Finish time predictor in races

Cycle down to "Training Status" widget, click the start button. Cycle down to "Race Predictor".

That's the one that shows you what you can expect to achieve for the main distances, but the one I'm meaning is whilst you are running and it intuitively knows what your finish time is going to be?  Thanks

I saw this answered in another post.  It is under activity options "Set a Target".

In the documentation you have the "Setting a Training Target" bullet where you can see how to do that:

I believe you can use the Virtual partner as well to get a same/similar feedback.
