How to Connect Apple Watch to 42Runs

Apple Watch talks to 42Runs directly on the iPhone.

Connect

1. Open Settings → Connect Your Watch in 42Runs on iPhone.
2. Choose Apple Watch.
3. Tap Connect.
4. Allow 42Runs to schedule workouts on your Apple Watch, then allow it to read workouts and heart rate from Health.

When both prompts are finished, the Apple Watch row shows Connected. That means the connect flow completed. Apple does not tell apps whether every Health type was granted, so if completed runs never appear, check iPhone Settings → Privacy & Security → Health → 42Runs and make sure workouts and heart rate are on.

What syncs

• Planned workouts go to the watch. Sessions you add to the calendar are scheduled on Apple Watch. For a training plan, 42Runs sends one week at a time and stays a week ahead, the same rolling window as other watches. Later weeks follow as they come up.
• Completed runs come back. After a run, 42Runs reads the workout from Health on this iPhone and includes it with your other activities, so it can be matched to the planned session for that day and feed Training Load, Fitness, Fatigue, and Form.

You do not need intervals.icu for Apple Watch. If Garmin (or another brand) is also connected, you can have both at once. Activities from both sources are kept; they are not merged into a single duplicate-free list.

Adding a plan

A training plan can be added when a connection can receive workouts. Apple Watch counts for that. Polar does not, until Polar allows planned workouts to be sent.

Disconnecting

On Settings → Connect Your Watch → Apple Watch, tap Disconnect. 42Runs stops using the permission. Garmin, Polar, and the pairing-service brands are unchanged.

Disconnect in 42Runs does not revoke Health access. To turn that off completely, open iPhone Settings → Privacy & Security → Health → 42Runs.

If workout scheduling was denied at the prompt, you can change it later in iPhone Settings → 42Runs.
