Hundred Hills South Section

Route Overview & Local Insights

Experience the rugged beauty of The Chilterns on this challenging 26.5km loop, which mirrors the southern section of the famed Hundred Hills course. Starting from the picturesque village of Hambleden, runners will tackle 509m of vertical gain across a mix of rolling chalk downs and ancient woodland trails. While the route features significant paved sections, the "Hilly" rating of 3 tells the real story—expect technical climbs and sweeping descents that will test your endurance. The terrain is quintessential English countryside, shifting from firm trackways to undulating ridge paths that offer expansive views of the valley below.

Hambleden and the surrounding Chiltern Hills Area of Outstanding Natural Beauty (AONB) are steeped in history, frequently serving as the backdrop for classic British films and period dramas. As you run through this landscape, you are traversing land that has remained largely unchanged for centuries, characterized by its distinctive flint-and-brick architecture and historic bridleways. Local runners know that the valley floor can hold moisture, but the higher ridges provide some of the best high-mileage training ground in Southern England. This route offers a true taste of the challenging topography that makes the Buckinghamshire countryside a premier destination for trail and ultra-runners alike.
