Good position of the map could be also left or right upper corner of the screen. In this way you avoid to visually cover the terrain details (stones, etc). If possible to have in the corner drop down box to use it only when you want to show a comparison of terrain with map animation/map image. To show map/terrain detail-control feature or mistakes which everybody could see/hear in the video; maybe also image of route choice on the whole leg. At crucial legs also image how much time runner lost/win on the leg.

In my opinion is no need to show image of the runner every time when he/she say something. Sometimes could be good to use just sound; audio/map audio/video. I prefer too see image of the runner full screen at the start/finish. I think that combination of three images: video/map animation/runner image gives a viewer too much information on one screen. I think that two of them in combination with audio are enough.

Video/editing is very time consumed so it is good to define which concepts are good to use it to tell the story. My favorite could be: Runner image - video/map - Audio/route choice on the leg or up to three route choices with marked mistake on the leg/full screen (not more that 3x times) - then showing only audio/terrain explanation with possible drop down box where you give viewer a close look where and how mistake was happened (image or map animation). Where runners ran without a mistake it is probably enough to show only terrain image or terrain/map animation in the corner like you did it. Sound good if you will be able to use correctly oriented map.

Runners usually speak about their mistake on the leg or how accurate they ran and I think that for post race video is appropriate use of runner’s audio/map or runner’s audio/video very important. It will be good to see which combination of different concepts really work together and how much time is good to use each one on the timeline.
