This race winds runners through Kennywood on a one-of-a-kind 5K, with an afternoon of friendly competition riding coasters to follow. A portion of proceeds from Kenny’s Koaster Race will go to the Cancer Caring Center, a Pittsburgh nonprofit dedicated to helping people diagnosed with cancer, their families and friends, cope with the emotional impact of cancer. Registration begins at 7 a.m., with the race starting at 8:30 a.m. See the website for more details.
