On Saturday the second Northern Ireland Cannonball Run is taking place from the Shaw's Bridge Sports Ground in Belfast. They're raising money for the Northern Ireland Leukaemia Research Fund.
You may have noticed in the quote
The concept of the Cannonball Run is as follows: Teams of three people will be deposited at a mystery location (in any of the nine counties of Ulster), and be required to make their way back to Shaw's Bridge without any money or assistance (no mobiles or GPS!). Various tasks will need to be completed along the way, and teams will need to follow a designated route.
and teams will need to follow a designated route.The word used, describing the route they take, is designated.The word is not, traditional. So they shouldn't encounter any counter demonstrations.
