I’d like to create longer Zwift workouts that would include some structured intervals interspersed between longer periods of virtual riding (allowing the trainer to respond to terrain changes). In a .zwo file, the way to do this is to add the FlatRoad=(“0” or “1”) modifier to a freeride interval. I normally download the zwo file from TrainerDay and then manually edit the file to specify FlatRoad=“0”; is there a way to do this directly within the workout creator?
No there is no way to do this now. I did not even know about this flag/feature. Let us research this but again this is a a feature request.
Funny you don’t recognize the feature, because the .zwo files I created in TrainerDay export with the Flatroad specified:
<FreeRide Duration=“300” FlatRoad=“1”/>
I think the Flatroad modifier only works for free ride segments. With winter coming up, the idea would be to replicate an outdoor ride that may include a few intervals over the course of a longer ride. While intervals are relatively engaging, pure endurance blocks can be mind-numbing on the trainer, and I find the terrain changes in Zwift help combat the boredom…
Oh yes. We worked on ZWO a long time ago and I was not doing the heavy lifting for this part so I forgot… Yes we just added a similar feature to our app, but I fully appreciate the need for the visual stimulation of Zwift. I need to read on this. Maybe we can use our new slope feature to translate to this flatride.
I don’t think it needs to involve the slope feature since a zwo file only allows FlatRoad=“0” or FlatRoad=“1”, so It’s simply a matter of changing the value generated as a zwo is downloaded. I was thinking that instead of entering “FR” in the type column, the author could write “FR0” or “FR1” to set the value.
As an aside, the slope feature is a game changer and a real differentiator for your app. It helps to address the shortcomings of erg and resistance modes, especially for short intervals.
I don’t use Zwift so I am not totally sure, but it looks like there is also a “flag” on a ZWO file: show_avg=“1” where if this is set, the average power will be shown on a Zwift ride. Might be something else to look into along with the flatroad modifier
Oh I see, yes that would be a simple change. We might be able to get that soon 
Interesting. Let’s see if people request it.
