I just purchased a forerunner 55, and the distance is not showing on the watch or in the app, when I went for a long walk earlier. Any ideas?
Assuming you recorded an activity as mentioned above, I would typically use the History widget or the Last Activity widget.
History - Displays your activity history and a graph of your recorded activities.
Last Activity - Displays a brief summary of your last recorded activity, such as your last run, last ride, or last swim
