Hi ​@MakeStravaGreat 

Thanks for your post. Currently, offer the following types of group Challenges:

• Most Activity: See who can log the most time, distance, elevation gain, or loss. You can set an optional goal, which establishes a milestone for the group to reach. The leaderboard ranks athletes by their overall activity.
• Fastest Effort: Average pace across a specific distance via running, virtual running, or wheelchair. Setting a race distance gives athletes in your challenge a guide on how far they should go. This is the distance all efforts will be measured over, and the leaderboard will rank runners by their average pace.
• Longest Single Activity: Single activity recording of your longest distance across any sport that supports distance. The leaderboard ranks athletes by who has recorded the activity with the most distance.
• Group Goal: Chase a goal as a group. Choose between a time, distance, elevation gain, or elevation loss goal; all activities will count towards the single goal. There is no leaderboard, but you can see how you’re contributing to the group effort.

Can you provide more details on what additional types of group challenges you were hoping to see? Thanks so much.
