Kielder Marathon

The Kielder Marathon, known as "Britain's Most Beautiful Marathon," takes place around Kielder Water, England's largest man-made lake. Set in the stunning Kielder Water & Forest Park in Northumberland, this race offers a unique blend of natural beauty and athletic challenge. Runners follow a largely off-road course that hugs the shoreline, winding through forests and over rolling hills. The marathon's breathtaking scenery, including views of the lake and surrounding landscapes, provides a memorable backdrop for this test of endurance. With its mix of terrain and elevation changes, Kielder Marathon offers a rewarding experience for both seasoned marathoners and first-timers alike.
