Earlier today the August guest world calendar was released by Zwiftinsider. On the calendar it does not yet say that france and paris are going to be in the rotation, but Eric Schlange, author of zwiftinsider think that Zwift will add it into the schedule soon. Usually there is a Zwift update each month with bug fixes/new features/etc. This update could contain an update that allows zwifters to freeride in france or paris.
Thanks for reading! There will be an article later today containing what I think will be in the coming update. Ride On!
