How can I schedule a road bike course and add it to my calender?

I'm probably asking a similar question. I'd like to know if you can import a Swift ride into the Garmin Connect calendar.

Have you done a ride with Zwift or do you plan to do a Zwift ride and schedule it in the calendar?

A scheduled ride is either a workout or an event (like a race). Create a workout in Garmin Connect and schedule it.

If you mean that you want to import a ride you've done with Zwift you can just connect Garmin Connect and Zwift and all rides will automatically be imported into Garmin Connect. Maybe not possible to do afterwards. In that case you will have to export from Zwift and then import into Connect for those past rides.

I would like to do the latter, to plan a Zwift ride and then add it to the calendar. The Zwift rides I have completed automatically upload to Garmin Connect.

If you create a workout (https://connect.garmin.com/modern/workouts) in Garmin Connect then you can add that workout to the calendar. There is no function to plan any activity in the calendar.

If it is a race or event in Zwift that you want to add you can create a new event for that and add it to the calendar. I did a search and found two Zwift ZRS events added.

Ok thanks!
