Kielder Marathon Weekend

Altra Kielder Marathon Weekend takes place at Kielder Forest, Northumberland, around Northern Europe’s largest man-made lake, Kielder Water. The event offers Marathon, Half Marathon, 10K, Gravel Duathlon, and Junior races, with the Marathon and Half finishing the weekend alongside the other events. The almost entirely off-road course loops around the lake, described as Britain’s Most Beautiful Marathon, delivering a remote, scenic atmosphere.

Finisher perks include a medal and goody bag for all, a FREE Park & Ride system, spectator passes with shuttle buses, secure baggage drop, local produce, and prizes for the top finishers and age-group winners. It’s a family- and spectator-friendly weekend. Visit the organization's website for the most recent information.
