Apple Watch and Strava not matching

[Liagraceee]

Looking for some help…

My Apple Watch says 8:55 minute miles, but then when I upload to Strava it says 8:27 minute miles, I ran with someone else who’s watch and strava say 8:55 minute miles. How can I fix this problem?

Hey @Liagraceee, 
Thank you for your post and sorry for the delay. I see that your support ticket regarding this has been replied to.

For others that are experiencing this, we found that this had to do with these activities having small areas of bad/invalid GPS data being written to the activity file at the time of recording. Because our system uses the GPS in the file to calculate things like distance and average pace, interruptions there can result in slightly different data on upload compared to other sources like Apple Health. Please also note that Apple in particular has different logic they can apply to handle GPS interruptions in their own ecosystem which we do not have access to.
 
This is simply a limitation of the integration at this time, and looking at the activities in question, things are working as expected.
