Challenges are based on Central European Time. To receive credit towards a Challenge the qualifying activity 'Mountain Biking'must be tracked in the Outdooractive 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 draw. Prizes will not be given based on leaderboard position or first to complete the challenge but instead by random selection at the beginning of September.
