The Lullingstone 10k start location (what3words ///famous.rocks.school) is on the left hand side of the main meadow at Lullingstone Country Park. The route takes you west, straight up the left hand side of the meadow into the woods. The course continues through the Lullingstone golf course, looping out towards Lullingstone Castle and then back to the main meadow ready for lap 2.
It's an undulating course with some spectacular views across the Darenth Valley.
