full simulation | 3-4 days |
| 5 to 4 | Half simulation | ~1 day |
| 3 | Full simulation | 3-4 days |
| 2 to 0 | None (taper) | - |
A half simulation is 4 × 1km runs alternated with 4 stations, keeping the official relative order. It costs roughly one day of recovery and repeats every two weeks. It's the option to favour for an athlete in a first build, or anyone already carrying a high weekly load: you get run drift and per-station cost, which is most of the signal, without the three-day hole.
To place these sessions inside a full block, the 12-week Hyrox training plan shows where they fall across the Base, Build, Sharpen and Taper phases.
The session, station by station
The official format, in order: a 1km run before each station, eight times. Ski erg 1000m, sled push 50m, sled pull 50m, burpee broad jumps 80m, rowing 1000m, farmer's carry 200m, sandbag lunges 100m, wall balls (75 men / 100 women in Open). No added pause between blocks: the transition is part of the session and must be timed.
The real blocker, for most athletes, is equipment. Here are the substitutions that preserve the stimulus, duration and energy system, rather than the movement.
| Station | Substitute | Target |
|---|---|---|
| Ski erg 1000 m | Continuous burpees | 4-5 min |
| Sled push 50 m | Heavy farmer's carry 100m or loaded hill | 2-3 min |
| Sled pull 50 m | Continuous band rows | 3-4 min |
| Burpee broad jumps 80 m | Same, no equipment needed | 4-6 min |
| Rowing 1000m | Assault bike or fast 1km run | 4-5 min |
| Farmer's carry 200 m | Heavy dumbbells or kettlebells | 2-3 min |
| Sandbag lunges 100 m | Back-rack barbell lunges or weight vest | 4-6 min |
| Wall balls 75/100 | Light thrusters | 4-7 min |
Pacing targets by goal finish time
Counter-intuitive but central rule: the simulation is paced off your goal time, not your current fitness. The whole point is to find where the target pace breaks. Run it at your comfortable pace and you learn nothing you didn't already know.
| Goal finish | Run pace / km | Avg station time | Max transition |
|---|---|---|---|
| Sub-60 min | 4:00-4:20 | ~3:00 | 20 s |
| 60-75 min | 4:30-5:00 | ~3:45 | 25 s |
| 75-90 min | 5:15-5:45 | ~4:30 | 30 s |
| 90+ min | 6:00-7:00 | ~5:30 | 40 s |

The splits to record (and the four numbers that matter)
Record four things per block: run time, station time, transition time, and an RPE per segment. Then derive four indicators.
1. Run drift. Compare run 8 against run 1. A 5 to 8% slowdown is normal and expected, that's the compromise effect. Beyond 8%, your aerobic engine is the limiter.
2. The most costly station. Look at which station is followed by the slowest run relative to your average. It's rarely the station that felt hardest in the moment, it's often the sled push or the sandbag lunges.
3. Transition percentage. Add up your transition times and divide by total time. Above 6%, that's free time on the table: transitions are trainable and cost no fitness at all.
4. Engine or strength. Compare your run RPEs against your station RPEs. If the runs consistently cost you 2 more points, your engine is the limiter. If it's the stations, it's strength endurance.
Log all of it as ONE session with splits, never as sixteen entries. Our Hyrox training load method explains why sixteen entries break the maths.
Decision table: what each result tells you to change
| Result | Limiter | Next-block change |
|---|---|---|
| Run drift > 8% | Aerobic base | +20% easy zone 2 volume |
| One station tanks the next run | Station strength endurance | 2 weekly blocks on that station |
| Transitions > 6% of total | Exit technique | Rehearse station exits |
| RPE capped but pace falling | Pacing discipline | Run to the watch, not to feel |
Closing
A well-run Hyrox simulation doesn't give you a finish time, it gives you a shopping list. Run it at goal pace, record your splits, compute your four numbers, and you'll know exactly what to change in the six weeks that remain. That's the difference between training hard and training informed.
If you don't have a structured block yet, start with the 12-week plan, and if this is a first race, the beginner's guide lays the foundations before you attempt a simulation. On the day, the race day checklist heads off the mistakes that quietly cost minutes.
