Introducing our newest event, The Iron Keep – 5 Hour Siege Run.

Set in and around a medieval village, this unique multi-lap endurance race challenges runners to complete as many laps of a 5km course, within five hours. Starting in full daylight and finishing after dark, the event evolves as the hours pass — with the village coming alive under torchlight, traditional music echoing through the square, and spectators lining the course for every lap.

​

Whether you race solo or as part of a pair or quad, The Iron Keep is as much about strategy and atmosphere as it is endurance. With a central village hub, team camps, a tavern-style aid station, and fancy dress strongly encouraged, this is not just a race you run — it’s an experience you become part of. From first lap to final bell, The Iron Keep delivers a truly unforgettable day-to-night challenge.
