Yes. When submitting ride data for a day you will be required to specify a public GPS activity link for that ride.
No data submission will be allowed without a public GPS activity link.
The minimum distance which has to be submitted is 5 km. No distance less than 5 km will be accepted in the system.
Every submitted activity link should be public so that anyone can open and thus view your ride-data, without the need for any special access, at the most by logging in to their own app account for the app using which the ride data was submitted.
