Same with me, my personal record in my Stats are not updating. Damn....
Have you looked on the connect website, personal records at the bottom left, and click accept on the records?
Thanks, Spiffman. I just got this. Go to Garmin Connect App bottom right corner and Click More -> Activities -> Running -> View Personal Records -> Accept.
It will look like this after I accepted it.
Then go back to your Stats and all your PRs should be updated by now.
