Actually. I’m not to social as far as cycling goes. It’s really pretty annoying to have someone yapping at me while I’m suffering up a KOM, so whether there are other riders on the course is not an issue. RGT, the program I’m reference, does allow group invites, and even has semi-programable bots if you have to satisfy the itch for companionship during the ride.
The value of being able to have instantly accessible familiar (or unfamiliar) courses is the same as having Zwift in general - to be able to train when you can’t go outside. Case in point, I have a Gran Fondo pretty close to the beginning of the outdoor ride season. It’s a couple of hundred miles away, so it’s not something I’m going to be driving to ahead of time to ride in the cold rain and/or snow. Having the route, even if it is just the road only and some generic terrain, available in Zwift in order to be able to familiarize myself with the map and gradients would be a great plus, until I can get out to train on some real hills.
