I plan to add a "target workout" feature in the future which allows you to compare your pace with that of a previous workout, in the same way as the current "target pace" feature works against a configurable average pace. So you would have metrics for how far ahead or begin you are, and also a yellow icon on the map showing the position of the runner in the target workout.Yes, that is bad.
Was playing with the idea to feed this cool feature with preplanned race files just like Garmin PacePro does. But this seems impossible now.
I plan to allow for this when improving the route navigation, but may not include it in the first version with those improvements.
