I just like to make a suggestion to add the option to show the avarage pace on a interval while running it. Just like you can see on laps.
I believe the issue may be that for many people the intervals are going to be too short to allow them to compute a meaningful average pace.
This feature already exists in the LAP mode, so I use manual laps instead of intervals. If TomTom has so much trouble implementing average interval pace, then i say - bye bye TomTom. The other companies show that they can do it
