A GPS error on my Garmin Fenix 3 has led to the watch (and presumably Garmin account) giving me 2 false PBs for fastest kilometre / half mile. It happened between Km's 3-4 of a 12km run. I don't want to delete the whole activity. But I don't want the watch or Connect to credit me with 2 stupid fast PBs. How can I get the PBs deleted without losing the activity?
You usually get the option to accept (or reject) a new record when the data is imported into Garmin Connect - at least you do with my Garmin device that does not identify the records on the device itself like the Fenix 3 does.
You can delete personal records. Simply go to the Personal Records window and select the trash can icon against the record you wish to delete (Whether the record is automatically repopulated with your previous one I do not know)
