I would like to see trial riders ineligible for KOMs. Too often some 10 watt/kilo super freak is on the course. I suspect some of these are trial riders.
If you are on a free trial an get the KOM, then a message should flash saying “if you were a Zwift member, you would have a polka dot jersey and KOM” etc.
This would stop the riders who like to game the system and sign up with a new email address every 50 km. And make the free trial for 30 km!
