For swimming activities, you can activate the swim stroke edit mode by clicking on the pencil icon on the section or course map.

In this way, an incorrectly recorded swimming stroke can be corrected. Often the watches, e.g. from Garmin, do not recognise the swimming stroke correctly during swim training and show breaststroke, for example, although the length or lap was done as freestyle.

In Tredict you can get a clean data base by correcting the swimming style or swimming stroke of a length.
