About The Iron Keep 5 Hour Siege Run
Taking place on 5 September 2026, the Iron Keep 5 Hour Siege Run sees runners tackle a trail-based multi-lap challenge set within and around a medieval-style village in Denny, Falkirk. Participants have five hours to complete as many full laps as possible, racing individually or as part of a team. The course loops through the village heart, passing spectators and team camps with each circuit.
The event begins in daylight and transitions into evening as torches light the course and traditional music fills the square. This transformation creates a distinct atmosphere across the race duration, with the setting evolving from a bustling race hub into a dramatic night-time fortress as darkness falls.
