A leaderboard is where you can see your progress and ranking in a challenge in comparison to the other participants. We update the leaderboard at least once an hour, so you have the most up-to-date details on your ranking. View the leaderboard by navigating to the challenge and clicking the “Leaderboard” tab.
From the leaderboard you can:
Switch between individual and team rankings
See the three top-ranked people and teams
See every challenge participant and team's ranking
