A brisk walk criss-crossing the picturesque Darent Valley. The lunch stop will be at around 9 miles' distance at Lullingstone Country Park where there are toilets and a cafe. A total ascent of over 750 metres made up by some individually steep climbs - also aiming for an average pace of around 3.3 mph if conditions are dry, so a good level of fitness is required.
Please bring a packed lunch. Pub at the end of the walk.
OPTIONAL DROP OUT POINTS: for those wanting the challenge of a fast walk with some steep climbs, but not sure whether to commit to the full distance, the walk passes Eynsford Station (6 miles distance) and Shoreham Station (14 miles distance).
