The cycling data I recorded with the Apple Watch Workout app shows a significant difference in Strava compared to the data in the Fitness app on my iPhone after importing.

Hey ​@Piggy
The data discrepancy that you're seeing is due to how we analyze the activity file that is synced over. During your activity, the information that you're seeing on your Apple Watch is derived from the Watch's pedometer or accelerometer.

Once your activity is uploaded, our calculations are based on the GPS data that are recorded in the activity file. GPS data is only written to the file after a GPS connection has been established.

If there is any interruption with the GPS data that was recorded, it can affect the data we're presenting.

You should also check the settings on the watch. Things like auto pause on/off can make a big difference.
