The Nike+ SportBand measures distance around 90 percent accuracy. You can improve accuracy by calibrating the Nike+ Sensor to your natural running and walking strides. For best accuracy, calibrate for both walking and running.
Follow these steps to calibrate the Nike+ SportBand Sensor:
- Record a workout on your SportBand of at least 400 meters at a steady, natural pace. For best results, we recommend running or walking at least one mile on a certified track. See more Nike+ Sensor calibration tips.
- After completing your run or walk, plug the SportBand into your computer. If the workout is eligible for calibration, you will see "Calibrate to improve accuracy" in the Nike+ Connect message bar. Within the message bar, click "MORE" to proceed with the calibration process.
- Enter the true distance of your workout and click "Apply." You'll receive a confirmation that your Sensor is now calibrated.
The original, pre-calibration distance will upload to Nike+. The adjustment you make in the calibration tab will be used to improve the accuracy of future SportBand workouts.
