Emma Langworthy has been found alive after a day of intensive searching in One Tree Hill.
Ms Langworthy*was found just as searchers were about to call off the search for the night.
Ms Langworthy, 18,*contacted a friend before she*went*jogging*in the One Tree Hill area about 3pm*on Wednesday.
She had*not been seen since.
After searching for her all day, police had planned to call off the effort at 6.30pm on Thursday and continue again at first light Friday.
"The longer it goes with these conditions - cold, wet, windy - the less her health will stand up to it," search leader*Inspector Michael Talbot said.

"We hope she will be safe and well when, and if,*she is found.
In a statement on Thursday afternoon,*Ms*Langworthy's*brother*James said his sister had epilepsy and there had been increasing fears for her safety.
"Emma suffers from epileptic seizures and needs medication. The seizures can lead to*moments of disorientation and extreme fatigue. She has now been missing for close to 24 hours and we are obviously concerned for her wellbeing."

"She sent a photo to her friends indicating that she was here.

"It's believed she ran further into the hill and down the other side, where she sent some text messages to friends. But since then there's been no communication from her."
Ms*Langworthy*hails from Canberra, where she attended Radford College,*and moved to Victoria to study at La Trobe University's Bendigo campus.
Police mounted a large-scale search, involving the Air Wing, the dog squad and the State Emergency Service,*for the teenager on Wednesday night.*The search resumed*on Thursday morning.
Police had been focussing their efforts on several hectares*of bushland east and west of the One Tree Hill Lookout,*about 7 kilometres*south-east of Bendigo.
Earlier, Senior Sergeant John Dalton told media that*Ms*Langworthy's*mobile phone was*off.
"We want to be able to discount the fact that she might be sitting at a friend's place with her phone off," he said.
Ms*Langworthy's friends and family are*also*helping*in the search and are handing out flyers with her photo around town, the Bendigo Advertiser has reported. A group of more than 15 students and staff from the nearby La Trobe University campus, many of whom know Ms Langworthy,*are also*assisting with the search.
It is understood*her parents are overseas, but "waiting by the phone".*
The temperature dropped to minus*1*degree in Bendigo overnight, according to the Bureau of Meteorology.
The One Tree Hill area,*is popular among*joggers and cyclists.*But police were worried Ms*Langworthy*may have left the track.
Bendigo Oral Health and Dentistry Society offered support to Ms Langworthy's*peers, as the search continued.
"We will be posting hourly updates as we receive them informing dentistry students of the current progress," the society said in a statement on its Facebook page.
"There is a sweep occurring on the university campus this morning, as well as professionals searching One Tree Hill."
Radford College principal Fiona Godfrey said the school offered support and pastoral care to students who know*Ms*Langworthy, as well as staff who teach*her.
"The thoughts, hopes and prayers of the entire Radford College community are with Emma Langworthy and her family at this time," Ms Godfrey said.
Ms Langworthy and her family hail from*Gundaroo, which is a village about 30 minutes*drive from Canberra.
Cork Street Cafe owner Bridget Hinves said Ms Langworthy had worked at the Gundaroo eatery throughout high school.
"She's the most enthusiastic, fun-loving, sporty, wonderful young woman; she has such a vibrant personality."
