Runners can have their own Support Team/Crew to Support their Race.
At Village Hall locations, no more than two Support Crew members supporting an individual runner are permitted in a Village Hall at any one time. These must not impede the Event team nor other runners. Some of the Village Halls are medium sized Halls so to have 3 or 4 crew members for one runner limits the space.
Support crews must not take the food nor drink from the Village Hall except for their runner unless given permission to do so.
Support Crews must 'respect' Event Staff and are not permitted into the kitchen area unless given permission to do so by the Checkpoint Manager.
Failure to do so will result in the Support crew being asked to leave the Venue and possible time implications or disqualification of the runner.
Further access points due to be released...
