What should I do if the treadmill distance record is inaccurate?

1) When using the treadmill to save the workout, the "Distance calibration" interface will pop up, where you can enter the actual distance value.

2) When the single running distance exceeds 0.50 kilometers, the calibration value will be recorded by the watch based on a built-in algorithm, and the workout distance will be recorded more accurately next time you use the treadmill.
