1, Pacers should be marked on the small map by a coloured dot to show where they are within the pack.
2. Average speed needs to be selectable to show on the UI screen somewhere.
3. Percentage of Max HR as an average and currently, needs to be available on the main screen as some coaches want you to work to that level even when just riding with a pacer or in a race.
4. Some more interesting landscapes that are winding paths within trees or through woods would be good.

Hope that makes sense,
