If any activity is set to private within Strava, it will not be synced with a Wild Challenge leaderboard. If you wish to have the activity included in any leaderboards, you will need to amend the privacy setting to either 'Followers Only' or 'Public'.

In the interest of openness and fairness, purposefully hiding activities during a challenge period until the end is not permitted as this is not in the spirit of what a challenge represents, and prevents all other members from being able to compete openly.

Purposefully hiding activities until the end may result in those points not being included.
