I don’t “know” the directions in Zwift, so if I want to go climb a mountain, show me where this stuff goes so I can decide where I’m actually headed. Or if it’s an easy day, make it so I can avoid climbs. The guesswork is hard sometimes, so there has to be a way to make it so we can choose the route that suits our training.
If you have the new Home Screen this video might help you choose which route you wish to select to give you a ride which meets your training requirements. Route information starts just after 3 min 30 seconds.
not a Zwift feature (yet) but you can use RoadCaptain which allows you to build custom routes and then ride them in Zwift.
Have a look here to see if that is what you need: https://github.com/sandermvanvliet/RoadCaptain/
