Race The Tube - High Speed 1 vs The Underground

I caught up with Andy from 'Calling All Stations' again, as we wanted to test out another fastest way between two points in London.
As SouthEasterns High Speed 1 line doesn't appear on the Tube Map (because it's not a TfL service) you might overlook it as a way of getting to Stratford from King's Cross St. Pancras. But how long does it take anyway?
Andy brought along two of his friends - Victoria and David, and we all went different ways to see which was the fastest!
