Agreed, I am also an experienced runner and this would be wonderful. Assuming it can get GPS and map trails, trail running would be vastly improved by this. Right now people have to paint trees every 20 feet or so to mark the trail, but if you have a live HUD it can tell you if you're on or off course fairly quickly.
Trouble is GPS isn't always reliable in heavily wooded areas, so there might need to be improvements in GPS before that is really viable.
