Bumping this back up now that Race Event Calendar, Videos, & Results - Zwift and the monthly calendar is a thing (yay!). It would be great if the 2023 dates for ToW, TdZ, Zwift Academy, etc could live here so that people could choose to plan their training around these flagship events with multiple months(?) notice. This would also give clubs the opportunity to engage their membership in training for specific series together.
A brief search showed that are a few other forum posts that are related to having more visibility into the longer term race calendar as well, so it suggests this is something the community is asking for:
Race Calendar (@Fran_Bambust)
Annual Calendar for Upcoming Tours? (@Devin_Columbus)
Zwift Fondo series? (@Hatch)
