The Polesden Lacey Trust 10K is a free monthly trail run organised by the National Trust near Dorking in Surrey. Held on the fourth Sunday of each month, it welcomes runners of all abilities to explore the estate and surrounding countryside at their own pace.
The circular 10K route passes through the historic parkland of Polesden Lacey and the woodland of Ranmore Common. Runners follow a permanently waymarked trail featuring long climbs and descents, with some steep sections and a mixture of muddy, gravel and uneven paths. The course is self guided, with no marshals stationed along the route.
Starting from the main visitor car park, the run requires no advance booking. Dogs on leads are welcome, and toilets are available near the coffee shop. The informal format makes it a relaxed way to experience the Surrey Hills without the pressure of a competitive race.
