The Leaderboard  shows the winners or current leaders of the event. Through the settings at the bottom of the screen, you can select a Ranking and a number x so that the first x participants in each group of the ranking will be shown.

If you would like to show different columns (or use a different format), you can also select a List from which the column settings will be taken.
