Create Group or Club Challenges
I would love to be able to set up challenges within groups for the folks that I ride with. Complete with the features that are on the normal Strava challenges such as leaderboards, ranking.
Ability to set up the challenge measurement such as mileage, time, suffer score etc.
I feel like this would really help drive people to ride even harder, especially those that might feel a little overwhelmed by some of the site wide challenges.
