Runners take on 'Britain's Most Beautiful' marathon
Hundreds of runners will tackle the scenic and challenging Kielder Marathon in Northumberland today. The two day sporting event got underway on Saturday with a 10km race and 'run-bike-run' relay.
The marathon course which encircles the shoreline of Kielder Water is expected to attract thousands of runners and spectators. The mostly off-road route follows a circuit around Northern Europe's largest man-made lake.
