First, thank you Zwift for making the Custom Workout builder!
The interface is intuitive and easy to use. I was able to quickly build a workout.
There are a couple of problems that I found though.
When using the Interval Block, I could not set the Rest Duration shorter than :30 seconds. Hunter Allen @ Peaks Training loves Microburst intervals and I won’t be able to create a workout for this unless I can set the Rest Duration to :15 seconds.
I then tried to create a Microburst set by simply using Zone 1 and Zone 6 blocks strung together. I could set the Interval and Rest Durations to :15 seconds each but then when I start the workout, the Rest Durations are incorrect with some added time to them.
When I opened the Zwift Workout files (.zwo) in my Documents/Zwift/Workouts folder, I see that the values for the Rest Durations are also incorrect there.
So if I manually modify this file and set the Duration to what I want, it appears to work.
So what’s with all the decimal values with a fair amount of significant digits for Duration? I see a potential rounding error going on.
