BBC News, North East and Cumbria<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n The search for a missing woman has entered its fourth day, police have said.<\/p>\n Jenny Hall, 23, was last seen leaving her home at Barracks Farm, Tow Law, County Durham, on Tuesday just after 15:00 GMT. Her red Ford Focus was found parked on the B6278 between Eggleston and Stanhope on Wednesday.<\/p>\n Ms Hall, a keen long-distance runner, is described as 6ft (1.8m) tall with very long dark hair and was last seen wearing a blue hoodie with a John Deere logo and dark jogging bottoms.<\/p>\n Durham Police said it would be working in Hamsterley Forest, where Ms Hall was known to run, and the surrounding areas.<\/p>\n<\/div>\n Hamsterley Forest was created by Forestry England in the 1920s. <\/p>\n Sections are used for lumber production, but the area is also popular with walkers and cyclists.<\/p>\n Spanning 4,942 acres (2,000ha), it is the largest woodland in County Durham and is located about 16 miles (26km) from the town Ms Hall is from. <\/p>\n It attracts about 200,000 visitors a year, according to Forestry England.<\/p>\n Ch Insp Haythornthwaite said he wanted to thank those who had contacted them with information so far.<\/p>\n “We really do appreciate your help and support,” he said. <\/p>\n He said the force was aware that families would be walking around the forest recreationally today and asked them to give space to officers conducting the search. <\/p>\n “Try not to disrupt the search area,” he said. <\/p>\n<\/div>\n Alongside the police, Teesdale and Weardale Search and Mountain Rescue Team (TWSMRT) said its teams had so far searched over 60 miles (96.5km) of paths and tracks in Hamsterley Forest.<\/p>\n “The biggest challenge is the area size itself and the terrain,” said volunteer Peter Bell. “The terrain is muddy and boggy.”<\/p>\n A spokesperson for TWSMRT previously thanked the public for offers of help, but individuals were advised not to try and assist as it could “hamper the systematic search”.<\/p>\n<\/div>\n Motorbike officers, specialised sniffer dogs and air support drones have also been involved in the search so far. <\/p>\n Durham Police is urging anyone with any information to ring 999.<\/p>\n<\/div>\n <\/div>\n![\"Family](\"https:\/\/ichef.bbci.co.uk\/news\/480\/cpsprodpb\/221a\/live\/060ef2a0-f044-11ef-afe3-3909ee34e697.jpg.webp\")
