Keep the set structure
Distance work, fixed-time recovery, warmup, cooldown, and supported goals become native Workout app steps. Repeat blocks stay grouped.
Compatibility and setup
Swimming device support
Use this page to check how a pool swim reaches Apple Watch, what the watch guides and records, and how to move a planned workout to Garmin or another destination using a file you control.
At a glance
Choose the path your swim device can use.
Apple Watch receives a native workout. Garmin and generic destinations receive a planned-workout file. Text is reference only.
| Device or destination | What works | How it gets there | What you do |
|---|---|---|---|
| Apple Watch iOS 18 and watchOS 11 or newer | Native custom pool swim with distance sets, timed recovery, grouped repeats, step names, and eligible target times | Apple preview | Preview the workout, allow scheduling, add it to the Workout app, then enter the pool length when the swim starts. |
| iPhone by itself | Workout instructions, target preview, export setup, and manual completion log | Reference only | Slow N Steady does not run a swim session on the iPhone. Use a swim-capable watch or follow the written set at the pool. |
| Generic pool-swim FIT file | Planned workout marked Swimming / Lap Swimming with pool length, ordered distance and recovery steps, intensity, and notes | File sharing | Choose 25 yd, 25 m, or 50 m, then save to Files, AirDrop, email, or move the .fit file to a computer. |
| Compatible Garmin pool-swim watch | The same lap-swimming planned-workout .fit file | USB transfer | Copy it to Garmin/NewFiles, safely eject, then check pool-swim Workouts on the watch. Model acceptance varies. |
| Wahoo | No swimming workout destination in Slow N Steady | Not supported | Use Apple Watch, a compatible Garmin, the generic FIT file with another proven receiver, or readable text. |
| Readable text | A human-readable step summary with distance, recovery, and zone guidance | Text sharing | Save or send it for deck-side reference or manual entry. It is not an importable workout file. |
Apple Watch
Add a native custom pool swim.
Swimming custom workouts arrived with iOS 18 and watchOS 11. Slow N Steady checks Apple's support and scheduling permission before adding one.
Use swim CV
When swim critical-velocity pace is saved, eligible distance steps also receive a target time. The step advances after its distance and time goals are complete.
Set pool length on Watch
The Workout app asks for pool length when the workout starts. Slow N Steady does not preselect it in the Apple Watch handoff.
Record in Apple's Workout app
Apple Watch records the swim in Apple's system. Slow N Steady does not currently receive the completed Watch workout back automatically.
This is a pool-swimming path.
Slow N Steady creates the Apple workout with an indoor swimming location. It does not create a structured open-water swim. Stroke and equipment prescriptions are not added because the current workout catalog does not prescribe them.
Requirements:Use an iPhone running iOS 18 or newer and a compatible paired Apple Watch running watchOS 11 or newer with the Workout app installed. Allow Slow N Steady to schedule workouts.
Workout files
The swim FIT file is a planned pool workout.
It is not a completed activity, an account sync, or proof that every watch and app accepts imported swim workouts.
Garmin compatibility:The file is marked Swimming / Lap Swimming and includes your pool length, distance sets, timed recovery, intensity, and notes. The file itself has been validated, but behavior can vary by device. Test a short workout on your watch first.
Choose the actual pool
Select 25 yd, 25 m, or 50 m before building the file. Garmin's FIT swim-workout profile requires a pool length.
Keep valid swim steps
Active sets use distance. Recovery uses time or an open lap-button step. Repeats are expanded in order for broad file compatibility.
Keep pace as guidance
Saved swim CV adds personal pace text to step notes. FIT's swim target field is for stroke, so Slow N Steady does not invent a portable pace target or stroke.
Transfer the file yourself
Use Files, AirDrop, email, or a computer. For Garmin, copy to Garmin/NewFiles; do not use the completed-activity Import Data page.
Garmin pool workouts require a pool length. Active sets use distance, while recovery uses time or an open lap-button step. See Garmin's pool-workout tips.
