There is a care post at every five kilometers of the course. The runners are provided with drinks here. You help set up the post and hand out drinks to the runners.
We need people who will help the runners with entry to the various starting pens, hand out medals and give out drinks to runners who have completed the race. As a start/finish colleague you fulfill one of these tasks.
To guarantee the safety of the runners, the course must be kept free of traffic. Traffic controllers do this; among other things, they prevent vehicles entering streets that come out on to the course. Minimum age for this role is 18.
