Challenges are based on Central European Time. To receive credit towards a challenge a qualifying activity (Hiking, Mountain Biking, etc) must be tracked in the Outdooractive or partner app. Outdooractive community guidelines must be followed, including health and travel restrictions in your area. Completing a challenge goal does not automatically grant a prize. In the event of a prize giveaway, users who achieve the challenge goal have the option to enter a drawing. Prizes will not be given based on leaderboard position or first to achieve.
