When the Nike Running app not syncing with Apple Watch, your runs can end up missing from your history, or your Watch may show no workout data at all. In most cases the fix comes down to four things: Bluetooth and Wi-Fi connections, app permissions on the iPhone, Health data sharing, and the Watch’s own software. This guide walks through each one in the order that resolves most problems fastest.

Check the basic connections first

Both devices need a stable link before anything else will work. Apple Watch talks to the iPhone over Bluetooth and, when the phone is out of range, over Wi-Fi or cellular if your model supports it. Start with these checks:

Shopping for one? See our guide: Running App Apple Watch (2026): Which Should You Choose?.

  • Keep the iPhone within about 30 feet of the Watch during the sync.
  • Turn Bluetooth off and back on in iPhone Settings, then confirm the Watch shows as connected in the Watch app.
  • Make sure Airplane Mode is off on both devices.
  • Restart the iPhone and the Watch if the connection still fails.

Grant Nike Running app permissions

The Nike Running app needs access to your fitness and location data to record and sync workouts. Open Settings on the iPhone, scroll to the Nike Run Club or Nike Running entry, and confirm the following:

  1. Location is set to “While Using the App” or “Always,” with Precise Location turned on.
  2. Motion & Fitness access is enabled.
  3. Notifications are allowed if you want workout alerts.

If any of these were off, turn them on, then force-quit the app and open it again before starting a new run.

Confirm Apple Health sharing

Many sync failures come from Health, not from the Nike app itself. Nike writes workout data into Apple Health, so the app must be allowed to save it. Go to the Health app, tap your profile picture, select Apps, and then Nike Running. Turn on Workouts and any heart rate or route data you want to share. If Nike does not appear in the list at all, open the app once while connected to Wi-Fi and wait for it to register.

Update software and reinstall if needed

Outdated software is a common cause of sync gaps. Update the iPhone (Settings > General > Software Update), update the Watch from the Watch app under General > Software Update, and then check the App Store for a pending Nike Running update. If the problem persists, delete the Nike app from the iPhone, restart both devices, and reinstall it. Sign back in and allow the permissions listed above again.

Sync manually to recover missing runs

Runs recorded while the connection was down are usually still saved on the Watch. Open the Nike app, pull down on the home screen to refresh, and wait for the activity list to update. If a run still does not appear, check the Activity app on the Watch to confirm it was recorded there.

Common mistakes

  • Starting a run with the iPhone left at home and expecting the Watch to sync later without Wi-Fi or cellular.
  • Turning off Precise Location, which can stop route data from saving.
  • Denying Health permissions during setup and never re-enabling them.
  • Force-quitting the Nike app mid-run, which can interrupt the save.
  • Assuming a sync failure is permanent before restarting both devices.

A charging stand keeps the Watch topped up so low battery does not interrupt background syncing: View on Amazon.

A sport band that fits snugly keeps the optical heart rate sensor in contact with your skin, which helps the workout data stay complete: View on Amazon.

FAQ

Why does my Nike run show on the Watch but not in the app?

The Watch saved the workout, but the transfer to the iPhone did not complete. Keep both devices close together, open the Nike app, and refresh the activity list.

Do I need Wi-Fi for Nike Running to sync?

Not always. Bluetooth handles most syncing when the iPhone is nearby, but a cellular or Wi-Fi connection helps when the phone is far away.

Will reinstalling the Nike app delete my run history?

Runs saved to your Nike account stay with the account after you sign back in. Runs that were never uploaded may be lost, so check the Watch and sync first.

Conclusion

Most Nike Running app sync problems clear up once Bluetooth, app permissions, and Health sharing are set correctly. Work through the steps in order and restart both devices after each change. If the issue continues after a full reinstall, contact Nike support with your device models and software versions.
