Maybe it’d be better for Zwift to not advertise a specific pace for a group event of riding with the pros. Advertise the ride as an opportunity to ride with World Tour cyclists, and those Zwifters who have the ability can keep up. Don’t advertise it as, for instance, a sub 2.5 w/kg ride when the pros and recently retired pros often aren’t ready to ride at that level, and they soon disappear minutes ahead of those riding the advertised pace.
I agree. However it wouldn’t be that hard for Zwift to implement a similar rubber banding effect that they use in group workouts in group rides perhaps rubber banding everyone to the ride leader’s pace. This would have to be optional of course.
