The whole running thing is starting to look a bit fuzzy, to me.. lot of factors that don't sdd up.
She is 50, she is expected at a girls brunch, she is a woman who takes time and trouble over her appearance, she would come home and shower and dress appropriately for this brunch. It was, as her friend said, important, for some reason.
She is 50 and not long recovered , so to speak , from Covid over Xmas, it is summer, 25 C is up there with weather to be concerned about if running, yet she takes no water. She doesn't look like a woman who takes unexpected risks, Taking water would be habitual.
No one has seen her running out on that track. This is a town that runs, like an Antipodean Eugene. Hard to believe she was the only one , the only one out that morning. People drive up from Melbourne, to 'run in the forest'... nuts', I know, but they do.
No one's camera has picked her up. This is the age of camera. On phones, on CCTV, on dashcam , on your watch, ....there are valuable properties around there, with valuable cattle, sheep, possibly, llama's, etc all filmed all the time.
