I agree with what @Macy said.
These types of schedules are a bit trickier to integrate into a structured training plan since a large part of the intensity comes from racing once or twice a week.
I like the idea of turning those races into “Group Rides” though! We’ve built some flexibility into our plans for things like this, and now we even have a “Zwift Race” option as well.
Ultimately, you can switch any of your workouts into Zwift Races, Group Rides, or Solo Rides. I’d just make sure that the workout you’re replacing with your races is representative of the effort.
As @Macy said, you can adjust the number of hard workouts per week on your schedule and move things around in a way that will surely work for you.
If you’d like a hand getting things set up, I’d be happy to help! Just shout!
