How can I Edit or Delete an activity?
From your Profile page you can click on an activity to view the details page. From here you can access the Edit and Delete options.
Synced activities
Please note that for synced activities you cannot change the distance or duration. You can, however, modify the type of activity. This is useful when you accidentally selected the wrong activity type on your device or app and want to correct this to make an activity count towards your challenge goal. This option is also available from the Edit page.
Editing an activity might disqualify it
When you edit a synced activity and participate in an event with manual entry disabled, making changes to an activity will remove it from your results.
