HYROX Simulation in Seattle: What a Sim Day Is and How to Use One
A HYROX simulation is the full race format, stations in order at race spec with the running between them. Here is what a sim is for, how to fit one into a race build, how to read your result, and three ways to do one in Seattle.
If you have searched for a HYROX simulation in Seattle, you probably already know what a HYROX race is and want somewhere to practice the whole thing before race day. That is a sensible thing to want. This post explains what a sim is, why it earns a place in a race build, how often to do one, how to read your result, and the three ways you can do a HYROX sim with us in Belltown.
What a HYROX simulation is
A simulation is the race format, done on purpose, in one session. You do all eight stations in race order, at race spec, with a 1 km run between them. The order is the one our stations post walks through:
- SkiErg, 1,000 m
- Sled push, 50 m
- Sled pull, 50 m
- Burpee broad jump, 80 m
- Row, 1,000 m
- Farmers carry, 200 m
- Sandbag lunges, 100 m
- Wall balls, 100 reps or 75 reps
The running is not filler. Eight kilometers of running is half of what you are practicing, and it happens on legs that have just pushed a sled or thrown a burpee. A sim is the only kind of session where all of that arrives in the right order.
A sim is also not a fitness test. It is a rehearsal, and you can scale it. A sim done at a pace you can hold teaches you far more than one where you blew up on the second run and walked the rest.
Why rehearsing the format matters
You can train every station well on its own and still have a hard first race. The stations are rarely the problem. The joins between them are. Three things only show up when the pieces are linked.
Transitions. Coming off a run and walking straight into a sled push feels different from starting a sled push fresh. Your breathing is up, your legs are warm but loaded, and you have a few seconds to decide how hard to go. Done once, this feels awkward. Done a few times across a build, it becomes routine.
Pacing. A single station at a steady effort tells you very little about how to spread effort across a whole race. A sim shows you what the first kilometer should feel like, and what it costs you if you run it too fast. Our pacing strategy post goes into the detail, and a sim is where you find out whether you can follow it.
Compromised running. The run after the sled and the run after the burpee broad jump are not the run you do on a treadmill on a Tuesday. Your legs are doing the same job with less to give. This is the hardest thing to approximate with separate workouts, because it depends on what came just before.
There is a quieter benefit too. Once you have done the whole format, the race stops being an unknown. You know roughly where it will hurt, and you can plan for it.
How to use a sim in a race build
Think of a sim as a checkpoint, not as the training itself. Most of your weeks go to the stations in smaller pieces, to running, and to the strength and aerobic base that supports both. Our 12-week prep plan lays that out. It places a partial sim in week 8 and a full sim in week 9, inside the race-prep block.
Here is how we think about timing.
Earlier in the build, do a partial sim. Link a few stations with the runs between them. This is where you find out which transitions are awkward and which station you have been quietly avoiding.
In the final block, do a full one. Once the stations are comfortable, a full sim shows you the whole race rhythm. Leave enough time afterwards to recover before the race, because a full sim is a hard day and you do not want to arrive at the start line still carrying it.
Do not do many. A sim is demanding, so it does not need to be weekly. A small number, spaced out, with ordinary training in between, does more than stacking them. If you are not sure where one fits in your week, ask a coach and we will help you place it.
If your race is close, the race-day checklist covers the morning-of routine. A sim is a good chance to rehearse that as well: eat what you plan to eat, wear what you plan to wear, and see how it all behaves.
How to read your result
The total time is the least useful number from a sim, and it is the one everyone looks at first. Here is what we would look at instead.
Compare your runs. Put your first kilometer next to your last. If the first was far quicker, you started too hot and the later runs paid for it. If they are close, you paced well. If the last was faster, you probably had more in you.
Find the station that cost you the most. Not the one that felt worst, but the one where you lost the most time against what you expected. That is where your next few weeks of station work should go.
Notice what happened at the wall balls. They come last, so they show you what was left. If your reps broke up early, the earlier stations or the runs took more than you planned for.
Check the transitions. Did you stand around before a station? Did you set the sled up badly? Time lost in setup is the easiest time to get back.
Write it down while it is fresh. A line or two about how each run felt, and which station surprised you, is worth more than the splits on their own.
A good sim leaves you with one or two clear things to work on. That is all it needs to do.
HYROX training in Seattle: three ways to do a sim at Persistence Athletics
We train HYROX at 3025 1st Ave in Belltown, and there are three ways to get a simulation done here. They suit different people.
The two coached HYROX classes
Our HYROX classes run on Wednesday from 5:00 to 6:30 PM and Saturday from 9:30 to 11:00 AM. Both are 90 minutes and both are coached by Jacque. They are station-by-station sessions with running blocks and pacing work, and we run full station-by-station simulations at race spec, so the format is familiar before you toe the line.
This is the place to start if the stations are new to you. A coach is there to set your sled position and call your wall ball target, and the class scales, so runners, CrossFitters and first-timers train side by side. The classes are included with membership, and you can drop in for $35. Your first class is free. Details are on the HYROX Seattle page.
The sim event
We also run sim events, which are the closest thing we offer to a race morning. The most recent was a half-distance sim at the end of October: every station at half the distance, run in heats, with scaling allowed at every station. It was designed as a first race you can actually finish. An event like this gives you a start time, other people in the lanes around you, and a heat to prepare for, which is hard to get from training alone.
Dates and prices for the next one are posted on the HYROX Seattle page, so check there rather than relying on what we ran last time.
The private sim rental
If you would rather do your own sim on your own schedule, you can rent the whole setup. You get 90 minutes with every station reserved to you, already in race order. There is no queue and no working in. It is $35 for one athlete and $70 for two, on weekdays, in six blocks a day, and you book at least one day ahead. Members book free in the member app.
There is no coach in the room. It is the space and the equipment, not a class, so it suits someone who has seen the stations before. It also suits a lunchtime session, or a wet week close to race day, because every station is indoors. For the running you can take the route around the block outside, or use the assault bikes inside, whichever the weather allows. Details and open blocks are on the sim rental page.
Which one should you pick?
If you are new to HYROX, come to a coached class first. If you want a race-like morning with other people around you, watch for the next sim event. If you know the stations and want a quiet, planned session, rent the floor.
Whichever you choose, treat it as a rehearsal. Learn what you can, write down what you noticed, and take it back into your training for the next few weeks.
If you would like help placing a sim in your build, book your free first class and tell the coach which race you have in mind. We can work out the rest from there.
