Low-Turnout Classes: When to Cancel and How to Tell Athletes
Set a minimum per class, decide hours before, tell athletes and offer another slot, and use attendance to fix the slots that never fill.

The 7 am and 7 pm classes fill up; Tuesday's 3 pm has two people booked. Running it costs an hour of coaching and keeps two athletes happy. Cancelling it late leaves those two without a plan and with the feeling that the schedule cannot be trusted. This guide is about deciding earlier, with a rule athletes know, and about what to do with classes that never fill.
What an empty class costs
The sum is simple: what you pay for that coaching hour against what the class brings in. What it brings is not only the fees of those who come, because you collect those fees anyway if they train at another time. What you lose by cancelling is trust, and the odd member who can only train at that hour.
| Situation | What usually makes sense |
|---|---|
| A quiet class now and then (bank holidays, summer) | Keep it, or let the automatic minimum apply that day |
| The same slot quiet week after week | Change the schedule: move it, merge it or drop it |
| A slot with few but loyal athletes | Keep it with a lower capacity or turn it into open gym |
| A new class with no regulars yet | Give it a fixed number of weeks before judging it |
What does not work is deciding by eye, every day, at the last minute. The athlete who arranged their day to come cannot tell «too few people» from «the box cancels when it feels like it».
Set a minimum and say so
The rule has two numbers: how many bookings the class needs to run and how long before the start it is checked. For example, «if fewer than three people are booked two hours before, the class is cancelled». With the rule written down, cancelling stops being the coach's call and becomes something everyone knows.
Publish the rule where athletes will see it: the box rules, the website and the welcome message. If you change the minimum, tell them before it applies.
When to decide: how many hours before
The earlier you check, the more room the athlete has to switch class or make other plans; the later, the more last-minute bookings come in. Two hours before is a reasonable starting point for morning and evening classes. For the first class of the day, check the night before: nobody looks at their phone at 5 am.
A practical detail: make the check time match the free cancellation deadline, or come before it. If a class can be cancelled for free until two hours before, checking the minimum at that moment stops a late cancellation from leaving the class under the minimum when nobody can react.
How to tell athletes
If the class is cancelled, everyone booked must know right away, not at the door. The notice should say which class it is, that the session goes back to their balance and why it was cancelled. That way nobody has to message the box to ask whether they lost the class.
If you would rather merge two classes than cancel, tell them with the same care and offer the concrete alternative: «The 3 pm joins the 4 pm, your place is booked».
Offer another slot
The best answer to a cancellation is a nearby alternative. If the next class has room, say so in the same message. If it is full, the waitlist helps that place reach whoever needs it: how to share places fairly is in waitlists for CrossFit classes.
For slots that are always quiet, ask the people who do come. Sometimes the 3 pm does not fill because 2 pm fits lunch better, and moving it an hour solves more than any minimum.
Review the schedule with attendance
Once a quarter, look at how many booked each class over the last few weeks. Three questions are enough:
- Which slots are under the minimum more than half the time? They are candidates to move or go.
- Which slots always fill and have a waitlist? There may be room for one more class.
- Are there two classes in a row, each half full? Merging them frees a coaching hour without leaving anyone out.
Change the schedule in advance and at the start of a month or a cycle, not midweek.
How Wodmark does it
In Wodmark the minimum is set on each class type, in «Class types»:
- «Cancel if fewer than (0 = never)»: the minimum number of bookings. With 0, the class never cancels itself.
- «Check minimum (min before)»: how many minutes before the start it is checked; 120 by default and one day at most.
At that moment, if the class has not reached the minimum, it cancels itself. Everyone booked, everyone on the waitlist and anyone with a pending request gets a notice in the app, or by e-mail if they do not have the app and have not turned those notices off. The notice says the class is back in their balance and that it was cancelled for lack of bookings. You can also cancel a class by hand, with the same notice: the steps are in cancelling a class.
To offer another slot or announce a schedule change, notices to athletes reach everyone or only those who can book that class type. In «Classes» you see, for each session, how many booked against the capacity, which is what you need to review the schedule. The weekly schedule is changed in «Schedule»: here is how.
Frequently asked questions
What is a good minimum for a CrossFit class?
It depends on what the coaching hour costs you and on the class type. Many boxes use between two and four. Start low and raise it if the rule almost never applies.
Does the athlete lose the class if it is cancelled for lack of people?
They should not. If the box cancels, the session goes back to the athlete's balance. In Wodmark that happens automatically, whether the class is cancelled by hand or for not reaching the minimum.
What if someone books right after the check?
Once the class is cancelled, it can no longer be booked. That is why the check time should be known and not too early: whoever wants to come knows how long they have to book.
Wodmark handles bookings, waitlists and each class's minimum without anyone checking the list by hand. See Wodmark for boxes.
