On Sunday morning, Samantha Murphy laced up her shoes and headed out for a run.
Murphy, a 51-year-old mother-of-three, left about 7am on February 4 for Woowookarung Regional Park near her home in Ballarat East, an area she ran in almost daily.
But this time, she never returned.
Police said the 51-year-old's disappearance is out of character, with the search for her now extending into its second week. She was last seen wearing black half-length leggings, a maroon or brown singlet and an Apple Watch.
Police are asking residents in the area to review their CCTV footage from between 7:00am and 11:00am on February 4 for sightings.
Search 'scaled back' after a week of no leads.
Six days after Murphy's disappearance, police scaled back the search for her but said the investigation continued.
"The investigative stage of the investigation continues and as any new information comes to hand identifying areas of interest, the search will be scaled up.
"Police continue to be in regular contact with Samantha's family regarding the developments of the search and the status of the investigation."
Volunteers have continued to search through the local area.
Victoria Police's Missing Persons Squad, which took over the search on Friday, renewed calls for any footage taken in the area around the time of Murphy's disappearance, including from home CCTV and dash cams.
