Running represents a way to stay healthy, active and sane as a mother, Roe said. It also helped her lose 100 pounds, a quest she started in 2007.
"When I first decided to run it was kind of like a dare to myself," she told Daily Voice. "It was so absurd. I might as well have told people I was going to the moon."
She started at 250 pounds but progressed as she ran more. Roe, 43, ran several 5Ks and half-marathons, but Sunday's New York City race is her dream event.
Roe lives with her husband, Martin, and 8-year-old son, Benjamin.
When she hits the course, Roe will join the Jersey Women Strong team. The group will run together, and it helps make an individual sport more exciting, she said.
She met several other women like herself along her way who made drastic body changes. Their stories, along with her own, inspired her to make a documentary about it, titled "From Fat to Finish Line."
"You learn so much about yourself when you're a runner," Roe said. "You start to realize you can accomplish things you never thought possible."
