How about a new virtual world that is filled with famous TDF climbs with the alternate routes of those climbs included.
THis has been suggested numerous times on the forums. Make sure you vote up the existing requests so Zwift knows what the users want.
I would love to see real world climbs ‘virtually’ linked to one another and to Watopia or whatever.
For example, add a spur road to London off of Watopia and one to Richmond and back again to make all linked in giant loops.
We could then solve the problem of too many riders on course, but we would still have to ride from place to place and not just pick a server to jump onto for a given ride location.
In the virtual world, there is no reason why we can’t ride up the Tourmalet and then turn left to ride up Stelvio…
