Chip timing is being used and teams must register at the recording boxes, sited at each checkpoint. Runners must wear their race number on their chest and show the number to marshals when asked. This enables runners to be monitored and safety maintained.
The event is a senior competition for athletes aged 18 and over, but suitably experienced juniors aged 16-17 may run leg 4.
Parts of the course are over technically challenging ground and all competitors take part at their own risk. It is the duty of all competitors to help any runners who is in need of assistance.
