After climbing all the way to the top of the hill and following the North Downs Way for about an hour, the route dropped back downhill into the village of Otford which I have mentioned before in My Darent Valley Walk Part 2.
The route passed close by the remains of Otford Palace originally built for the Archbishops of Canterbury but later seized by King Henry VIII.
Twitton can't even be classed as a village as it consists of only a handful of ancient farms including Filston which served as check point 1. Distance covered 4.7 miles (7.62 km).
At each check point the organisers had laid on complimentary refreshments which were very welcome as it was a hot day. After leaving Filston Farm there was another steep climb to the top of the valley.
A field full of daisies. As I crossed a stile at this point I spotted a lizard but unfortunately he shot off like a rocket before I could get a picture. Somehow I don't think I'll end up being a wildlife photographer....
The poppies are amazing this year and can be seen for miles. Shortly after passing the field full of poppies, Lullingstone Castle came into view.
I dropped down to the foot of the hill and followed my old friend the Darent Valley Path to check point two at the Lullingstone Visitor Centre.
Check point two - distance covered 9.8 miles (15.2 km). A quick sandwich and a drink before pressing on along the Darent Valley Path through Shoreham village then back up the other side of the valley to the little hamlet of Romney Street.
Romney Street consists of a handful of houses and The Fox and Hounds pub which also doubled up as Check Point three. The pub features in many books about walking in Kent and was a welcome oasis after a long uphill slog.
Check point three. Distance covered 15 miles (24.19 km). My knees beginning to ache a bit at this point but I couldn't give up.
The Battle of Britain Memorial Flight Lancaster flew over low and slow heading towards London.
The church is located in the amusingly named Tinker Pot Lane. Next door to the church is a hall which was the location for the final Check Point.
Check Point four. Distance covered 17.71 miles (28.5 km).
A welcome sight as by now my knees were very sore!
The weather stayed kind and the views from the top of the Downs were stunning.
I came across this friendly cow munching on the grass minding her own business. One of her bovine friends on the other hand decided to go on a mini adventure....
