When doing an FTP test workout the test interval doesn’t have a target, so Zwift doesn’t insist you speed up or slow down. It also shows the interval average, which is very helpful.
I’m trying to create custom workouts with test intervals to get peak 1, 3, 5 minute power.
Hi Peter,
At the moment we have the “free ride” function in custom workouts where you can push as much as you want for as long as you want. Is that what you looking for?
You’re right, looking at it closer free ride works.
It would be nice to display the average, but free ride works for now.
Hi Peter,
Ok, great new! I’m glad you found what you were looking for.
Regarding the average value - I’ll add it on the request list for you and if we get many people asking about this feature we’ll put in on the radar 
In meantime Ride On!
Thank you
On the above, I am trying to build a custom workout to do 1, 3 and 5 minute power test.
How can I do this to get avg. I see to do in free ride, how is this done?
