You can't. See the ';Calibrate your Apple Watch' section in:
Calibrating your Apple Watch for improved Workout and Activity accuracy - Apple Support
"Whenever you walk or run outside using the above steps, your Apple Watch continues to calibrate the accelerometer by learning your stride length at different speeds."
