If your last run was indoors, just tap the start button on the Nike+ Running app for Apple watch. If your last run was outdoors, please follow the detailed instructions in the "Nike+ Running app for iOS (Mobile)" above to change your run to an indoors run.
You will need to start a run with these settings from your connected mobile device before you can quick start a run from the Apple Watch using these settings.
Note: If you use the Nike+ Running App for Apple Watch in Indoor Mode, pace and distance are calculated using accelerometer data from your mobile device's built-in accelerometer rather than GPS data. To ensure your motion is captured, carry your mobile device in your hand.
If you carry your device in a pocket or armband, your motion may not be fully captured. If you place your device in the treadmill tray or cupholder, your motion will not be captured.
