Pacer's GPS activity-tracking feature has four different modes: walk, hike, run and ride. Select the correct mode before you start GPS activity. The enabled mode will be displayed in blue.
When you finish the activity, you are able to switch mode on the "save activity" page.
The activity type can also be changed after this activity is saved. Please go to the Home page (the shoe icon) -> Switch to the GPS tab -> History -> Enter a saved activity -> tap the more button (···）on the top right -> Edit.
