How a workout gets to your watch, and what to do if it didn't

A workout from your calendar goes to your watch on its own: Training Endurance hands it to the watch's service, and the watch picks it up when it syncs with the service's app — for example, Garmin Connect.

Where the plan goes

• Garmin, Suunto, COROS — to the watch.
• Wahoo — to the device.
• Intervals.icu — as an event in the Intervals.icu calendar.
• Google Calendar — as an event in Google Calendar.
• Apple Watch — through the iPhone app, see below.

The plan doesn't go to Polar or Strava: only completed workouts come in from them. To connect a service, see Which watches and services you can connect.

What a workout needs to go

• A structure. Only workouts with a structure — the steps of the workout — go to the watch. Without one, the To Watch button is inactive and says "Add workout structure to send to watch".
• Heart rate zones. Without them, the workout can't be built for the watch. Zones are set in the metabolic profile — see Where zones come from and how to refine them.
• A connected service that takes the plan.

Rest days and events don't go to the watch.

When a workout goes on its own

• Your own workout goes as soon as you save it.
• A workout from your coach goes when it opens for you. Your coach decides when that is: right away, from the Monday of its week, from the Sunday before it, or when they open it themselves. How this is set up: How to connect with a coach.
• A changed workout is updated on the watch too — including when it is moved to another day.

Workouts from your coach open by your time zone: Settings → Settings tab → Time zone. If the zone is wrong, a workout reaches your watch earlier or later.

When a workout disappears from the watch

• when the workout or its structure is deleted from the calendar;
• when it is hidden;
• 48 hours after its date.

In Google Calendar, past workouts stay as events.

Sending by hand

Open the workout in the calendar → Settings tab → To Watch, and choose the service. You will see "Workout sent. Wait 5 minutes and sync your watch."

Sending by hand helps when the workout isn't on your watch: for example, it was deleted on the watch or in the service's app, or sending failed. The workout goes right away and is created on the watch anew.

Only the athlete has the button. If no watch is connected, there's no button, while in the iPhone app it's always there — for Apple Watch.

If your watch has no mode for your sport

Set a replacement: Settings → Settings tab → Send to the watch as → Add a sport. For example, roller skiing can go as skiing. A replacement applies from the next send: workouts already sent aren't sent again.

COROS takes running, trail running, cycling, swimming and strength. HIIT goes to COROS as strength, and skiing, walking and other sports COROS has no mode for go as running.

Apple Watch

Workouts go to Apple Watch through the Training Endurance app for iPhone. You need iOS 18 or later.

1. In the app on your iPhone, open a workout with a structure → Settings tab → To Watch → Apple Watch.
2. If your iPhone asks for permission, allow it.

After the first send, the app keeps the workouts with a structure for the next 14 days on your Apple Watch: today and 13 more. The list is updated when you open the app, and in the background about once an hour, if iOS allows it.

If sending fails:

• "Sending workouts to Apple Watch needs iOS 18 or later. Update your iPhone and try again." — update your iPhone;
• "The app isn't allowed to add workouts to your Apple Watch…" — check the permission on your iPhone: the Watch app → Workout.

If the workout didn't arrive

1. Is the workout open for you? A workout from your coach goes only once it shows in your calendar.
2. Does it have a structure? Without one, the workout doesn't go to the watch.
3. Has your watch synced? The workout reaches the watch when it syncs with the service's app. Open the service's app on your phone and sync the watch.
4. Is there a notice in the workout's window? If sending failed, a notice at the top of the Training tab says "Not sent to …" or "The latest edit did not reach …: it has the previous version". Click Details to see the reason and what to do.
5. Is health data allowed? If you clicked Don't allow on the Health data screen, workouts don't go to your watch. To give your consent again, see Your coach can't see you.

What the notice says, and what to do:

After a failure, the workout isn't sent again on its own: it goes with its next change or with the To Watch button.

A coach sees the same notices in the athlete's workouts. Only the athlete can reconnect a service.
