The Iron Keep 5 Hour Siege Run is an endurance trail running event in Central Scotland near Denny, featuring a multi lap course set around woodland and parkland terrain. Runners complete as many laps as possible within a five hour time limit, with the route looping through a themed event village and surrounding trails. 

The course combines forest paths, open park sections and firm off road trails, creating a consistent loop that changes atmosphere from daylight into evening. The setting is designed around a medieval inspired village environment, with runners passing through a central hub on each lap. 

This Central Scotland endurance race is aimed at runners looking for a timed ultra style challenge rather than a fixed distance event, offering strategy, pacing and repeated trail laps in a unique themed running environment.
