Course, timing and logistics

Timing uses electronic tags - wrist-worn HuTags or an electronic wristband - which record lap start and finish times via the event timing system. Runners must check out with the timing partner at race finish to finalise lap counts. Basecamp location 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 kit. Tentsmuir uses a pay barrier for parking with a day charge of £4.
