Calibrating using your last workout:
If you have an iPod nano (4th generation) or iPod touch (2nd generation), you can calibrate Nike + iPod using the workout you just finished. This is useful if you’ve traveled a known distance that doesn’t match the summary distance displayed on your iPod. At the end of your workout:
iPod nano (4th generation)
- Press the Center button, and choose End Workout.
- At the Workout Summary screen, press and hold the Center button.
- Choose Calibrate.
- Select the actual distance you walked or ran, and press the Center button.
iPod touch (2nd generation)
- Tap End Workout.
- At the Workout Summary screen, tap Calibrate.
- Select the actual distance you walked or ran and tap Done in the top right corner.
- Tap Done at the Workout Summary screen.
iPod detects whether the workout was a walk or run and correctly uses the new calibration in place of the existing one.
Additional Information
Note: Even after calibrating, the accuracy of the distance measurements may vary depending on gait, running surface, incline, or temperature.
