The trial for her accused killer, Michael Ledford, began earlier this month. Last week's testimony, often brutally graphic, brought back concerns about safety.
Many cyclists worry that the path has long stretches of secluded segments, especially the farther one gets from the trailhead on Mavell Road, near Nickajack Elementary School in Cobb County. There have been several incidents since Ewing's death, including robberies of cyclists.
Suva Shrestha, who owns a gas station in Powder Springs, had a scary experience on the trail five months ago. He said a strange man who walked with an exaggerated limp approached him and his 21-year-old daughter when they stopped to pick wild grapes. The man grabbed his daughter from behind and kissed her, Shrestha said.
"She was very scared; she was trembling," Shrestha said.
Police arrested the man when he showed up on the trail the next day, and he was subsequently convicted of simple battery, Shrestha said. Despite the unsettling encounter, Shrestha said he still takes daily walks on the trail. He makes a point of telling women who are unaccompanied to be careful.
"I tell them, don't walk alone," Shrestha said.
Page Smith, 61, of Smyrna, was bicycling with two friends along a 12 1/2-mile segment of the trial on Friday. Asked about the issue of safety on the path, Smith chuckled, "I see cops occasionally, but not very often.
"It's kind of ride at your own risk," Smith said.
She said she is closely following news of Ledford's trial. Some of the recent testimony rattled her, but Smith said she hasn't let it stop her from taking a solitary spin on her bicycle. For many, the lushly forested trail continues to be a welcome respite from sprawling suburbia and the bustling city nearby.
"[Ewing's murder] gives me pause, but you can't live your life afraid of everything," Smith said.
