14k Run Huntingdonshire: Scenic Loop Around Grafham Water

Route Overview & Local Insights

Experience one of Cambridgeshire’s finest endurance loops with this 14.3km anticlockwise perimeter run around Grafham Water. Despite the significant distance, the route is remarkably accessible for runners looking to build mileage, offering a predominantly flat profile with a mere 32m of total ascent. You will navigate a well-maintained mix of paved sections and hard-packed gravel paths that hold up excellently in all weather conditions. Expect sweeping reservoir views, refreshing lakeside breezes, and a sense of "getting away from it all" as the trail winds through woodland clusters and open shoreline, making it an ideal choice for steady-state long runs or marathon base training.

Steeped in local history, Grafham Water was created in the 1960s to meet the growing water demands of Milton Keynes and the surrounding Bedfordshire area. Today, it stands as England's third-largest reservoir and serves as a vital Site of Special Scientific Interest (SSSI). As you round the western edge, keep an eye out for the ancient woodlands and the diverse birdlife—including the famous ospreys that frequent the area. Starting and finishing near the Marlow or Mander Car Parks provides easy access to post-run refreshments, offering a classic "Saturday morning" ritual for the local Huntingdonshire running community.
