Trust 10K Run is a free 10K trail run held at Polesden Lacey near Dorking. The circular route explores the Polesden Lacey Estate and Ranmore Common, following woodland paths, estate tracks and countryside trails through the Surrey Hills.
Hosted by the National Trust on the fourth Sunday of each month, the run is open to all abilities and follows a permanent waymarked route. There are no marshals on the course, making it an informal event that encourages runners to enjoy the estate at their own pace.
The route combines varied terrain with sweeping views across the surrounding countryside, offering an enjoyable trail run in one of Surrey's best known National Trust estates. It is a popular choice for runners looking to explore scenic off road trails in a relaxed and welcoming setting.
