Entry includes a detailed route description, refreshments at checkpoints and the finish, and a certificate. There is a cut-off time at Checkpoint 3 for the 32 mile route; participants arriving after that time will be required to follow an alternative route. Dogs are allowed but must be kept on a lead; dogs are not permitted inside Cilcain Village Hall. Under 18s must be accompanied by an adult.
