Members Completing the Challenge Route
Map challenges have an end point which members will reach by completing the challenge's step goal. This challenge step goal is the daily step goal multiplied by the number of days in the challenge.
If someone reaches the end of the challenge map, their map icon will remain at the endpoint and they will no longer receive milestone emails (if it's a map based challenge). They can still record steps, and they will continue to add to their challenge total on the leaderboard until the end of the challenge.
