Just by fluke ended up in one of the Zwift Training races. They seem rather organized which was good.
What I found hard was knowing whether or not the guys up the road were in the “race” or not.
If there was some way to have more “offical” race times and some sort of of AI lead vehicle.
It would require riders who which to race to “opt in” so to speak, but essentially first person on the road who has “opted in” to the race would have some kind of indication or something.
Either that or different views of the near by riders to show only users who are “opted in” to the race.
