We were asked to add overall information to our leaderboard. So we developed the team challenge option, which motivates participants to cooperate. 

In the progress and rank section, you can now select the elements for each of your leaderboards, separately. With team challenge, you set the target distance (sum of all contributed distances) and the title of the challenge. 

The overall challenge is displayed in the leaderboard, directly.
