@bobblebardsley The loops are done clockwise, then clockwise until loop 5, when the first runner gets a choice of direction and then any others run in alternate directions. Counter clockwise is apparently slightly quicker but clockwise is considered easier to follow (although it's all relative!)
@BarclaysUKHelp after spending 2 hours on hold to you over the weekend with no one picking up, I decided to try again today. One call was cut off after 15 mins on hold, and my second was disconnected after 46 minutes. Please tell me how I can speak to a human!
Everyone needs to watch Murder In The Car Park on C4. I've followed the story ever since seeing @AlastairMorgan at Hay. His book Untold goes into far more detail but it is criminal that so few people know Daniel's story.
