KINGSPORT — The Ballad Health and Niswonger Children’s Hospital Crazy 8s 8K road race, set for the night of Saturday, July 14, is back for its 28th year — but the last on its current course. Race co-director Hank Brown announced Wednesday that the figure-8 course will be different starting in 2019. “We’re going to try to make it flatter and we’re going to cut out the hill,” Brown said during a news conference at Food City on Eastman Road.
