FIT fund-raisers will be able to pound the paths through a secret estate at an annual event.
Few get to see behind the walls of the private Lambton Estate, the ancestral home of the Earls of Durham, near Bournmoor.
But each year it opens its gates to allow runners to race through its picturesque grounds.
This year The Foundation of Light, the official charity of SAFC, will host its Lambton 10k run and 3k fun run on Sunday, June 29.
The 10k run, which attracts about 700 entrants, is designed for competitive and non-competitive runners, while the 3k, which sees about 300 people take part, offers fun for families and children.
Participants will run past the historic buildings, which have been used for the setting of BBC drama The Paradise.
Jemma Garrett, events coordinator at the foundation, said: “The Lambton 10k and 3k event is one of the most unique on the running calendar and certainly offers one of the best backdrops.
“Every year competitive runners and fun runners from across the North East line up to take part and we’re hoping for a record turnout in 2014.”
Entries are open for the runs, sponsored by Cestria Community Housing, with a fee of £12 per person for the 10k and from £6 per person for the 3K.
Proceeds will fund sport and education-based programmes, which benefit 42,000-plus youngsters and families across the North East every year.
