If a run synced twice, or if you accidentally logged a workout you didn't complete, you can easily delete it from your URUNN calendar.
How to delete a run:
Open the URUNN app and go to your Plan tab.
Tap on the specific run you want to remove.
Tap the trash can icon located on the right side of the screen.
Confirm the deletion.
Note on synced runs: If the duplicate run was automatically imported from a connected app (like Garmin Connect or Apple Health), you may also need to delete the duplicate entry from that source app to prevent it from syncing back into URUNN on your next refresh.
