The timing system uses HuTags on velcro wrist straps that register each lap with the timing monitor. Runners must not cover the tag and must check out with the timing team at race finish to finalise lap counts. A finisher prize is available for collection at the event basecamp gazebo. Basecamp is marked on the event GPX map and includes two 6 x 3 meter gazebos for kit storage; the organiser does not accept liability for lost items. Spectators are welcome at basecamp. Parking at Tentsmuir uses a pay barrier and costs £4 for the day.
