How should a single class be structured?
The session type that matters most is compromised running. Athletes run immediately after station work so their legs learn what a 1km run feels like when already fatigued, which is the specific skill the race tests.
A workable sixty-minute session looks like this:
Keep running volume above station volume in every session. The most common programming error is inverting that ratio because stations feel more like coaching.
In the first peer-reviewed study on the format, athletes spent 79.5% of the race between 90 and 100% of maximum heart rate (Brandt et al., 2025). That is the intensity your classes need to rehearse. It is also why two sessions a week is plenty alongside a client's own running.
The same study found that finishing times correlated with VO2max and endurance training volume, while grip strength and muscle mass showed no correlation. The strongest person in your class isn't automatically your fastest finisher, and telling them so early saves frustration later.
What does a training week look like?
A class is one input. Members who only attend your sessions will not finish well, so publish a weekly structure they can follow around them.
Four to five training days suit most members. The two non-negotiables are one genuinely easy aerobic run and one session where running and stations are combined under fatigue.
How do you scale a mixed-ability class?
Scale load and distance, never the movement. Everyone in the room should be doing the same eight patterns, because the race gives nobody an alternative.
Mixed groups break down on run intervals, since a 400m interval takes one athlete ninety seconds and another three minutes. Switch to time-based intervals rather than distance-based ones, so the whole class starts and finishes together, and nobody trains alone at the back.
For station work, set three load tiers and let athletes self-select. Publish the actual division weights alongside your tiers to help people place themselves honestly, and turn your class into a benchmark rather than a workout.
Once you have enough demand, stream the class instead. Run a fundamentals session for first-timers and returners, focused on movement quality and building a base, and an advanced session at race pace with competition intensity. Streaming solves mixed ability better than any amount of in-session scaling.
This is the exact question new race-prep coaches ask when they start:
From your perspective, what should I consider when planning and running HYROX classes? What would you personally like to see, experience, or get out of a class?

The answers that thread attracts point the same way every time. People want structure they can measure themselves against week to week, not a different hard workout each session.
How many people can you put in one class?
Equipment access sets the cap, not floor space. If you have one SkiErg and one sled lane, a class of twenty means people queue, and queuing kills the intensity the session depends on.
Larger commercial gyms run classes above twenty by rotating groups through stations in waves. Most independent gyms cap at eight to twelve, which keeps rest honest and lets the coach correct movement instead of managing traffic.
Work backward from your bottleneck station. Count how many athletes can be working at once on your scarcest piece of equipment, then multiply by your rotation depth.
What equipment do you actually need?
Full specification means a SkiErg, a rower, a sled with a lane long enough for 50 meters, wall ball targets, kettlebells, and sandbags. Most gyms have half of that.
The sled is the usual gap and the easiest to work around. Prowler pushes, heavy sled drags on turf, banded marches, and weighted carries all train the same pattern: driving horizontally under load with a compromised heart rate.
A rower and a treadmill will carry most of a twelve-week block. Equipment gaps change how closely you replicate the race, not whether you can train for it.
Kitting out a dedicated space to full specification runs into five figures once you count ergs, sleds, and flooring. Adding race-style programming to equipment you already own costs nothing, which is why almost every gym should start with the second route.
Do your coaches need a certification?
You don't need certification to program race-style training at your own gym. Affiliated clubs get access to official coach education, and official foundation and race-ready courses are available.
Be clear-eyed about what they cover. A published review of the official foundation course notes that it does not address class management, how to structure a class, or how to facilitate one. It qualifies someone to instruct the movements rather than to build a program.
That gap is yours to fill. A coach who already runs good group sessions and understands interval structure will deliver a better class than a certified coach who has never managed a mixed-ability room. Hire and develop for class management first, then add the movement credential.
Should you become an affiliated training club?
No, not necessarily. Any gym can program race-style training and market it as hybrid fitness or race prep. Without affiliation, you can't use the brand name, logo, or trademarked vocabulary in your marketing, because those are owned and enforced.
Affiliation comes in two tiers. The Training Club tier is open to any gym, with no minimum equipment requirement. It gives you brand usage, a directory listing, programming hub access, and pre-sale ticket windows for members.
The higher Performance Center tier requires around 1,900 square feet of dedicated floor space and specified equipment, and comes with geographic exclusivity.
The commercial case rests on member acquisition, not programming quality. Annual fees sit under the cost of retaining one member for a year, so a single sign-up who came for the directory listing covers it. Terms run twelve months and auto-renew unless canceled sixty days before the end, and current pricing is published on the official affiliation portal.
What does a twelve-week block look like?
Anchor the block to a real race date and work backwards. Members train differently when a deadline looms, and money is already spent.
Weeks one to four: base and technique. Build running volume and teach the movements, keeping intensity moderate. Most members have never touched a SkiErg, and technique work is cheapest while they are fresh.
Weeks five to eight: compromised running. Run and station pairings get longer, rest gets shorter. This is where most of the adaptation happens and where attendance usually dips, so it needs your best coaching attention and your most deliberate encouragement.
Weeks nine to twelve: specificity and taper. Add one half simulation around week nine and a full simulation around week ten, then reduce volume while holding intensity. A simulation four weeks out gives an athlete a real split sheet and a reason to keep showing up.
Running and lifting in the same block creates known tension, since endurance work can blunt strength adaptation when you stack the two carelessly. Knowing how to structure concurrent training keeps a twelve-week build from flattening both qualities at once.
How do you measure whether the training is working?
Total time on a simulation is a blunt instrument. Run the same short test every four weeks instead: a 1km run, then fifty wall balls, then a second 1km run.
The number that matters is the gap between the two runs. That drop-off measures the exact quality the race punishes: running on legs that are already cooked.
It is also the pattern the Frontiers study captured across its sample, where running took 51.2 minutes of an 86.5-minute median finish. An athlete whose drop-off shrinks is getting race-fitter, even if their total time hasn't moved.
Track it per athlete and show them the trend. Visible progress on a single honest number does more for retention than any amount of encouragement.
How do you fill the class and keep it full?
Sell cohorts, not class passes. Pick a race three months out, recruit a group to enter it together, and sell the twelve-week block as the preparation. The deadline does the selling and the group does the retention.
Two pricing models work:
Monthly Subscription
A monthly subscription on top of membership gives predictable revenue and suits gyms running classes several times a week. Published examples sit near $45 a month, with drop-ins around $20.
Fixed-price Plan
The alternative is a fixed-price block tied to a race date, which converts better and earns more per head. 365FIT sells its ten-week race-prep block that way, as a single A$169 payment covering the sessions, run intervals, and a weekly coach check-in. They run their site and member app on FitBudd.
Two details there are worth copying from here. They bundle nutrition tracking and a recipe library into the block, which lifts the price without adding coaching hours. The weekly check-in gives members a reason to stay engaged through the mid-block weeks where attendance normally falls.
Run a monthly benchmark session that anyone can attend, members or not. It is your best acquisition tool, because it gives a prospect a number and a reason to come back for the next one.
The delivery problem is the same across both models. A block runs across months and mixed-ability groups, and rewriting it each week does not scale past one class. Coaches who build, save, and deploy workout templates can run the same progression across several groups while still tracking each athlete's numbers individually.
