create a route and ride virtual?
 

Is there a website where one can upload a custom created route and have two remote riders ride it together, from two different locations. Both have Computrainers.
Zwift only has 2x2 routes. We want to upload, or pick from a large library.
Thanks -

Tourdegiro.com will do this

I don't see where I can upload or schedule a ride. (I am not yet a paying member, so some tabs/options may be absent.)

Yes you have to login to see that functionality. They give you a no-strings-attached 2 week trial though.
