The Charborough Estate

The perfect race for a personal worst time.

The route cuts through roughly 600 acres of dense, thick woodland. Coarse underfoot — roots, ruts, mud, low light and that quiet, oppressive woodland atmosphere where time feels slightly warped.

A great place to set a personal worst and wear it with pride.

Domesday Book

Deep inside the woodland of Charborough Estate, there is a tree.

Not signposted. Not celebrated. Just there. It stood when England was counted and measured in the Domesday Book. If trees kept receipts, this one would have seen some things.

Arrive. Gather yourself. Question your decisions.

A covered base to settle in before heading into the forest. Space to stand around, talk, eat and drink. Once you've made it back out — a place to sit, recover, and compare stories from the trees.
