The Foot Pod has a typical accuracy of 98%. Calibrating the Foot Pod with the Forerunner can potentially provide greater accuracy.

There are two methods available for calibration. For best results, calibrate the foot pod using the longest distance possible at your typical pace. For the best possible calibration, ensure calibrating over 400 m, ideally 800 m, on a regulation track. Measured tracks are typically more accurate than treadmills.

To automatically calibrate the foot pod:

  1. Navigate to Train Page
  2. If timer is not at 0:00, reset the timer
  3. Press and hold start
  4. Release on start when UNITS appears
  5. Press view to advance to PUSH CALIB setting.
  6. Press start
  7. Run or walk at typical pace for a known distance
  8. Press stop
  9. Adjust the distance1 shown to the actual distance using + and -
  10. Press View to save the calibrated distance

To manually calibrate the foot pod:

  1. Navigate to Train page
  2. If timer is not at 0:00, reset the timer
  3. Press and hold start/stop
  4. Release on start when UNITS appears
  5. Press view to advance to CALIB
  6. Adjust the Calibration factor2 as needed
    • Increase distance by + key to increase calibration factor
    • Decrease distance by - key to decrease calibration factor
  7. Press View to save the calibration factor

Completing calibration of the Foot Pod with your Forerunner 50 can potentially increase the accuracy of the Foot Pod up to 99%.

1Utilize the following information when adjusting the distance:  400 m = 0.25 mi or 0.4 km // 800 m = 0.50 mi or 0.8 km

2The calibration factor for the Forerunner 50 is determined by dividing the True Distance by the Recorded distance of the watch. e.g. You run 500 meters but the watch shows 400 meters. The math would be 500/400=1.250 to be entered. You run 500 meters but the watch shows 600. The math would be 500/600=0.833 to be entered.
