As you can see in the depicted screenshots, the quality is phenomenal.
The Map data goes from a National Map scale down to a very detailed map with properties, buildings and roads.
To view the map data, switch to the openStreetMap source and then zoom in somewhere in Norway, TrailRunner will automatically select the new source and display the background map.

Vidar pointed me to this beautiful map source that — unfortuanetly — is limited to Massachusetts, USA. The map is an interesting montage of several layers and data sources Lars Ahlzen has accomplished.
If you choose the openStreetMap as your background map in TrailRunner and view the area covered by this map server, TrailRunner now uses this source.

If you didn’t know yet, the cycle map is based on the very same data as the OpenStreetMap project but uses a specialized map renderer for outdoor activities. At low zoom levels it is intended for overviews of the National Cycle Network; at higher zoom levels it should help with planning which streets to cycle on.
The new maps now display a elevation contours and hill coloring and have cycle lanes marked on streets within cities.
You might want to reload your maps if you want TrailRunner not to display the old cached imagery. You can either use File > Consolidate > Reload Background Maps or remove the whole cache directory from your home directory under yourHome/Library/Application Support/TrailRunner/GeoTiles/openstreetmap.org
