Interesting. Having watched all of the videos that Asher has available (https://goo.gl/photos/oK8L339ndAqJFZiPA), none seem to match the one Rob posted on his Facebook page (https://www.facebook.com/marathonmanuk/videos/1026629384087986/). Notice the pink car is clearly visible from a distance in Rob's video. Not that it makes any difference, but did they actually obtain the video?
My impression was they contacted the owner for the footage. Check the comments on his strava run through Emporia.
Yes, they contacted the owner, and obtained a copy from him.
