Grim's Ditch

Highlight • Forest

There are many prehistoric bank and ditch earthworks in the Chiltern's region, and many share the name Grim's Ditch or Grim's Dyke. This one is thought to have been a border between Iron Age kingdoms and runs for 5 straight miles (8 km) from Mongewell on the River Thames to Nuffield on the Chiltern escarpment. Today, the Ridgeway National Trail makes good use of it.

King William IV Pub

Highlight • Viewpoint

The pub is a great place to stop for food and drink on your run. What makes this one particularly special, aside from the good food, is the view that you get from the outside here of the beautiful Chiltern hills in the area. They've placed some benches on the opposite side of the road: just sit down and enjoy!
