At Challenge Place we add modalities all the time.
But if you can’t find exactly yours, you can get close enough by using a related modality.
“Beach Soccer” challenge can use the “Soccer” modality to have similar events and statistics (like a goals, assists, for example).
And if you still can’t find a related modality, you can also use a custom one, with basic statistics.
To do this, you must type your modality name (“Beach Soccer”, for example) in the search field, on the challenge creation screen,
After this click on the “Create Now” button.
If you want to suggest modalities that have not been added yet, send the modality name to firstname.lastname@example.org
