Hi @FlorisStrava

Thanks for posting. Strava supports a number of activity types. You can see the full list here. 

If you would like to request a new sport type, we welcome you to submit it as a new idea. You can read more about how this works in our Guide to Feature Suggestions.

Volleyball has already been suggested and you can add your vote here. For bouldering & korball, you can submit those as new ideas. We kindly ask that you review our Ideas guidelines, particularly the “What makes a good idea” section, to ensure that your ideas are clear, concise, and can reach as many others as possible.

Thank you for your contribution, we value your input.
