The format is easy to describe and hard to resist: a fitness race that alternates running with a fixed set of functional stations — sleds, ski and rowing machines, lunges, wall balls — with events in cities around the world and a finish time you can compare to last year's. It has done for functional fitness what marathons did for running: given ordinary athletes a date to train for. And so gyms and studios everywhere are adding race-prep classes, because the demand is real and the classes fill.
They also empty, and that is the part nobody plans for. Demand that comes with a date leaves with it. Here are the numbers to read before you add the program, the one that sizes the class, and the cliff after race day that decides whether the program grew your studio or borrowed from it.
1. Demand — persistent, not a survey
A poll in the group chat will always say yes. The demand worth building on is persistent: members who have asked more than once, members already training for a race somewhere else, a waitlist on the strength or HIIT slot that keeps forming. And it has a shape — interest peaks in the weeks after a local event announces its date. Read it over a month, not a day, and note where it sits on the calendar, because the calendar is going to run the program.
2. Capacity — stations, not square feet
A race-prep class rotates athletes through the equipment you own, so its capacity is the station count times the athletes per station, not the size of the floor. Two sleds and two ski machines run twelve comfortably in pairs; twenty-four needs twice the kit or half the quality, and the athletes can tell which. That makes the break-even math a per-class calculation with one extra line — the equipment, amortized across the classes it will serve.
Five of twelve is a comfortable line, which is why these classes look like easy money in month one. The line only becomes a problem after the race, when a class built for twelve is running at four — and that is the number to plan for before the first athlete signs up. The fill-rate piece has the general break-even method; the equipment line is the only addition.
3. The calendar runs the program
Build the program backward from the race. A twelve-week block that ends one to two weeks before the local event fills on the day the event date is announced and peaks in attendance in the final fortnight, when the goal is closest. A block that ends six weeks before the race loses its athletes to the gap; one that ends after it never had a finish line. Every intake, therefore, has a date, and every date has a cliff on the far side of it.
4. The race-day cliff
Here is the number that decides whether the program grew the studio. Keep the intake together as a cohort and watch each athlete's weekly attendance against her own program pace, from the last week of the program, through the race, and for eight weeks after it. The shape is the one every event-shaped program produces.
Both lines fall — a studio that expects no drop after race day will misread a normal one as a failure. What separates them is a single conversation, and its timing. The athlete who hears "the next event is in March, and here is what we do between now and then" in the final week of the program, while the goal is still hot, tends to continue. The one who hears it three weeks after the race, in an email, has already gone back to the strength class she came from, or to the studio down the road that answered first. The post-challenge piece is the same cliff in a different room, and the same fix.
5. Program-to-member conversion, by intake
Count it from the program start, and only for athletes who were not already members: program starters holding an ongoing membership 60 days after race day, divided by program starters. Report it per intake, so the March cohort sits next to the October one and the next-goal conversation can be judged by what it changed. And watch the other direction too — cannibalization. If the race-prep class filled while the Tuesday strength class emptied, the program moved members around; if total attendance rose, it grew the studio. That test is the only honest one, and it takes a month to run.
| # | The number | How to compute it | When it moves |
|---|---|---|---|
| 1 | Persistent demand | repeat asks, waitlists, race dates announced | before the launch |
| 2 | Station capacity | stations × athletes per station | the day you buy equipment |
| 3 | Break-even per class | (coach + room-hour + kit) ÷ revenue per athlete | every class, especially after the race |
| 4 | Pace after race day | each athlete's weekly visits ÷ her program pace | weeks 2–4 after: under half = reach out |
| 5 | Program-to-member | holding a membership at +60d ÷ starters, not already members | the final week's conversation |
| 6 | Cannibalization | total attendance, all classes, before vs after | a month after launch |
Where the numbers live
Whether the studio runs on Mindbody or Mariana Tek, the platform already records who bought the program, when it started, every class each athlete attended, and what she bought after the race. The cohort, the pace, and the conversion are all derivable from that. What has to be added is keeping the intake together as a group after the finish line and watching each athlete against her own pace — and the conversation, in week ten, from the coach, which is exactly the thing that gets lost in the excitement of race week.
That is the shape Xyzios gives a studio running race-prep classes. It connects on top of Mindbody or Mariana Tek — the platform stays your system of record — reads the studio's own history through the day, sets each class's attendance against a break-even headcount estimated for the location from your books (the equipment line is yours to add), and puts the members whose visits fall away after the race on the At Risk list, with a save note drafted for the highest-risk ones, ready for your approval. The next-goal conversation stays with the coach, in week ten. Nothing reaches an athlete without your approval, and nothing is written to Mindbody except what you tap or approve.
Wherever you run the numbers, decide the day-after offer before the day-one sale. The race fills the class. What you say in week ten decides whether it stays full. See how the board reads a program-based studio, or read the break-even method the station math is built on.
