Milestones and exploration

Overview shows milestones such as your first 100 km or 100 miles, depending on your units.

The Exploration score shows how much of an activity was new to you, compared with your earlier tracks. It is shown as a percentage.

The score only knows your imported tracks, not every place you have been. Duplicates, hidden tracks, and GPS gaps affect it. Importing older tracks can change the score of later ones once they are recalculated; check Settings → Processing.

See the calculation for details.
