Grafham Water running loop

Embark on the Grafham Water running loop, a moderate 8.8-mile (14.1 km) journey around England's third-largest reservoir, offering a rewarding experience for joggers. You will gain about 238 feet (73 metres) in elevation over approximately 1 hour and 34 minutes, traversing well-maintained paths that vary from paved sections to gravel and natural earth. The trail provides consistent, expansive views of the water, especially from the impressive Grafham Dam at the start, and winds through peaceful woodlands, open parkland, and grassy banks, with notable features like the iconic Valve Tower and Sanctuary Bay along the way.

This multi-use path is popular with cyclists and walkers, making it a lively spot. You will find convenient facilities such as a visitor center, cafes, and picnic areas, perfect for a post-run refuel or a family outing. While most of the loop is off-road, be aware that about 1.5 miles at the southern end runs on a road. The varied surfaces and generally flat terrain make it accessible for different fitness levels, though the full distance requires good endurance.

Grafham Water is a designated Site of Special Scientific Interest, boasting a rich natural environment with diverse wildlife. As you jog, you might spot various birds from strategically placed hides in the reed beds and wetlands. Created in the 1960s as a reservoir, the area now hosts organized running events, including 10K and Half Marathon trail races, adding to its appeal as a premier destination for outdoor activity in Cambridgeshire.
