About Kielder Marathon
The Kielder Marathon takes runners on a 26.2-mile route around Kielder Water in Northumberland, threading through forest tracks, lakeside paths and across undulating terrain in England's largest woodland. The course combines varied trail surfaces with panoramic views across the region's distinctive landscape, offering a scenic challenge through one of the UK's most recognised marathon settings.
Taking place on 4 October 2026, the marathon forms part of a wider Kielder Marathon Weekend that also features a half marathon, 10K, junior races and a gravel duathlon. The event is organised by Events of the North and includes finisher medals and goody bags, alongside practical support including secure baggage facilities and a park and ride system.
