The trail goes through the grounds of the 2,000 acre Holdenby Estate and on surrounding farmland with fantastic views of the country house, finishing through the iconic arches that adorn the grounds.
The route takes in this wonderful area, and is varied in terms of terrain and challenging as a result. There are no time limits and runners of all abilities are welcome to come and take part.
A great chance to stretch your legs with this Halloween with the Piece of String - at night!
