A double run is where a bus service turns around at a point mid-route and runs back the way it just came for some distance. There are numerous examples of these in the UK but which one would qualify as being the longest?
Qualifying distance must include both the outward and back stretches of any double run section (which would be both the same length), as well as any one-way loop which acts as the u-turn manoeuvre.
