why don’t put racetracks in Zwift? It will be great to race on famous racetracks like Mugello in Italy, Phillip Island in Australia, Costa in US (just to mention racetracks with uphills and downhills). Before COVID Monza racetrack organised the 12 hours Monza, a great roadbike race with many riders. It would be great to race virtual “Crit races” on real racetracks. Racetracks are already on many video games so it could be also pretty easy to put them on Zwift.
It would not be easy since Zwift uses it’s own game engine.
