The Active Northumberland Kielder Run Bike Run follows an almost entirely off-road course around northern Europe’s largest man-made lake, Kielder Water, in Northumberland.
Britain's 'most beautiful' marathon is back! The course which encircles the shore line of Kielder Water will attract thousands of runners and spectators.
While the adults are out tackling Britain’s Most Beautiful Marathon back at Leaplish Waterside Park our next generation of runners show us what they’re made of!
