I find myself using it ahead of time to see route and segment profiles, and then during a ride to give me an idea of what’s ahead on a route I’m riding. You can search by route name, sort by world, distance, elevation gain etc.
Big shout-out and thread bump: @andipaetzold recently updated ZwiftMap.com to reflect the latest Urukazi expansion of Makuri!
Really loving being able to “scrub” through the new routes to get to know them.
If you haven’t used ZwiftMap.com, to explain: you can roll your cursor over the route profile on the left and the corresponding point will show on the map on the right. I find this the best way to do “route recon” - knowing how far into a route a sprint or KOM are.
That is the program for planning out my own routes for longer rides or reviewing a ride. Plus shows where non tarmac sections with their distance. Best option out there. Too bad not easy to input into zwift for a custom route. Have to write down or remember the turns to a custom route.
