KINGSPORT — Janice Irvin marked the year she turned 26 by running the 26 miles of the Flying Pig Marathon in her hometown of Cincinnati. This year, on May 5, she ran half that marathon and raised almost $30,000 to help replace the playground at Kennedy Elementary, where she is principal and the school’s mascot is Coyotes. Kennedy, along with Johnson Elementary School across town, is raising money for a playground replacement. “I said I was never going to run it again,” Irvin said.
